See Figure 3-1 and Table 3-1. ------------------------------------------------------------ WARNING ------------------------------------------------------------ Failure to adhere to the disk or tape drive add-on order sequence can cause cabinet instability, resulting in damage to equipment and/or personnel. ------------------------------------------------------------ The procedures for installing an add-on disk or tape drive depend on the disk drive position and cabinet level in which the storage element is being installed. In all cases, the disk or tape drive installation procedures describe installation from the front of the cabinet. Preparation and Installation 3-1 3.1 Add-On Disk or Tape Drive Order Sequence General rules: 1. DSSI has first priority. That means, you mount DSSI in accordance with the storage array cabling diagrams (see Appendix A). Mount additional SDI storage elements in the free slots remaining. · Start mounting tape elements top right position. · Continue to mount tape storage elements from top to bottom. · Start mounting disk storage elements in the right bottom position. · Continue mounting disk storage elements from bottom to top. 2. Second priority, if there are no DSSI storage elements: · Start mounting RA9x disk drive in positions 1-2 and 5-6 first. For this position, use the chassis stabilizer brackets. · Mount SA7x storage elements in the remaining slots. 3-2 Preparation and Installation 3.1 Add-On Disk or Tape Drive Order Sequence Figure 3-1 DECArray300 Cabinet System Preparation and Installation 3-3 3.2 Add-On Disk or Tape Drive Positions 3.2 Add-On Disk or Tape Drive Positions Table 3-1 Specific Sequence Position of the Storage Elements ------------------------------------------------------------ Storage Element Sequence Position ------------------------------------------------------------ Disk elements first add-on in pos. 1-2; second add-on in pos. 4-3; last add-on in pos. 6-5 Tape magazine elements first add-on in pos. 5-6; second add-on in pos. 3-4 ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ Although it is possible to install the TF857 in position 1-2-, this is not recommended becuase the tape loader contains mechanical devices, which might be sensitive to dust and high particle concentration. See Table 3-1. ------------------------------------------------------------ Table 3-2 Specific Sequence Position of the DSSI Disk Storage Elements ------------------------------------------------------------ Storage Element Position ------------------------------------------------------------ SF1-first SF storage element to install Position 1 SF2-second SF storage element to install Position 2 SF3-third SF storage element to install Position 4 SF4-fourth SF storage element to install Position 3 SF5-fifth SF storage element to install Position 6 SF6-sixth SF storage element to install Position 5 ------------------------------------------------------------ Table 3-3 Specific Sequence Position of the DSSI Tape Storage Elements ------------------------------------------------------------ Storage Element Position ------------------------------------------------------------ TF1-first tape loader storage element to install Position 6 TF2-second tape loader storage element to install Position 5 TF3-third tape loader storage element to install Position 3 TF4-fourth tape loader storage element to install Position 4 ------------------------------------------------------------ 3-4 Preparation and Installation 3.2 Add-On Disk or Tape Drive Positions Example 1: Two RA90, one SA72, and two SF72 should be mounted. · First priority is DSSI. Therefore, mount the two SF72 to positions 1 and 2. · Second priority is the RA90. Therefore, mount the RA90 to positions 5 and 6. Use the chassis stabilizer brackets. · Mount the SA72 to position 4. Example 2: Two SF72, one TF857, two RA92, and one SA70 should be mounted in the cabinet. · First priority is DSSI. Therefore, mount the SF72 to positions 1 and 2. Mount the TF857 tape loader magazine to position 6. · Second priority is to mount the RA9x to the top or bottom slots. Therefore, mount the first RA92 to position 5. Use the Stabilizer brackets. · Fill the rest of the open slots with the SDI storage elements. For example, you might mount the SA70 to position 4 and the second RA92 to position 3. Example 3: There are two SA72's mounted to the storage cabinet to positions 1 and 2. The customer would like to add one SF72 storage element. · First priority is DSSI. Therefore, the SF72 Storage Element should be mounted to position 1. Remount the SA72 from position 1 and mount the SF72 to position 1. Another possibility is to mount the first SF storage element in position 4. Nevertheless, cable the first DSSI storage element as SF1 and label it accordingly. · Mount the second SA72 to position 4 in case you mounted the first SF storage element into Position 1. 1. Upper level disk or tape drive installation When installing an add-on RA9x storage element to positions 6 or 5 of the cabinet, it is necessary to remove the cabinet top cover. The drive chassis stabilizer bracket cannot be removed from the frame and attached to the upper level disk drive without first removing the cabinet top cover. See Section 3.7. Each upper level disk or tape drive is supported by two chassis retainer brackets (top and bottom). Only for the RA90/RA92 you need one chassis stabilizer bracket, and two (top and bottom) rear lock-down brackets with one U-clip each. Detailed instructions for removing/installing this hardware are found in Section 3.12 and in Section 3.17. Preparation and Installation 3-5 3.2 Add-On Disk or Tape Drive Positions ------------------------------------------------------------ Note ------------------------------------------------------------ A DECArray300 cabinet system with only one Sx300 disk or tape drive in positions 1 or 5 will have a 25-pound stabilizer plate (weight) attached to the underneath of the upper cabinet H-stiffener. This is required to fulfill the requirement of stability in accordance to IEC 950. ------------------------------------------------------------ 2. Center level disk or tape drive installation When installing an add-on storage element, each storage element is supported by two chassis retainer brackets (top and bottom). 3. Lower level disk drive installation Before installing an add-on disk drive in the lower level of the cabinet (positions 1 or 2), it is recommended to remove the cabinet kick plate in Section 3.9. Each lower level disk drive is supported by two chassis retainer brackets (top and bottom). For mounting RA9x storage elements, you have to remove the cabinet kick plate and mount the cabinet stabilizer brackets. 4. No more than two storage elements Do not mount more than two SA70 storage elements per cabinet. You might violate the FCC or VDE 0878 requirements. 5. EMC finger strips Some of the SA7x storage elements might have EMC finger strips on top of the chassis. The EMC finger strips are not necessary for the Sx300 cabinet. For mounting top positions, remove the EMC finger strips prior to sliding the storage element into the cabinet.) 3.3 Electrostatic Discharge Electrostatic discharge (ESD) is caused by the build up and release of static electricity. An electrical charge from a person or object can damage hardware components and result in premature device or option failure. Use the following guidelines when handling static-sensitive components and modules: 1. Read all instructions and installation procedures including the static control materials and kits. 3-6 Preparation and Installation 3.3 Electrostatic Discharge 2. Wear a properly grounded ESD wrist strap when handling modules, components, or static sensitive devices: · Make sure the wrist strap fits snugly for proper conductivity. · Attach the alligator clip securely to a clean, unpainted, grounded, metal surface such as the drive or cabinet chassis. · Do not overextend the grounding cord. 3. Use static-protective containers to transfer modules and components (including bags and tote boxes). The ESD grounding strap for the DECArray300 cabinet system is attached to the rear bustle inside the rear panel of the cabinet. ------------------------------------------------------------ WARNING ------------------------------------------------------------ Do not attempt the following procedures unless you have taken proper precautions against ESD. Wear an ESD grounding strap with the clip end securely connected to a known grounding point while removing the storage element operator control panel (OCP) or other ESD-sensitive components. ------------------------------------------------------------ 3.4 Removing and Replacing the Cabinet Front Bezels Remove the cabinet front bezel as shown in Figure 3-2: 1.

The 110/120 Vac version of the cabinet are preconfigured with power cords for all six possible positions. 3.19 Applying Power This chapter describes the Sx300 storage element switches and power controller power connector configurations encountered when installing a disk or tape drive in an DECArray300 cabinet system. Brief descriptions of the power controller switches, the storage element voltage selector switch, and the circuit breaker are included. This chapter does not discuss fault codes or error conditions incurred at power-up. Please refer to the specific storage element manuals for such information. 3.20 Power Controller The power controller has six switched and two unswitched outlets (a total of eight outlets). All variations include an ac line filter. The power controller is 19-inch rack-mountable. The power controller serves four functions: · Controls large amounts of power from a remote source · Provides a convenient ac power distribution point for multiple units · Protects equipment from some electrical disturbances · Disconnects power (in case of overload) and provides circuit breaker protection Preparation and Installation 3-33 3.20 Power Controller ------------------------------------------------------------ WARNING ------------------------------------------------------------ High leakage current--earth connection is essential before connecting power. Verify the integrity of the earth ground terminal of the power receptacle before attaching the cabinet power controller cable and applying power. If the continuity of the terminal-to-ground cannot be verified, supplemental grounding to the cabinet system must be provided. ------------------------------------------------------------ Figure 3-11 shows the connector configurations for the power controller. Figures 3-12 and 3-13 show the front and rear views of the 874-power controller. The DECArray300 cabinet system utilizes the 874-D and 887-C models. The 887-C power controller is using IEC plugs at input and output. 3-34 Preparation and Installation 3.20 Power Controller Figure 3-11 Power Connector Configurations Preparation and Installation 3-35 3.20 Power Controller Figure 3-12 874 Power Controller, Front View 3-36 Preparation and Installation 3.20 Power Controller Figure 3-13 874 Power Controller, Rear View 3.21 External Sense Connections If external sense connections to another component are required, insert a two-pin female (socket) MATE-N-LOK connector (DIGITAL part number 12- 10821-02 with connector pin sockets A-PS-1209379-0-0) from that component into the mating male connector on the rear of the controller. (Only valid for 887-C P/C.) 3.22 Power Controller Indicators The two basic controls on the power controller are the circuit breaker and the BUS/OFF/ON switch. These and all but one of the other controls are located on the front panel of the controller. Their functions are described in Table 3-5 and in the paragraphs that follow. Preparation and Installation 3-37 3.22 Power Controller Indicators Table 3-5 Controls and Indicators ------------------------------------------------------------ Control or Indicator Function ------------------------------------------------------------ CB circuit breaker Provides overload protection for the eight output receptacles and control circuit. BUS/OFF/ON switch Controls ac power to the eight ac outlets and selects remote operation. BUS position Enables remote control of ac power via the Digital power control bus connectors. OFF position Removes ac power from the power controller output receptacles and prevents the power controller from responding to power control bus signals. ON position Applies ac power to ac outlets receptacles. Power control bus request signal is ignored. Power control bus inhibit signal is valid. EXTERNAL SENSE connector 2-pin on rear of controller (only 887-C) Isolates ac power from the output receptacles. The circuit then must be reset for normal operation by cycling the circuit breaker off and then on. Power control bus (3-pin) Provides a means of controlling the power state of a system from remote locations. A switch closure between Pins 1 and 3 will supply ac power to the output receptacles. A switch closure between Pins 2 and 3 will isolate ac power. Sequenced power control bus (3-pin) Adds a 0.5 to 2.0 second delay to the power request line (pin 1). Fuse Protects the ac bus from control circuitry overload. ------------------------------------------------------------ 3.23 BUS/OFF/ON Switch (S1) The three positions of this switch are BUS, OFF, and ON. When the circuit breaker to the power controller is ON, this switch controls to the ac outlet in the following ways: · BUS position--Enables remote control of ac power via the Digital power control bus connectors. The BUS position is intended for remote sensing of Digital power control bus instructions. This position requires the use of a remote sensing cable not shipped with the power controller. If you don't have this cable, or your application does not require the use of the Digital power control bus, leave the switch in the ON position. 3-38 Preparation and Installation 3.23 BUS/OFF/ON Switch (S1) · OFF position--Removes ac power from the power controller output receptacles and prevents the power controller from responding to power control bus signal. · ON position--Applies ac power to ac outlet receptacles.

The disk or tape drive must be handled carefully. Manual installation is not recommended. ------------------------------------------------------------ The following procedures assume that the existing Sx300 storage array is correctly installed and configured. The SF7x storage enclosure that you are installing may contain two or four RF72 disk integrated storage elements (ISEs). To determine if the SF7x contains two or four, simply look at the front of the enclosure. Remove the front bezel of the Sx300 storage array. If you can see two disk ISEs in the front of the SF7x, then the enclosure contains four ISEs (SF7x-JK variant). If you do not see two ISEs in the front of the enclosure, then that enclosure contains only two ISEs (SF7x-HK variant). If you wish to verify an enclosure that is already installed in a cabinet or array, observe the number of seven-segment displays that are lit on the OCP. If the top two displays are lit, then the enclosure contains only two RF72 disk ISEs. 5-2 Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5.1 Steps to Install This section contains several major parts. (The first part explains the steps to): · Unpack, inspect for damage, and identify parts · Determine where to install the SF7x enclosures · Read and fill out the system configuration sheet The next part explains the steps to install the SF7x enclosure itself: · Prepare the array cabinet to receive an SF7x storage enclosure · Install the supporting hardware and SF7x, and set the DSSI ID switches · Cable the SF7x storage enclosure to comply with the DSSI bus cabling conventions The last part explains the steps to: · Power up the SF7x enclosure, run the power-on self-test, and run the configuration programs · Label all cables and operator control panels · Verify the operation of the enclosure after a successful installation Follow all the steps in each of these parts in the order they are presented and do not skip any steps. When the array is to operate in a single-host configuration, remember that the enclosures SF1, SF2, SF4, SF5 operates in the through-bus mode. To be sure that the SF7x storage enclosure you are installing is in the through-bus mode after the installation is complete, observe the bottom indicator on the OCP. It should be off. SF3 and SF6 operate in the split-bus mode and require you to reconfigure their transition termination module (TTM). That same indicator should be on once the enclosure is set for split-bus mode. The procedure to accomplish this is presented later in this chapter. When the array is to operate in a dual-host configuration, remember that all enclosures operate in the through-bus mode. 5.1.1 Unpacking the SF7x Storage Enclosure Unpack the SF7x shipping container. The enclosure is shipped in an environmental barrier bag with desiccant. ------------------------------------------------------------ Note ------------------------------------------------------------ After unpacking, retain the container and all packing materials. ------------------------------------------------------------ Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5-3 5.1 Steps to Install At this time, examine the enclosure for physical damage.

Refer to Chapter 3. SF7x storage enclosures could occupy positions 1, 2, 3, 4, 5, and 6 . In split-bus mode, the following drives are part of the same DSSI bus (note that split-bus mode is supported in the single-host configuration only): 1. Four drives of SF1 with the two left drives SF3 2. Four drives of SF2 with the two right drives SF3 3. Four drives of SF4 with the two left drives of SF6 4. Four drives of SF5 with the two right drives of SF6 ------------------------------------------------------------ Note ------------------------------------------------------------ In a stripeset configuration, all SF7x storage enclosures must be in split-bus mode. Each DSSI bus is connected to two ISEs in each SF7x enclosure. One KFMSA module is required for each SF7x storage enclosure. ------------------------------------------------------------ All SF7x storage enclosures must be in through-bus mode when the Sx300 storage array is in the dual-host configuration: 1. Four drives of SF1 2. Four drives of SF2 3. Four drives of SF3 4. Four drives of SF4 5. Four drives of SF5 6. Four drives of SF6 5.1.3 Checking the System Configuration Sheet Locate the system configuration sheet. If you cannot locate this sheet or if the one that is available is either not filled out or filled out incorrectly, fill one out immediately. Refer to the KFMSA Module Installation and User Manual (EK-KFMSA-IM) for an explanation of this sheet and how to fill it out. Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5-5 5.1 Steps to Install Figures 5-1 and 5-2 show examples of the system configuration sheet filled out for an Sx300 storage array with one magazine tape subsystem. 5-6 Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5.1 Steps to Install Figure 5-1 System Configuration Sheet (Single-Host) Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5-7 5.1 Steps to Install Figure 5-2 System Configuration Sheet (Dual-Host) 5-8 Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5.1 Steps to Install Figure 5-3 System Configuration Sheet (Three-Host) Installing the SF7x Storage Enclosure in an Sx300 Storage Array 5-9 5.1 Steps to Install 5.1.4 Installation Procedure Before attempting any of the following steps, make sure that the SF7x enclosures installed in the array cabinet contain four disk ISEs. To determine if the SF7x contains two or four drives, simply look at the front of the enclosure. If you can see two drives in the front of the SF7x, then the enclosure contains four drives (SF7x-JK variant). If you do not see two drives in the front of the enclosure, then that enclosure contains only two drives (SF7x-HK variant). If you wish to verify an enclosure that is already installed and running in a cabinet or array cabinet, observe the number of 7-segment displays that are lit on the operator control panel (OCP). If the top two displays are lit, then the enclosure contains only two RF72 disk ISEs. The procedure for installing the upgrade kit is in Appendix B. This section describes the step-by-step procedures for installing an SF7x storage enclosure in Sx300 storage array. Be sure to: · Follow each step in order, and do not skip any steps · Leave sufficient room to perform the installation (approximately 1.5 meters to 1.8 meters [5 feet to 6 feet] front and rear of the array) ------------------------------------------------------------ WARNING ------------------------------------------------------------ Observe all ESD precautions and procedures. An anti static wrist strap is inside the front and rear doors. ------------------------------------------------------------ ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Do not attempt to pick up or support the SF7x by the handle in the rear of the enclosure.

Fan Visual Inspection Required. ------------------------------------------------------------ This section describes error conditions, failure influences, soft error rates, and how to run an error log code. See Table 8-4 for a list of common failures, causes, and fixes. 8.2.3 Error Conditions The word error is sometimes misunderstood. Recoverable (soft) errors are a fact of life in the tape world. There are many reasons why a soft error can occur. The tape media is not perfect, drive heads eventually wear out and start producing higher error rates, heads can become contaminated, or foreign debris can pass through the tape path. If you examine the drive error count, you will see soft errors, events, and hard errors. For example, you will receive an error if you give the wrong label name during a mount. Be sure the errors you are interpreting are indicative of a real hardware problem before swapping out the drive. 8.2.4 Common Failure Influences The tape ISE may appear to be the failing unit due to the operation being performed at the time of failure (such as back-up). However, it is important to understand that there are many factors that influence failures. Some of the more common factors are: · Defective media · Operator or user errors · Incorrect back up commands 8-14 Installation Troubleshooting 8.2 Troubleshooting the Magazine Tape Subsystem · Poor power or grounding ------------------------------------------------------------ Note ------------------------------------------------------------ Make sure that any problem you encounter is not due to the above causes before you replace the drive. ------------------------------------------------------------ Table 8-4 Common Failures, Causes, and Fixes ------------------------------------------------------------ Symptom Probable Cause Possible Fix ------------------------------------------------------------ Volume not software enabled Drive is not loaded or was unloaded by software Make sure that the yellow LED is on (tape loaded and ready for use). TK50 formatted cartridge in a TK70 drive Use correct cartridge. Bad cartridge or incorrectly written calibration tracks Try another cartridge. Bad drive or dirty head Clean head and/or replace drive. Failure to mount or initialize with new media Bad media Clean head and retry with known good media. All three LEDs blinking Drive failed self-test or detected a hard error during operation Attempt to clear error by pushing the unload button. If the error won't clear, you have a drive hardware failure or a power problem. Green LED blinking Calibration error Clear error by pressing the unload button. Try another cartridge. If the error repeats, you have a drive hardware failure or more than one bad cartridge (physically damaged or bad calibration tracks).

Common Failures, Causes, and Fixes ------------------------------------------------------------ Symptom Probable Cause Possible Fix ------------------------------------------------------------ Cartridge stuck in drive with tape on take up reel Hard drive error Attempt recovery by pressing the unload button. Drive leader runaway Mispositioned cartridge leader Inspect cartridge leader for correct position. Retire cartridge from use if leader cannot be repositioned. ------------------------------------------------------------ 8.2.5 Soft Error Rates None of the cartridges contain perfect tape. All tapes contain some number of dropouts. Although these are imperfections in the tape, the tape is not considered to be defective. The hardware and software are designed to deal with these known imperfections. Dropout testing is performed on samples of media by our vendors and meet all of the specifications of Digital Equipment Corporation. There are many variables that can cause soft errors. In fact, errors are somewhat of a misnomer since soft errors are considered to be events. In the case of soft errors, it is important to realize that no data has been lost. For a write, the data is rewritten. For a read, retries are performed. Some of the variables that create soft errors are: · Media dropouts · Temperature of media (not acclimatized) · System bus activity · Applications · Head wear · Contamination Changes in soft error rates for any particular drive and cartridge are more significant than any absolute number of soft errors. This is due to the variables described above. 8-16 Installation Troubleshooting A ------------------------------------------------------------ SF300 DSSI Storage Array Cabling Diagrams This appendix contains cabling diagrams for the Sx300 storage array variations (DSSI), in both the single-host Section A.3 and dual-host Section A.4 configurations.

Remember that Sx72 storage enclosures in positions 3 and 5 must be converted from split-bus to through-bus mode and become a D3 configuration only. ------------------------------------------------------------ ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Do not disturb any existing DSSI cables unless otherwise instructed. Do not remove any existing 42-inch DSSI cables (BC21Q-3F) between magazine tape subsystems and Sx72 storage enclosures. ------------------------------------------------------------ C-10 Converting a Single-Host Configuration to a Dual-Host Configuration C.2 Conversion Procedure Install the 70-inch DSSI cables (BC21R-5L) where necessary to complete the bus connections to the Sx300 I/O panel: 1. Connect one end of the 70-inch DSSI cable to the DSSI connector on the rear of the Sx72 storage enclosure or magazine tape subsystem. 2. Install the other end to the appropriate port on the Sx300 I/O panel. See Figure C-7. Connect the appropriate number of 108-inch DSSI cables (BC21Q-09) to all the newly installed 70-inch DSSI cables on the Sx300 I/O panel. Next, connect the other end of the 108-inch DSSI cables to the appropriate DSSI connector on the system I/O panel. ------------------------------------------------------------ Note ------------------------------------------------------------ If you have not changed the KFMSA module DSSI ID numbers in the other host system to 6, do so at this time. Do NOT attempt to connect the 108-inch DSSI cables to this host system until the DSSI ID numbers have been changed. Refer to the KFMSA Module Installation and User Manual (EK-KFMSA-IM). Refer to Table A-5 for cabling diagrams of the single-host and dual-host configurations. ------------------------------------------------------------ C.2.4 Labeling the Cables This section describes the steps to label correctly the cables for the VAX 6000 series system, the Sx300 storage array, and its Sx72 storage enclosures and tape magazine subsystems. At this point, all steps in the previous sections must be complete. Converting a Single-Host Configuration to a Dual-Host Configuration C-11 C.2 Conversion Procedure Figure C-7 Connecting DSSI Cables on the Sx300 I/O Panel C.2.4.1 Completing the System Configuration Sheet At this time, you should be ready to fill out the system configuration sheet.
