Figure 1-2 SW300 Components (Cabinet Removed for Clarity) 1.3.1 AC Power Entry Controller The two ac power entry controllers provide the system on/off switch, ac power to all power supply SBBs, noise filtering, surge suppression, and electromagnetic interference (EMI) filtering. In the SW300 enclosure, an auxiliary ac power source and a second ac power entry controller supply ac power to a second power supply SBB in each shelf. If the primary ac power source or ac power entry controller A fails, the shelf 1-4 Introduction to the SW300 Enclosure remains powered by the ac power entry controller B. As shown in Figure 1-3, this configuration provides complete power redundancy to the shelf 's devices. The ac power entry controller A provides power to the four power supply SBBs on power supply bus A. This is the minimum power configuration (4+0) for the system. The power supply SBB located at the top of power supply bus B provides power for 4+1 redundancy. For 4+4 redundancy, the ac power entry controller B provides power to the four power supply SBBs on power supply bus B. See Chapter 3 for additional information on power configurations. Figure 1-3 SW300 Power Configuration 1.3.2 The High-Availability Storage Subsystem Fault Bus The HS-series controllers use the StorageWorks high-availability storage subsystem fault bus to monitor certain fault conditions in the subsystem's shelves and enclosure. The fault bus, which is not a FRU, offers the following features: · Notification when a device is physically removed from or inserted into the storage subsystem · Notification of a failure associated with a device shelf and enclosure (for example, a shelf blower) · Visual indication of bus/device status, facilitating fault isolation by the user The high-availability storage subsystem fault bus consists of four signals added to each SCSI device port as described in the StorageWorks Solutions High- Availability Storage Subsystem Fault Bus OEM Engineering Specification. The controller uses the fault bus signals in the manner described in the specification. Introduction to the SW300 Enclosure 1-5 1.3.3 Environmental Monitor Unit (EMU) The EMU provides increased protection against catastrophic subsystem faults. The SW300 enclosure has two EMUs to provide complete system redundancy. If one EMU should fail, the other continues to monitor all system functions. The EMU works with the controller to warn the user of various types of existing or impending subsystem failures. The controller responds to such conditions by displaying error messages to the operator via the maintenance terminal and host interfaces. At the same time, it controls the warning light emitting diodes (LEDs) on the HS controller operator control panel (OCP) and the storage devices. The EMU reports faults by turning on status LEDs on the SW300 front panel. The EMU has a selectable audible alarm switch on the front panel: · In the up (enable) position, the alarm is activated and produces an audible signal whenever a fault condition occurs. · In the down (disable) position, the alarm is deactivated. The EMU performs the following specific functions: · Monitors and controls the cabinet blowers--The EMU monitors the FAN_OK signals coming from each of the eight blowers. If any blower malfunctions (that is, its speed goes below a setpoint), the EMU turns all of the other blowers up to high speed. This condition also generates a fault signal: ------------------------------------------------------------ Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 ------------------------------------------------------------ Turns on an LED on the EMU that identifies the defective blower ------------------------------------------------------------ Turns off the SHELF_OK signal ------------------------------------------------------------ Activates the audible alarm The EMU monitors the FAN_INPLACE signals originating from each bank of four blowers and detects if a blower is not installed or connected. If a blower is not installed or connected, the EMU turns all of the other blowers up to high speed. This condition also generates a fault signal: - Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 - Turns on a bank of LEDs on the EMU (thereby identifying the bank with the missing blower) - Turns off the SHELF_OK signal - Activates the audible alarm · Monitors the power supplies--The EMU monitors the POWER_OK signals originating from all power supply SBBs. The EMU performs the following actions if less than four power supply SBBs are functioning properly: - Turns off the SYSTEM_POWER_OK signal going from the EMU - Turns off the System OK (green) LED on the EMU - Turns on the Shelf Fault (amber) LED on the EMU - Turns off the System OK (green) LED located on the upper right corner on the front of the SW300 - Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 1-6 Introduction to the SW300 Enclosure - Turns off the SHELF_OK signal - Activates the audible alarm - Resets the host controller(s) If one power supply SBB fails, but four or more power supply SBBs are still functioning, the EMU generates a fault condition and performs the following actions: - Turns on the Shelf Fault (amber) LED on the front of the EMU - Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 · Senses cabinet temperature--The EMU senses two different temperatures: warning and reset state. Warnings take place when the temperature is above 35°C (95°F). The EMU generates a fault condition and performs the following actions: - Turns on the Temperature (amber) LED on the EMU - Turns on the Fault (amber) LED located on the upper right corner on the front of the SW300 - Turns the dual speed blowers up to high speed The SW300 is held in a reset state when the temperature is above 50°C (122°F).

These slots provide the mechanical mounting, power, and signal interfaces for the units they house. This assembly allows for the mounting of two controllers to provide redundancy. ------------------------------------------------------------ Note ------------------------------------------------------------ This manual covers minimal controller functionality. All other information on controllers, such as a list of storage devices controlled by individual controllers, warm swap procedures, and controller-terminal connections is covered in the specific controller documentation. ------------------------------------------------------------ The HS-controllers provide a connection between a host computer and an array of SCSI-2 compatible storage devices. A terminal is plugged into the controller during subsystem installation to set initial controller parameters. See the StorageWorks Array Controllers HS Family of Array Controllers User 's Guide for details. The SW300 can be configured for controller dual redundancy. See the HS controller documentation to determine warm swap procedures for each controller. As shown in Table 1-2, the SW300 enclosure supports the following HS controllers: Table 1-2 HS Controllers ------------------------------------------------------------ Controller Interface Storage Device Buses ------------------------------------------------------------ HSD30 Digital standard system system interconnect (DSSI) Six 8-bit single-ended SCSI-2 HSJ30 Computer Interconnect (CI(TM)) bus Six 8-bit single-ended SCSI-2 HSJ40 CI bus Six 8-bit single-ended SCSI-2 HSZ10 Fast, wide, differential SCSI Five 8-bit single-ended SCSI-2 HSZ15 Fast, wide, differential SCSI Five 8-bit single-ended SCSI-2 HSZ40 Fast, wide, differential SCSI Six 8-bit single-ended SCSI-2 ------------------------------------------------------------ For a list of the storage devices controlled by individual controllers, see the StorageWorks Array Controller Operating Firmware Release Notes. 1-8 Introduction to the SW300 Enclosure 1.3.5 Dual Speed Blowers As shown in Figure 1-4, the SW300 enclosure has eight rear-mounted blowers that pull air from the front of the cabinet to the rear. Connectors on the backplane provide the +12 V dc of power to operate the blowers. Logic signals allow the status of the shelf blowers to be monitored by the EMU. All operational blowers are turned up to high speed when the following conditions exist: · If a high warning temperature condition is detected by the EMU · If a blower is defective or removed · If a blower 's speed falls below the set point Figure 1-4 Dual Speed Blowers (Cabinet Removed for Clarity) Introduction to the SW300 Enclosure 1-9 1.3.6 Power Supply SBBs ------------------------------------------------------------ Note ------------------------------------------------------------ The BA35X-HA power supply is not supported in the SW300 enclosure. ------------------------------------------------------------ The power supply SBB (BA35X-HD), shown in Figure 1-5, converts ac input from the ac power entry controller to +5 V dc and +12 V dc for use by the SW300 components. The SW300 enclosure provides connections for up to eight power supply SBBs. A minimum of four operable power supply SBBs is required for system operation. The SW300 enclosure is designed for 4+1 redundant power supply. In this configuration, the four power supply SBBs on power supply bus A are provided with additional redundancy by the power supply SBB located in the top shelf of power supply bus B. This power supply SBB is connected to the black power cord. Power is provided to the SW300 enclosure until such time as there are less than four operating power supply SBBs. If this condition is reached, the SW300 enclosure will be held in a reset state. With 4+4 full redundant power supplies, the SW300 enclosure can sustain multiple power supply faults. When 4+4 full redundant power supplies are used, input power may be connected to two separate utility power grids. In this configuration, the power supply SBBs on power supply bus A are connected to black power cords. The power supply SBBs on power supply bus B are connected to grey power cords. See Chapter 3 for further discussion of power configurations.

The SW300 enclosure provides space for 24 3½-inch SBBs, 8 5¼-inch SBBs, or combinations of each. A 3½-inch SBB occupies one slot in a shelf. A 5¼-inch SBB requires three slots in a shelf. The disk drive SCSI bus address for 5¼-inch SBBs is usually assigned based upon the shelf backplane connector but also can be assigned manually in some SBBs. See the StorageWorks Solutions Shelf and SBB User 's Guide. The disk drive SCSI bus address for 3½-inch SBBs is usually assigned based upon the shelf backplane connector. Not all storage devices are supported by each type of HS array controller. See the current HS array controller model-specific software product descriptions (SPDs) and release notes for detailed information. For a list of the various StorageWorks storage devices that can be utilized in the SW300, see the StorageWorks Solutions Configuration Guide.

The blowers will operate at high speed to reduce the temperature. ------------------------------------------------------------ Shelf Fault (amber) LED ON Has one or more of the following faults: · A power supply SBB has failed (verify if any individual power supply SBB LEDs are off to confirm) · Fewer than four power supply SBBs are operational. ------------------------------------------------------------ 4-4 Error Analysis and Fault Isolation 4.4 HS Array Controller LEDs and Fault Notification The operator control panel (OCP), normal operation, and fault notification are discussed using a typical HSZ40 controller for reference. 4.4.1 HSZ40 Operator Control Panel The HS controller OCP contains the following: · One reset button (//) with an embedded green LED · One button per SCSI port · Six amber LEDs 1 Figure 4-3 shows the HSZ40 controller OCP. Buttons and LEDs serve different functions with respect to controlling the SCSI ports and/or reporting fault and normal conditions. Button and LED functions are discussed in the following sections. Figure 4-3 HS Controller Operator Control Panel 4.4.2 HSZ40 Normal Operation The reset (green) LED (//) reflects the state of the controller and the host interface. Once controller initialization completes and its firmware is functioning, the green button constantly flashes. Pressing the green button during this normal operation resets the controller. ------------------------------------------------------------ 1 The HSJ-series controller has the amber LEDs embedded in the port buttons. Error Analysis and Fault Isolation 4-5 Under normal operation, the amber LEDs indicate the state of the respective SCSI-2 buses. When the devices on the buses are functioning correctly, the amber LEDs will not be lit or flashing. Pressing one of the port buttons at this time will light its corresponding amber LED and quiesce its SCSI-2 port. A port must be quiesced to remove or warm swap a device on the SCSI-2 bus for that port. For further information regarding StorageWorks building block (SBB) warm swaps, see the StorageWorks Array Controllers HS Family of Array Controller Service Manual. 4.4.3 HSZ40 Fault Notification The OCP LEDs display information when the HS controller encounters a problem with a device configuration, a device, or the controller itself. For definitions of error codes, see the StorageWorks Array Controllers HS Family of Array Controller Service Manual. 4.5 Storage Device SBB LEDs and Fault Notification The storage device SBBs come in either a 3½-inch or a 5¼-inch as shown in Figures 4-4 and 4-5 respectively. Each storage SBB has two LEDs that display the SBB's status. These LEDs have three states: on, off, and flashing. · The upper (green) LED is the Device Activity LED and is on or flashing when the SBB is active. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Removing a storage SBB when the upper LED is on or flashing can cause the loss or corruption of data. ------------------------------------------------------------ · The lower (amber) LED is the Device Fault LED and indicates an error condition or configuration problem when it is either on or flashing. 4-6 Error Analysis and Fault Isolation Figure 4-4 3½-Inch Storage SBB DEVICEðTx FAULTðTx (AMBER)ðTX ------------------------------------------------------------ ------------------------------------------------------------ DEVICEðTx ACTIVITYðTx (GREEN)ðTX CXO-3671A-PHðTX ------------------------------------------------------------ · When the upper LED is on, all the power supplies on its power bus are functioning properly. · When the upper LED is off, at least one of the power supply SBBs on its power bus is not functioning properly. · When the lower LED is off, either there is an input power problem or the power supply is not functioning.

You must determine the appropriate replacement method prior to replacing a power supply SBB. The light emitting diodes (LEDs) on the front of the SBB indicate the status, either operational or non-operational. · For power supply SBBs, the hot-swap method can be used providing that device is not active (that is, both LEDs are off). · The cold-swap method is normally used during initial installation. The power is removed from the enclosure assembly and all devices are inactive. None of the devices is operational until the power is restored. Use the following procedure to replace a power supply SBB: ------------------------------------------------------------ CAUTION ------------------------------------------------------------ The power supply SBB can be damaged if dropped. When removing or replacing a power supply SBB, always use both hands to support its weight. To prevent electrostatic discharge (ESD) damage to an SBB, do not touch the SBB connector. ------------------------------------------------------------ 1. Disconnect the power cord from the front of the power supply SBB. 2. Make sure that both LEDs on the power supply SBB are off. 3. As shown in Figure 5-1, press the two mounting tabs together to release the power supply SBB from the shelf. Removal and Installation Procedures 5-1 4. Use both hands and pull the power supply SBB out of the shelf. Figure 5-1 Removing a Power Supply SBB (Cabinet Removed for Clarity) 5.2 Installing a Power Supply SBB Use the following procedure to install a power supply SBB: 1. Insert the replacement power supply SBB into the guide slots and push it in until it is fully seated and the mounting tabs engage the shelf. 2. Connect the power cord to the power supply SBB. 3. After input power is applied, observe the power supply SBB LEDs to make sure the power supply is functioning properly. Both status LEDs should be on. 5.3 SBB Warm Swap An SBB warm swap involves quickly removing and replacing a disk drive, tape drive, or other storage SBB. SBBs can be removed safely without taking the system or controller off line or adversely affecting activity on the rest of the system. Using warm swap also preserves data integrity. However, before removing a device, either the controller or the operator must determine that the swap is necessary. The SBB warm swap procedure also can be used to add a device to an empty shelf slot. · The controller determines that a device is bad by trying to access the device, receiving no response from the device, or detecting excessive errors from the device. · The operator decides to remove a device by examining the controller 's operator control panel (OCP) codes, the SBB LEDs, system messages, or system error log information. 5-2 Removal and Installation Procedures 5.4 Removing a Storage Device SBB ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Warm swap supports removing and replacing only one SBB at a time. Should another SBB need to be swapped, the entire warm swap procedure must be repeated. The steps in this section must be followed in their exact order to be sure of the following: · Preserve data integrity (especially for devices with older SCSI interface designs). · Reduce chances of making a port unusable for a long period, which can render several devices inaccessible. · Prevent the controller from performing unpredictably. ------------------------------------------------------------ Removing or replacing a storage SBB is reported to the controller or host by the C_SWAP signal. The transition of this normally high signal to a low signal indicates that a storage SBB has been removed or inserted. Upon receipt of this signal, the controller can respond as described in Table 5-1. Table 5-1 Controller Response to the C_SWAP Signal ------------------------------------------------------------ Replacement Action Controller Response ------------------------------------------------------------ Removing a storage device when data is not being transferred None Removing a storage device during a data transfer operation Verify data validity Installing a storage device Begin the storage device configuration process ------------------------------------------------------------ Use the following procedure to replace a storage device SBB: ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Be sure that the replacement device is the same model as the one being replaced unless the system is reconfigured. Be sure the Device Activity (green) LED on the SBB is out. Removing a storage device SBB when the upper LED is on or flashing can cause the loss or corruption of data. To prevent electrostatic discharge (ESD) damage to an SBB, do not touch the SBB connector. ------------------------------------------------------------ 1. The device must be dismounted from the host before proceeding. (For example, enter the DISMOUNT command if using the Open VMS operating system.) See the operating system documentation for procedures necessary for dismounting a device. Removal and Installation Procedures 5-3 2. Quiesce the SBB's port by pressing and holding the controller port button for the SBB. Continue holding the button until all controller amber OCP LEDs light. ------------------------------------------------------------ Note ------------------------------------------------------------ Only one port can be quiesced at any time. If the button is not held long enough, or multiple buttons are pushed in quick succession, all buttons are ignored (no ports are quiesced). The button must be pressed and held again to quiesce the port. ------------------------------------------------------------ 3. Wait until the chosen controller port LED flashes alternately with the other port LEDs (this indicates I/O has stopped). The alternating pattern flashes for approximately 30 seconds, during which time the SBB can be removed. If the pattern does not appear after a minute or two, another shelf is asserting a fault signal that prevents any quiesce function on this controller. To correct the problem, the suspect shelf must be located and all devices must be removed. 4. To remove the SBB, press its two mounting tabs together to release it from the shelf, and pull it out using both hands (see Figure 5-2). While the controller OCP LEDs are flashing, any remaining SBBs on the quiesced port will flash their status LEDs. Figure 5-2 Removing a Storage Device SBB (Cabinet Removed for Clarity) ------------------------------------------------------------ Note ------------------------------------------------------------ The length of time required for I/O to stop can vary from zero seconds to several minutes, depending on load, device type, and cache status. ------------------------------------------------------------ 5-4 Removal and Installation Procedures When the SBB is removed, the LED pattern on the controller OCP changes to solid amber, and normal operation on the ports resume. At this time, the removed SBB's port LED on the controller OCP turns on. The LED stays on until the SBB is returned to its slot or until another SBB is inserted in the slot. The remaining port LEDs on the controller OCP turn off. 5.5 Installing a Storage Device SBB Use the following procedure to install a storage device SBB: ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Use a replacement device of the same type as the removed device. Otherwise, subsystem failures such as the establishment of stripesets can occur. ------------------------------------------------------------ 1. Quiesce the SBB's port by pressing and holding the port button on the controller. Continue holding the button until all controller amber OCP LEDs are on. ------------------------------------------------------------ Note ------------------------------------------------------------ Only one port can be quiesced at any time. If the button is not held long enough, or multiple buttons are pushed in quick succession, all buttons are ignored (no ports are quiesced). The button must be pressed and held again to quiesce the port. ------------------------------------------------------------ 2. Wait until the chosen controller port LED flashes alternately with the other port LEDs (this indicates I/O has stopped). The alternating pattern flashes for approximately 30 seconds, during which time the SBB can be inserted. If the pattern does not appear after a minute or two, another shelf is asserting a fault signal that prevents any quiesce function on this controller. To correct the problem, the suspect shelf must be located and all devices must be removed. While the controller OCP LEDs are flashing, any SBBs on the quiesced port will flash their status LEDs. ------------------------------------------------------------ Note ------------------------------------------------------------ The length of time required for I/O to stop can vary from zero seconds to several minutes, depending on load, device type, and cache status. ------------------------------------------------------------ 3. Holding the SBB in both hands, insert it into the guide slots and firmly push it into the shelf until the mounting tabs snap into place. 4. Observe the status LEDs for the following indications: the Device Activity (green) LED is either on, flashing, or off. The Device Fault (amber) LED is off. 5. Restore the device to the configuration.
