It is a high-performance Enhanced Intelligent Peripheral Interface (IPI-2) disk subsystem. This subsystem consists of a low profile desktop enclosure with 5.25 inch IPI-2 disks manufactured by Seagate Technology, Inc. and either a TURBOchannel controller or Futurebus+ controller manufactured by GENROCO International, Inc. The desktop enclosure can accommodate up to two three-gigabyte (Gb) drives. Up to four two-drive enclosures (eight drives maximum) can be daisy chained to a single controller. In this document, information that applies to the TURBOchannel and the Futurebus+ disk controller will be referred to as the IPI-242T/F disk controller. Information that applies only to the TURBOchannel disk controller will be referred to as the IPI-242T disk controller and information that applies only to the Futurebus+ disk controller will be referred to as the IPI-242F disk controller. Introduction 1-1 Introduction 1.2 IPI-2 Overview Users of high-performance systems are limited in terms of disk performance by the overhead the Small Computer System Interface (SCSI) has in supporting disks, tapes, printers, scanners, and so forth. The enhanced IPI-2 interface is a dedicated interface that supports a single device type and improves system I/O capabilities. The interface is the communications channel between the controller and the drive. It provides high-speed transfer of commands, responses, and data between the controller and the drive. IPI-2 is appropriate in either workstation or server environments where sustained disk throughput is required. From the host operating system's point of view an IPI disk emulates an RA-series device using Mass Storage Control Protocol (MSCP). 1.3 Minimum Operating System Versions The VELOCITOR storage subsystem requires the following minimum operating system versions: · ULTRIX Version 4.2 · OSF/1 Version 1.2 1-2 Introduction 2 ------------------------------------------------------------ Technical Description 2.1 VELOCITOR Storage Subsystem The following is an overview of the major components of the VELOCITOR storage subsystem. 2.1.1 TURBOstor IPI-242T/F Disk Controller The GENROCO TURBOstor IPI-242T disk controller occupies a single TURBOchannel slot in the host computer. The GENROCO TURBOstor IPI-242F disk controller occupies a single Futurebus+ option slot in the host computer. For specific details refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual. This manual provides an overview on installing and configuring the controller into the host computer, and installing and performing software setup. 2.1.2 Enhanced IPI-2 Disk Drives The Enhanced IPI-2 Seagate 5.25-inch disk drive features include read/write buffers, zone mapped disk drives, parallel heads, and drive error code correction (ECC). For further details refer to the Seagate ST43200K User 's Manual. 2.1.3 Desktop Storage Enclosure This enclosure is part of the Digital SZ16 storage expansion series, utilizing the same power supply and low profile enclosure. These enclosures have been modified to accommodate up to two IPI-2 disk drives. The internal cables link the drive or drives, in series, to the enclosure rear panel. Technical Description 2-1 Technical Description 2.1.4 External Interface Connections The storage expansion box rear panel has four IPI interface connectors: · Port A IPI-2 IN (male) · Port A IPI-2 OUT (female) · Port B IPI-2 IN (male) · Port B IPI-2 OUT (female) The maximum total IPI-2 cable length is 50 m (164 ft). In a typical single port application a shielded 50 conductor cable is connected from the IPI-242T/F controller to the A IN port on the rear of the enclosure. The bus is terminated by installing an IPI-2 terminator on the A OUT connector. Terminators should be installed on all unused connectors. 2.1.5 Dual Porting Each disk drive has two independent ports that can be connected to two separate controllers. These dual ports allow a disk to be shared between two disk controllers, thus enabling a second data path to be used. This is a robust configuration, because the two data paths are electrically and logically independent. 2-2 Technical Description Technical Description 2.2 Specifications This section provides specifications for the VELOCITOR storage subsystem. For the TURBOstor controller and the Seagate ST43200K disk drive specifications refer to the related documentation listed in the Preface. 2.2.1 Physical Specifications Table 2-1 and Table 2-2 provide the physical specifications.

Set Up and Installation 3-5 Set Up and Installation Table 3-2 Dual Ported Disk Drive Jumpers ------------------------------------------------------------ Jumper Description Location State ------------------------------------------------------------ Master/Slave J12 Out Local/Remote J12 In Read/Write Diagnostics I/O board In Background Sweeps I/O board Out Sweep on Seek J12 In Write Enable J10 Out Disable Port A J10 Out Disable Port B J10 Out ------------------------------------------------------------ 3. Connect the male end of the data cable to the IPI-242T/F disk controller and the female end to the Port A IN on the back of the VELOCITOR storage subsystem. 4. Connect the male end of the other data cable to the second IPI-242T/F disk controller and the female end to the Port B IN. See Figure 3-3. 5. If there is only one storage subsystem enclosure or it is the last storage subsystem, terminate both the Port A and B OUT ports on the back of the VELOCITOR storage subsystem with the supplied terminators. If an additional enclosure is to be added, prepare the enclosure as described above for dual porting. Then take the male end of the data cable and connect it to the Port A OUT of the first enclosure and connect the female end to the Port A IN of the second enclosure. Repeat this procedure for Port B and then terminate. See Figure 3-3 for an illustration of two dual ported expansion enclosures. 3-6 Set Up and Installation Set Up and Installation Figure 3-3 Dual Ported Desktop Enclosures CS­10153 Set Up and Installation 3.7 Powering On/Off The enclosure On/Off switch is illustrated in the off (O) position in Figure 3-4. Configuration changes and external cable connections must be made prior to turning on power to the desktop storage subsystem(s). Turn on power to the subsystem(s) before turning on power to the host system. The storage subsystems are jumpered to allow a sequenced delay for spindle spin up after power on. Power is applied to each drive 10 seconds after the previous drive in the sequence has received power. Each drive takes approximately 30 seconds (maximum) to spin up after it receives dc power. Figure 3-4 On/Off Switch CS­10154 Set Up and Installation 3.8 Software Setup The subsystem software driver is supplied on a CD-ROM or other media for the Alpha AXP OSF/1 or ULTRIX operating system. Refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual for information on how to: · Install TURBOstor software · Modify the configuration file · Build a new OSF/1 or ULTRIX kernel · Partition the disk(s) · Create an OSF/1 or ULTRIX file system ------------------------------------------------------------ Caution ------------------------------------------------------------ Read the TURBOstor Software Installation & Setup chapter in the appropriate user 's manual completely before performing the software installation and setup. Pay particular attention to the section on partitioning disk(s) and building file systems to prevent system or performance problems. Failure to follow the instructions could result in system errors or loss of performance if the disks are incorrectly partitioned. ------------------------------------------------------------ ------------------------------------------------------------ Caution ------------------------------------------------------------ Back up your system disk before installing the IPI-242T/F driver. ------------------------------------------------------------ 3.9 EEPROM Parameters There are several parameters that can be changed by using the TURBOstor Offline Maintenance Utility (OMU). Refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual for instructions on using OMU. One parameter has been factory preset and is different from the default EEPROM values: data block size (default - 512, factory setting - 4096). Set Up and Installation 3-9 Set Up and Installation ------------------------------------------------------------ Caution ------------------------------------------------------------ If you use the OMU to check the parameters that are set for your device, do not answer "yes" to the query "Set default parameters (y/n)." Otherwise you will reset all the EEPROM parameters back to the default settings, including the data block size and the cache size. ------------------------------------------------------------ 3.10 TURBOraid Disk Striping The IPI-242T/F supports TURBOraid controller-based disk striping, providing controller-based RAID 0 functionality for your IPI system. TURBOraid controller- based striping improves I/O performance by interleaving pairs of disks, making them appear to the operating system as a single, faster disk with twice the capacity. The operations of TURBOraid striping are completely transparent to the user. TURBOraid striping is enabled by setting an EEPROM parameter. Refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual for more information on TURBOraid striping. 3.11 TURBOraid Disk Shadowing The IPI-242T/F supports TURBOraid controller-based disk shadowing, providing controller-based RAID 1 functionality for your IPI system. TURBOraid controller- based disk shadowing automatically maintains a duplicate copy of the data from one disk on another disk, providing greater data availability, and in some cases, improved I/O performance. TURBOraid shadowing is enabled by setting an EEPROM parameter. Refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual for more information on TURBOraid shadowing. 3-10 Set Up and Installation 4 ------------------------------------------------------------ Maintenance and Problem Solving 4.1 TURBOstor Offline Maintenance Utility (OMU) Offline maintenance functions such as drive formatting, setting the EEPROM parameters, and diagnostic functions can be performed using the IPI-242T/F controller TURBOstor Offline Maintenance Utility (OMU). The IPI-242T/F controller uses a microcode program in firmware to perform these functions. ------------------------------------------------------------ Caution ------------------------------------------------------------ Always back up your disks before performing any function in the Drive Formatting submenu. ------------------------------------------------------------ 4.1.1 Drive Formatting The drives in the VELOCITOR storage subsystem are preformatted to 4096 bytes per sector and typically do not require reformatting. ------------------------------------------------------------ Note ------------------------------------------------------------ All drives connected to a controller must be formatted using the same data block size. Drives in a dual-ported configuration must also be formatted using the same data block size. ------------------------------------------------------------ Maintenance and Problem Solving 4-1 Maintenance and Problem Solving For information on formatting a drive refer to the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual. In addition, the following functions are available under the formatting menu: · Display media defects · Process media defects · Media check patterns · Data copy · Data compare · Display bad block table (RCT) · Display bad block replacements · Format/test multiple drives · Replace LBN ------------------------------------------------------------ Caution ------------------------------------------------------------ Data is overwritten during reformatting. Always back up data before reformatting the disk. ------------------------------------------------------------ 4.1.2 Other Maintenance Operations Other functions that can be performed using the OMU are: · Display drive characteristics · Seek test · Data rate test · Change EEPROM parameters · Spin-up drive · Spin-down drive These options are described in the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual. 4-2 Maintenance and Problem Solving Maintenance and Problem Solving 4.2 Problem Solving To ensure that the installation was performed correctly, perform the quick operational check as described in the TURBOstor IPI-242T IPI Disk Controller User 's Manual or the TURBOstor IPI-242F IPI Disk Controller User 's Manual. Further troubleshooting and diagnostic information is also documented. In addition, the following list contains some basic checks that can be done: 1. Ensure that the drive enclosures are correctly cabled in series, with the controller at one end and a terminated enclosure at the other. 2. Secure all cables and terminators with screw-posts. 3. Turn power on to the drive enclosure(s) before turning power on to the system. 4. Verify that the IPI-242T/F controller data block size parameter matches the format on the drive. 5. Ensure that all disk drives have unique IDs between 0-7. If the above steps or the quick checks do not work, contact your local Digital Customer Service Center for support on your VELOCITOR storage subsystem. 4.3 Preventive Maintenance, Cleaning, and Repairs 4.3.1 Preventive Maintenance The VELOCITOR storage subsystem is designed to be preventive maintenance free. 4.3.2 Cleaning Periodically, the ventilation should be checked to ensure that air is being exhausted through the enclosure side. If the enclosure appears dusty, then the outside can be cleaned with an antistatic foam cleaner. Do not allow any liquid to enter the unit. Always spray a cleaner onto the applying cloth. In extremely dusty conditions, vacuum the enclosure internals. 4.3.3 Repairs Repairs should be performed by trained service personnel.

Upgrade the storage expansion box as follows: 1. Locate and remove the two angled mounting brackets, four screws, and four washers already mounted inside the expansion box in drive position 1. See Figure A-2. 2. Attach the mounting brackets to the drive by aligning the slots on the longer side of the mounting brackets to the higher mounting holes on the drive sides. Fasten with four 6-32 screws and washers. 3. Align and mount the drive with four 6-32 screws and washers in the storage expansion enclosure in drive position 1 with the same orientation as the existing drive.

Connect cables as follows (see Figure A-3): a. Connect the dc power cable to connector J15. b. Connect the drive ID select cable to connector J10 with the orientation shown in Figure A-3. c. Connect the drive stub adapter cables, supplied with the upgrade kit, to ports A (J31) and B (J32) of the drive. d. Connect the other end of the Port A drive stub adapter cable to the internal IPI data cable that is connected to Port A of the existing drive. Repeat this step for Port B. 5. Verify all drive jumper settings. (See Table 3-1 or Table 3-2 for single or dual ported settings, respectively.)
