RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE The SWCC Agent V2.3 provides the ability to use SWCC from multiple hosts in a cluster. SWCC Agent V2.3 and HSOF Software V3.7 are required for this feature. 3.0 New Items Sections 3.1 through 3.3 briefly describe the new items in HSOF Software V3.7. 3.
Release Notes NOTE Although some of the above listed Devices may have been supported in previous releases, all of these Devices have been classified as “new” for the HSOF V3.7 Software Release. Please see Section 2.4 for additional information on Device Support. 3.3 Issue Resolutions This section addresses issues that occurred in a previous release of the HSOF software and have been resolved in the HSOF V3.7 release. The issues addressed by HSOF V3.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 4.0 • In a rare occurrence the HSZ40 controller may not be able to use the HSUTIL program to perform a “code load” firmware upgrade to TZ87/88/89 tape drives or any associated Automated Tape Library. In such a case the HSUTIL program refuses to perform the upgrade because it incorrectly determines that there is a tape present in the target tape drive when there is none. Please see Section 7.
Release Notes 4.3 Action for Repeated Reboot Problem Resolution Very rarely, a hardware failure might cause a controller to reboot repeatedly, preventing preferred disk devices from completing failover to the dualredundant partner. HSOF Version 3.4 contains a modification so that if the same bugcheck repeats itself three times in a ten minute period, the controller will shutdown with no restart to permit the disk devices to failover to the working controller in a dual-redundant pair. 4.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 5.2 Write-Back Cache Batteries Diagnostic testing is performed on the write-back cache batteries when the controller first initializes, and then periodically after the batteries have become fully charged. The following paragraphs clarify battery-related topics. 5.2.1 CACHE_UPS Switch Use If the SET controller CACHE_UPS switch is activated, the only action taken in the event of battery failure is to send an error message.
Release Notes 5.2.2 Cache Policy The setting chosen for SET controller CACHE_POLICY (to either A or B) affects access to RAIDsets and Mirrorsets during the initial test only and determines the cache mode the controller uses during initial test only. Initial Test begins when the controller is turned on and continues until the batteries are charged, or up to ten hours. Initial testing includes a recharge of the battery after potential discharge during shut down.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE Write-through cache mode is not a 100% guarantee of user data consistency within storagesets (RAID and mirrorsets). This is because of an inherent delay in the writing of data to the different members of these storagesets. If a power failure occurs between the writing of some members and others (an extremely narrow window), data on the various members will be inconsistent.
Release Notes 5.2.4 Extending the Life of the External Cache Batteries Occasionally, circumstances will require you to shut down your controller and restart it. If the correct steps for turning off power to an HSZ40 array controller configuration with write-back cache are not followed, there is potential for loss of data that may exist on any devices connected with them.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX CAUTION Do not turn off the power to the controller subsystem until all shutdown procedures have successfully completed. 5. If you have a dual-redundant controller configuration, shut down each controller one at a time, using the following commands: SHUTDOWN OTHER_CONTROLLER SHUTDOWN THIS_CONTROLLER If you have a non-redundant controller configuration, only the command is necessary.
Release Notes 3. Take the controller out of service by issuing the one of the following two CLI command steps. − Single Controller: SHUTDOWN THIS_CONTROLLER − Dual Controllers: SHUTDOWN OTHER_CONTROLLER SHUTDOWN THIS_CONTROLLER When the shut down completes, the controller or controllers’ green reset LED on the operator control panel (OCP) stops blinking. 4. Power off the entire storage subsystem. 5.

Before you restore power to the subsystem, remove the controller module, and the write-back cache module. Remove the battery disable jumper and replace it so it is only covering one pin, then reassemble the unit. 2.
Release Notes 5.4 Logical Block Address Does Not Match for MEDIUM ERROR The Logical Block Address (LBA) is a number used to identify a block on a mass storage device. The LBA that appears in the Information field of an Event Log (%EVL) display when the Sense Key field is MEDIUM ERROR does not agree with the LBA number contained in the Information field of the extended sense data that is sent to the host system. It is one less than the number in the extended sense data. 5.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 5.8 Saving Your Configuration The subsystem configuration should be saved to another location other than NVMEM. If the configuration is saved to another location, then the configuration will not have to be re-entered when the controller module is replaced. The method of ensuring the current subsystem configuration is saved differs depending upon whether your subsystem is a single controller (Section 5.8.
Release Notes NOTE The SAVE_CONFIGURATION switch should not be used when upgrading your hardware, and will not perform inter-platform conversions. For example, you cannot use the SAVE_CONFIGURATION switch to upgrade an HSZ40 to an HSZ70 Array Controller. Configuration information cannot be retrieved from storagesets on other HSx controllers (for example, HSD, HSJ, or prior HSOF software versions operating on HSZ controllers).
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 5.8.1.
Release Notes 5.8.1.2.2 Controller Not Factory Initialized (No Configuration Data) With this situation, the new controller does not search the devices in the subsystem for a saved configuration and the controller is not brought on-line. The CLI command: SET this_controller INITIAL_CONFIGURATION must be entered to allow the configuration saved on a storageset to be brought in. 5.8.1.2.

Release Notes 5.9 Last Failure Code 010E0110 Normal Occurrence After Upgrade When updating firmware on the controllers, the following message may appear suggesting that there is a problem with the controller or that there was an issue during the update process. The below message is normal and is not cause for alarm. Last fail code: 010E0110 Press " ?" at any time for help. %CER-HSZ_2> --13-JAN-1946 04:32:20 (time not set)-System Information Page-and Last Failure entries reset to default settings.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 6.0 Operating Constraints Paragraphs 6.1 through 6.11 describe the operating constraints for HSOF Version 3.7 software. An operating constraint is defined by the parameters within which the controller is designed to operate. Constraints of other system components, such as host adapters or host-related information, may also be described in this section.
Release Notes 6.2 SCSI Target ID Restriction for Compaq Tru64 UNIX Versions Prior to V5.0 The HSZ40 controllers can support host SCSI Target IDs between 0 and 15. However, Compaq Tru64 UNIX versions prior to V5.0 recognize SCSI Target IDs in the range 0 to 7 only. Therefore, in Compaq Tru64 UNIX versions prior to V5.0 the useable host SCSI IDs for the RA410 subsystems must be assigned within the range of 0 to 7. Please note that SCSI ID 7 is typically assigned to the host SCSI adapter.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 6.5 Device Adds, Moves, and Changes The controller maintains configuration maps of device types and locations and uses those maps for communicating with devices. If you add, move, or change devices while the controller is powered off and without changing the controller configuration first, the controller is not able to work with the changed devices when it returns to service. 6.
Release Notes 6.9 Moving Write-Back Cache Modules When moving a write-back cache module to a new environment (that is, different controller, different devices), it is very important that you perform a clean shut down of the controller and clear any data from the cache. Follow these steps to move a write-back cache module: 1. Shut down the controller and flush unwritten data from the cache module using the appropriate CLI command: SHUTDOWN THIS_CONTROLLER or SHUTDOWN OTHER_CONTROLLER 2.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE When building stripesets with drives of capacity 4 GB or greater, the largest stripeset that can be built contains 11 members. 6.11 CLONE Utility Constraints The CLONE utility cannot be used with partitioned units. When running the CLONE utility in a dual-redundant controller configuration, do not issue any CLI commands to devices that are involved in the clone operation. 7.
Release Notes The HSZ40 controller has the capability to perform firmware upgrade "code loads" to tape drives included in its storage subsystem configuration. This code load capability is manually accessed via the HSUTIL program in the controller. The code load procedure requires that there be no tape in the drive. In rare circumstances, HSUTIL in these controllers incorrectly determines that there is a tape in the target drive, and refuses to perform the firmware upgrade.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 7.2 Compaq Tru64 UNIX Patch Kits for Issue Resolution As noted in Section 3.3, a rare issue related to Bad Block Replacements in data transfers on mirrorsets is corrected by the application of both HSOF Software V3.7 and a patch kit to Compaq Tru64 UNIX V4.0x operating systems. The appropriate patch kit is identified in Table 7-1 below: Table 7-1 Patch Kits for Compaq Tru64 UNIX V4.0x Compaq Tru64 UNIX Version Patch Kit V4.0d 6 V4.
Release Notes 7.5 Only One Switch per CLI Command Recommended Certain switches within CLI commands are incompatible. To avoid problems, specify only one switch per CLI command. For example, to set both WRITEBACK_CACHE and NORUN on unit D102, use the following two commands: SET D102 WRITEBACK_CACHE SET D102 NORUN 7.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX There are two procedures that may be used to accomplish the above three steps. Compaq recommends the first procedure. 7.8.1 Using AC switch 1. Turn off AC switch after EMU alarm sounds on extended cabs. 2. Turn on AC switch on extended cabs. 3. Turn on AC switch on Master Cab. 7.8.2 Using EMU/PVA 7.9 1. On extended cabs, wait for EMU alarm to sound, turn off EMU alarm, then press and hold PVA switch until the cab shuts down. 2.
Release Notes 8.0 Documentation Additions and Corrections The following sections describe corrections to: 8.1 Array Controller HSOF Version 3.1 Configuration Manual 8.2 Array Controller HSOF Version 3.1 CLI Reference Manual. 8.3 Array Controller HSOF Version 3.1 Service Manual 8.1 Array Controller HSOF V3.1 Configuration Manual 8.1.1 Chunk Size Referring to the section titled Initialize switches in the HSZ40 Array Controller HSOF Version 3.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX CAUTION The default chunk size should be used with caution. It is imperative that you analyze the I/O transfers being used with your application to determine the proper chunk size. An improper value used as a chunk size may cause serious performance problems with the subsystem. • CHUNKSIZE=n lets you specify a chunk size in blocks.
Release Notes Large chunk sizes also tend to increase the performance of random reads and writes. It is recommended that you use a chunk size of 10 to 20 times the average request size, rounded to the closest prime number. In general, a chunk size of 239 works well for Compaq Tru64 UNIX systems with a transfer size of 16 sectors; 113 works well for OpenVMS systems with a transfer size of 8 sectors.

Please continue with controller configuration: Other controller not responding – RESET signal asserted. 8.3.
Release Notes 9.0 Software Installation CAUTION If you are operating with any Compaq Tru64 UNIX versions prior to V5.0, it is important to install HSOF software V5.7 on your controllers before upgrading to Compaq Tru64 UNIX versions 5.0 or higher. This section provides the specific procedures needed to install your HSOF V3.7 Software. The information in this section can be used in conjunction with the information found in the HSZ40 Array Controller HSOF V3.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 9.1 Single Controller Upgrade A Single Controller Upgrade is synonymous with a Shutdown Upgrade. A Shutdown Upgrade is one in which the storage device is taken off-line for the period of time that the software is being installed. Use the following procedure to upgrade the HSOF software in a non-redundant (single) controller: 1.
Release Notes NOTE After restart, the controller will not allow you to enter any CLI commands for approximately 60 seconds. This delay does not affect unit availability to the host. The delay provides time for the controller internal operations to complete before user commands can change configuration. NOTE The controller will initialize and the Reset button will flash at an approximate once per second rate when ready for operation. 7.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX Below is a description of each of the two procedures and Table 9-1 shows which procedure is necessary for the HSZ40 HSOF Software versions. Dual-Redundant Controller Rolling Upgrade: The Dual-Redundant Controller Rolling Upgrade procedure is one in which the disk subsystem does not have to be shut down to upgrade the software.
Release Notes 9.2.1 Dual-Redundant Controller Rolling Upgrade If your HSOF Software version supports a Dual-Redundant Controller Rolling Upgrade, follow the below procedures. CAUTION Prior to installing HSOF V3.7 software, it is important to first determine whether the two controllers in your dual-redundant configurations have the same or different product ID’s, this will determine the upgrade procedure you will use to continue.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 9.2.1.1 Procedure for Same Product ID’s for Dual-Redundant Rolling Upgrade 1. Establish a local connection to the controller through the maintenance port of one of the controllers (“this controller’). 2. Wait for the CLI prompt, and then shut down “other controller” by using the following command: SHUTDOWN OTHER_CONTROLLER CAUTION Before continuing, wait until the Reset button stops flashing and stays lit continuously.
Release Notes 7. Replace the ESD cover on “other controller” and push the locking pins to secure it. 8. First pass through this procedure? YES — Move the maintenance port cable from “this controller” to “other controller” maintenance port and repeat procedure from step 2 to step 8 to replace the other program card.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE Wait for the following to happen before continuing: The Reset button flashes at an approximate once per second rate and The maintenance terminal displays a message that finishes with other controller restarted. 6. Read the status of “other controller” by issuing the following command: SHOW OTHER_CONTROLLER. NOTE When the SHOW OTHER_CONTROLLER command verifies that the other controller restarted, it is safe to continue. 7.
Release Notes 9.2.1.3 Different Product ID’s and Compaq Tru64 UNIX V5.0 for Dual-Redundant Rolling Upgrade When your HSZ40 controllers with different product ID’s are configured in a system using Compaq Tru64 UNIX V5.0, it is necessary to perform some steps involving the operating system before and after controller upgrade to HSOF V3.7. 1. Determine the master controller by following the sub-steps below: a. Use the following command to view details of the devices attached to the host.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE If all the units configured on the dual controller pair are “ONLINE” to only one of the controllers (i.e. the other controller is in stand by mode), then all the devices will show only one Product ID. The controller which has the units “ONLINE” is the master controller. Go to Step 2 and perform Steps 2 through 13. It is not necessary in this case to perform Step 14. b.
Release Notes HSZ> show d600 LUN Uses ---------------------------------------------------------D600 DISK600 ... State: ONLINE to this controller Not reserved PREFERRED_PATH = THIS_CONTROLLER ... If the output shows that the unit is “ONLINE” to this controller (as is the case in this example), then THIS_CONTROLLER is the master controller. If the output shows that the unit is “ONLINE” to the other controller, then OTHER_CONTROLLER is the master controller. 2.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX NOTE Wait for the following to happen before continuing: The Reset button flashes at an approximate once per second rate and The maintenance terminal displays a message that finishes with other controller restarted. 7. Read the status of “other controller” by issuing the following command: SHOW OTHER_CONTROLLER. NOTE When the SHOW OTHER_CONTROLLER command verifies that the other controller restarted, it is safe to continue. 8.
Release Notes CAUTION Be sure to use OTHER as the qualifier in the COPY= command to properly match the Product ID’s. 13. Follow the commands in the example below to correct the device files: a. Scan the SCSI interfaces to update the operating system’s view of device changes and create new devices as necessary. NOTE Depending on the size of your configuration, the scan may take several minutes to complete. The presence of tape devices will further increase the delay to complete the scan.

NOTE Compaq does not recommend the use of the INITIALIZE SAVE_CONFIGURATION option for dual-redundant configurations. CAUTION Prior to installing HSOF V3.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX To view the product ID’s on your dual-redundant controllers, establish a local connection to the controller through the maintenance port of one of the controllers, (which becomes “this controller”). Enter the following commands and observe the resulting displays: SHOW THIS_CONTROLLER and SHOW OTHER_CONTROLLER The product ID is shown in the first characters of the display, prior to the hardware serial number.
Release Notes CAUTION Failure to shut down the controller in this step could result in problems with RAIDsets and cache when the controller is reset. CAUTION Before continuing, wait until the Reset button on the controller stops flashing (lit continuously). This indicates that unwritten data is flushed from the cache module. 5. Remove the PCMCIA program card ESD cover from the controller. 6.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 8. Replace the ESD cover on the controller, pushing the locking pins to secure them in place. 9. Mount the storage units on the host. Resume I/O activity to the controller. 10. Repeat 5 through 9 for the second controller. 11. After you complete all of the above steps on both controllers, put the controllers back into dual-redundant (failover) mode by entering the following command: $ SET FAILOVER COPY=CONFIGURATION_SOURCE 9.2.2.
Release Notes NOTE The controller will initialize and the Reset button will flash at an approximate once per second rate when ready for operation. 7. Press and hold the Reset button while inserting the new program card. Release the button after the new card is inserted. NOTE After restart, the controller will not allow you to enter any CLI commands for approximately 60 seconds. This delay does not affect unit availability to the host.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX 9.2.2.3 Different Product ID’s and Compaq Tru64 UNIX V5.0x for Dual-Redundant Shutdown Upgrade When your HSZ40 controllers with different Product ID’s are configured in a system using Compaq Tru64 UNIX V5.0, it is necessary to perform some steps involving the operating system before and after controller upgrade to HSOF V3.7. 1. Determine the master controller by following the sub-steps below: a.
Release Notes NOTE If all the units configured on the dual controller pair are “ONLINE” to only one of the controllers (i.e. the other controller is in stand by mode), then all the devices will show only one Product ID. The controller which has the units “ONLINE” is the master controller. Go to Step 2 and perform Steps 2 through 12. It is not necessary in this case to perform Step 13. b.

Release Notes 10.0 Possible Problem Identified Read this section if you initialized a JBOD disk using the SAVE_CONFIGURATION switch on an HSZ40 controller running HSOF Version 2.7, and then moved the disk to your HSZ40 controller subsystem. There is a remote possibility that some disks attached to HSZ40/20/SWXRC controllers and the solution products containing them (RA410, SC4200/4600, etc.) might have a problem in the structure of the on-disk file system.
RAID Array 410 HSZ40 HSOF Software Version 3.7 for Compaq Tru64 UNIX Various configuration events cause the controller to write the configuration data to save configuration area. If the controller overwrites file system data, the results vary depending on the platform operating system and the application.
Release Notes 10.2 5. Compare the total block size obtained from the "show device" command with the block size capacity obtained in step 3. 6. If the reported sizes are different, this disk is at risk for the problem. See the "Solution" section of this appendix for the recovery procedure. Solution If you are using the INITIALIZE SAVE_CONFIGURATION command to initialize JBOD disks under HSOF Version 27Z, be sure to initialize the disk with the platform file system before rebooting the controller.
