ACS Enhancements and Fixes ACS Enhancements and Fixes This section covers: ■ New CLI Commands and Switches, page 10 ■ Other Enhancements, page 18 ■ ACS Fixes, page 23 New CLI Commands and Switches Table 1 on page 10 lists and describes new Command Line Interface (CLI) commands included in this release of ACS V8.8-1. Table 1: New CLI Commands and Switches Item CLI Command or Switch Description and Background 1.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 4. CLI Command or Switch HOST_REDUNDANT NOHOST_REDUNDANT Description and Background Turns on and off the capability to redirect the host to the redundant unit copy for the original requested unit data after the controller is unable to submit data from the original unit to the host. This switch is used in conjunction with the SET unit-number command.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 5. CLI Command or Switch DESTROY_MBR Description and Background Removes the 8 MB partition from a presented LUN and destroys the master boot record (MBR) present on new or replacement spares, HP-manufactured disk drives. This switch is used in conjunction with the INITIALIZE command.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 6. CLI Command or Switch FAKE_PR Description and Background Note: Use the FAKE_PR switch for maintenance or recovery operations only. If set on a unit, allows the controller to signal to host systems implementing persistent reservations that persistent reservations are lost. (Lost persistent reservations can occur as a result of mirrored cache reconfiguration or maintenance activities, such as cache module replacement.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 7. CLI Command or Switch REINITIALIZE container-name Description and Background Invokes maintenance actions against initialized containers and modifies container metadata. Also modifies the prior device initialization or acts upon storageset attributes before its initialization. Note: Issue this command with a valid switch.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item CLI Command or Switch Description and Background 8. REINITIALIZE container-name TURNSAVEOFF Disables the option to save configuration information for devices that were initialized with the SAVE_CONFIGURATION switch. 9.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 10. CLI Command or Switch REINITIALIZE container-name SPECIAL_FUNCTION_ONE= PARTITION Description and Background Directs the controller to set the partition flag bits on all devices in a container and establishes the container as a partitioned container. This command can only be used with RAIDset containers. Caution: Ensure that the container was previously initialized as a partitioned container before using this command.
ACS Enhancements and Fixes Table 1: New CLI Commands and Switches (Continued) Item 11. CLI Command or Switch REINITIALIZE container-name SPECIAL_FUNCTION_ONE= NOPARTITION Description and Background Directs the controller to reset the partition flag bits on all devices in a container and establishes the container as a non-partitioned container. This command can only be used with RAIDset containers.
ACS Enhancements and Fixes Other Enhancements Host Connection Maximum and New Instance Code, 43036A64 If you exceed the maximum number of host connections (96), ACS now notifies you of the discrepancy. A new instance code, 43036A64, is issued, and if you attempt to add new connections after the maximum number of connections is reached, they are rejected.
ACS Enhancements and Fixes SHOW CONNECTIONS FULL Command and Additional Screen Display Information After entering the SHOW CONNECTIONS FULL CLI command, connection details are now displayed at the bottom of the subsequent screen. Information displayed includes maximum allowable connections, number of used connections, number of free connections, and number of rejected connections.
ACS Enhancements and Fixes ACS Downgrade With this release, you can downgrade ACS from V8.8-1 to V8.7-1 or V8.6-1 (the base version). No other versions are supported. With this, changes have been made to associated screens. Refer to the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Maintenance and Service Guide for additional information. Note: If you are downgrading ACS V8.8-1 and pre-existing patches from V8.6 or V8.
ACS Enhancements and Fixes Note: Since other operating systems may not re-register their persistent reservation settings with the array controller based upon a single unit’s persistent reservation conflict, you must invoke the SET unit number FAKE_PR command if there are units with devices not mounted by Tru64 UNIX (that is, units mounted by another supported operating system).
ACS Enhancements and Fixes Table 3: New FMU Commands and Switches Item 1. FMU Command or Switch SHOW RESERVATIONS ALL SHOW RESERVATIONS unit Description Displays reservations that exist on one or more units. number 22 2. SHOW DEVICE_INFO unit SHOW DEVICE_INFO ALL Displays specific disk information, such as port number, target number, model ID, firmware version, model serial numbers, device flags, and metadata details. 3.
ACS Enhancements and Fixes ACS Fixes Table 4 summarizes fixes made to ACS with this release. Note: Fixes involving Last Failure Codes are very specific, and they address a specific cause for many controller issues; however, fixes for other conditions may exist for that same LFC code. Table 4: ACS fixes Item Subject Description 1.
ACS Enhancements and Fixes Table 4: ACS fixes (Continued) Item 24 Subject Description 2. New LFC OE199001 and updates to Repair Code 90 (continued) Occasionally, recursive controller inoperability problems propagated to the bottom controller during FRUTIL operations in HP StorageWorks Continuous Access. Follow these steps to troubleshoot the above Recursive Bugcheck error scenarios: 1. On “the other” controller, SET NOFAILOVER. 2.
ACS Enhancements and Fixes Table 4: ACS fixes (Continued) Item Subject Description 12. Controller inoperability and LFC 64030104 With this ACS version, there is no longer a conflict with the use of the previously unsupported SET HOST/SCSI OpenVMS command. Additionally, issues surrounding controller inoperability problems which resulted from two different entities executing send and receive diagnostic commands to the controller and resulting in LFC 64030104 has been resolved. 13.
ACS Enhancements and Fixes Table 4: ACS fixes (Continued) Item Subject Description 16. Adding unit above non-partitioned R5 set and receiving Error 1170: Partitions found on container, unit not created. This issue has been resolved for most cases. If there is an error noted when this is attempted, refer to the REINITIALIZE command in the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Command Line Interface Reference Guide for help. 17.
ACS Enhancements and Fixes Table 4: ACS fixes (Continued) Item 24. Subject Description Fibre Channel (FC) switch goes port INSYNC state to HSG Previous to this release, resource leaks occurred if a controller processed PLOGI frames against the rejected host list while the connection table was locked. The controller would report that all port conditions were Good. The FC switches would report as being in the INSYNC state for connection to one or more HSG controller ports.

Operating Constraints Operating Constraints This section describes the operating constraints for ACS V8.8-1. An operating constraint is a limitation placed on the operation of the controller. Other constraints on host adapters or other system components may also apply. Keep these constraints in mind to avoid problems and to help achieve the maximum performance from your controller. Refer to the documentation that came with your host server for more details.
Host Operating System Notes Host Operating System Notes The following section lists host-specific operating notes. Upgrading qla2x00 RPM to hp_qla2x00 RPM You must uninstall Secure Path before you upgrade from the qla2x00 binary RPM to the hp_qla2x00 scripted RPM. The qla2x00 will remove the qla2300 module from memory during an uninstall. Failure to remove Secure Path during an upgrade may result in a kernel panic. SWadmin Program If you are using SWCC, do not use option 21 in the SWadmin program.
ACS Anomalies ACS Anomalies If you issue the INITIALIZE SAVE_CONFIGURATION CLI command on a JBOD disk to save the controller configuration while the unit is not above the container, the command appears to work, but the save operation does not occur. You must place the unit above the JBOD, and then issue the INITIALIZE SAVE_CONFIGURATION to accomplish this task. 36 HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.
