ACS Feature Support • Rolling upgrades must occur in succession. For example, you must upgrade from V8.6 to V8.7-1. • If you are performing a rolling upgrade, ensure that the variant for the existing ACS version being upgraded is the same as that of the next version to be upgraded. For example, if you want to upgrade ACS V8.6P-10, the ACS version to be upgraded must be the P variant of ACS V8.7-x. • You must use a dual-redundant configuration to perform rolling upgrades.
ACS Feature Support NOTE: Solely for the purpose of performing upgrades to ACS, the Solution Software Kit supports ACS V8.6. HP recommends that you avoid mixing ACS versions in the same Storage Area Network (SAN). The extended interoperability of the heterogeneous SAN allows you to mix several types of StorageWorks storage systems. HP recommends that you adhere to the following configuration rules when different storage products are shared in the same SAN: • HSG80 ACS Version 8.6 and EVA VCS Version 2.

ACS Feature Support NOTE: The cache flush timer value is displayed in the caching parameters section. This parameter is modified during the procedure and must be restored in step 20. 8. For each unit, identify and record the unit write-back cache, read-ahead cache, read cache, and Preferred Path characteristics by using the following command: HSGA> SHOW UNITS FULL These characteristics are modified during the upgrade procedure and must be restored in step 21.
ACS Feature Support NOTE: Repeat step 12 on both controllers (THIS_CONTROLLER and OTHER_CONTROLLER) until no unwritten data remains in either cache module memory. If unwritten data is present after several minutes, verify that the WRITEBACK_CACHE switch is disabled on all units by using the SHOW UNITS FULL command. For any units with the WRITEBACK_CACHE switch enabled, return to step 11 and proceed. 13.
ACS Feature Support The idle percentage for the HSG80 array controller is the first item displayed on the second line of the VTDPY display. If the HSG80 array controller is less than 50% idle and the screen display indicates activity, the processing load should be reduced. NOTE: You must wait a minimum of 60 seconds to allow for the failover and cache-flushing process to complete. The VTDPY display refreshes every 10 seconds. To exit VTDPY, press C, and then enter the following: HSGA> exit 16.

SWCC Agent Configuration Utility and the Displayed ACS Firmware Version After upgrading from ACS V8.6 (any variant or patch) to ACS V8.
ACS Feature Support To verify the correct version of ACS on the HSG80 array controller in this scenario, always use the SHOW THIS_CONTROLLER or SHOW OTHER_CONTROLLER CLI command from a CLI window or any CLI prompt. Disk Partitioning ACS allows partitioning of disk drives or storagesets for improved device management. A partition appears to the operating system as a single virtual disk. Up to eight partitions may be created per storageset or disk drive.
Configuration Rules • The initiator site data needs to be synchronized during a planned failover. Mini-merge—If the target becomes inaccessible, the writes that would have gone to the target are logged to the association set’s assigned log unit. An inaccessible target in this context refers to both links or target controllers shutting down. When the target becomes accessible, a full copy is not necessary. Only those host writes that occurred while the links were down are reissued.
SCSI-2 to SCSI-3 Migration — In SCSI-3 mode, the CCL is enabled, resulting in 127 visible LUNs and one CCL. • 1.024 TB storageset size • 96 host connections • 84 physical devices • 20 RAID 3/5 storagesets • 30 RAID 3/5 and RAID 1 storagesets (see Note) • 45 RAID 3/5, RAID 1, and RAID 0 storagesets (see Note) NOTE: For the previous two storageset configurations, this is a combined maximum, limited to no more than 20 RAID 3/5 storagesets.
Operating Constraints When migrating from SCSI-2 to SCSI-3, the controller checks for controller unit D0 and does not change modes until D0 (at all presented offsets) is deleted. One or more LUNs are lost after the mode change. If you are planning to move from SCSI-2 to SCSI-3, back up your data first. The data in LUN 0 (and any other offsets that map to LUN 0) that was used in SCSI-2 requires that the data be moved to a different LUN. It may be necessary to retrieve this data from a backup.
Operating Constraints SAN Boot Procedures Booting from the SAN is supported for Windows NT and Windows 2000. SAN boot procedures are available on the StorageWorks website. http://h18000.www1.hp.com/products/storageworks/san/documentation.html File System Limitations Table 9 describes known limitations that certain file systems have regarding storage unit size. Table 9: File System Storage Unit Limitations Disk Size Storageset Configuration Operating and File System 4 GB Any Windows NT4.
Saving Your Configuration If the other controller did not restart, follow these steps: 1. Press and hold the Reset button on the other controller. 2. Remove and re-insert the program card for the other controller. 3. Release the Reset button. NOTE: Whenever you are running FRUTIL you must quiesce all I/O. FRUTIL Limitation This limitation applies to users of ACS Version 8.7P with DRM only. FRUTIL cannot be run in remote copy set environments on the target side specifically when I/O is in progress.
Avoiding Problem Situations Avoiding Problem Situations Under certain conditions, you may experience unusual array controller behavior. This section presents information to help you avoid such situations and to recover from them if they occur. Adding, Moving, and Changing Devices The array controller maintains a configuration map of device types and locations. This map is used to communicate with devices.
Avoiding Problem Situations Replacing Array Controllers, Cache Modules, or External Cache Battery Storage Building Blocks You can replace the array controller, cache module, or external cache battery (ECB) storage building block (SBB) while the storage system is shut down. However, you must enter the SHUTDOWN THIS_CONTROLLER command prior to shutting down the storage system in order to make configuration changes.
Host Operating System Notes SWCC SCSI Connection The SWCC Client SCSI connection can sometimes produce the following error message when trying to connect through the CCL: Error scanning subsystem. Command Execution Error: [DeviceIOControl Error:] Additionally, physical devices may not appear in the Select Device drop-down list.
Host Operating System Notes Use the following procedure to upgrade your DS-KGPSA-BC HBA firmware from Version 2.x to Version 3.x: 1.
Host Operating System Notes 5. For all of the units with access enabled for offline connections, type: HSGA> SET DISABLE_ACCESS= HSGA> SET DISABLE_ACCESS= ... 6. Delete the offline host connections by typing: HSGA> DELETE HSGA> DELETE ... 7.
Host Operating System Notes • StorageWorks recommends that you load software directly from the Solution Software CD-ROM when installing drivers and running the Fibre Channel Setup utility. You may experience problems on some systems if you first copy the CD-ROM contents to a disk drive and then install from there. • Windows 2000 dynamic volumes are supported in transparent failover configurations or in Secure Path Version 4.0x multi-bus configurations. • Cloning a Windows 2000 dynamic disk is allowed.
Host Operating System Notes which you simply replace an FC HBA in one of your systems. During such a system or adapter changeover, be sure to manually remap drives to drive letters using Disk Manager. This restores proper access to your data. • If you replace an FC HBA in a server, you need to reinstall the HBA driver and then rerun the Fibre Channel Setup utility. This is so that Windows 2000 can automatically reload the original driver for this adapter and reset many of the important registry settings.
Host Operating System Notes For HBA driver versions above Version x-4.53a7, this value is set automatically by the Fibre Channel Software Setup included in this release of Solution Software. For HBA driver Version x-4.53a7, this parameter must be set manually. For all Windows configurations using this driver version, verify that the ResetTPRLO HBA driver parameter is set to 1 by using the LPUTILNT utility. Use the following procedure: 1. Choose Start and then Run. 2. Type LPUTILNT and select the first HBA.
Host Operating System Notes Large LUNs for Windows NT and Windows 2000 Enabling Large LUNs allows a Windows NT or Windows 2000 server to have access to LUNs beyond the 0-7 range, and to access more than 8 LUNs per target. The host can access unit D10 by leaving the connection offset at 0. The maximum number of LUNs supported is 256 per storage system. If using Secure Path Version 3.1A SP1, the maximum number of LUNs is 64 per storage system. If using Secure Path Version 4.
