ACS Feature Support ACS Feature Support The following sections provide details for specific ACS features. SCSI-2 to SCSI-3 Migration In order to extend interoperability within the heterogeneous SAN, HP highly recommends that customers begin migrating from SCSI-2 to SCSI-3 protocols. Moving to SCSI-3 allows greater diversity in the operating systems (OS) and storage products (including EVA) that comprise a SAN. All migrations from SCSI-2 to SCSI-3 should be planned during scheduled downtime.
Host Operating System Notes Host Operating System Notes The following section lists host-specific operating notes. Host Operating System Support of Multi-Bus Failover Tru64 UNIX V5.1x has multi-bus failover support built into the operating system, which takes advantage of the array controller’s ability to support multi-bus failover. Tru64 UNIX V4.0x does not support multi-bus failover. Booting Tru64 UNIX from the Array Tru64 UNIX Versions 5.1A and 5.
Host Operating System Notes Note: Boot support for Fibre Channel disk devices on nonclustered Tru64 UNIX systems is fully supported with Alpha SRM console firmware V5.6. HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.
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. 38 HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.
