Changing SCSI Version from SCSI-2 to SCSI-3 on HSG80 Controllers
SCSI-3 is the preferred protocol for DRM. If your operating system supports SCSI-3, HP
recommends that you change from SCSI-2 to SCSI-3. You can use either the static or rolling
upgrade procedure for this change.
Static Upgrade Procedure
This procedure requires that you stop all I/O and unmount all devices to the HSG80
controllers.
1. Verify that your host’s operating system supports SCSI-3. You can determine this by
referring to the DRM Release Notes.
2. Check for LUN 0 and unused devices on the SCSI-2 HSG80 controllers by issuing the
following CLI command:
SHOW UNITS
You will see a display similar to Example Display 1.
