Shutdown Upgrade Procedure - HP StorageWorks HSG80 Array Controller V8.7 Maintenance And Service Manual

Shutdown Upgrade Procedure

This upgrade procedure applies to dual-redundant controller configurations and all
single-controller configurations. Specific controllers are referred to as Controller A or
Controller B during the procedure. For clarity, the CLI prompts illustrated in this
procedure use HSGA> and HSGB> to indicate which controller (A or B) is used.
IMPORTANT: The following steps must be followed carefully for the upgrade procedure to work
properly.
The procedure takes approximately five minutes.
NOTE: This procedure is written for dual-redundant controller configurations. If upgrading a
single-controller configuration, disregard references to multiple controllers and Controller B.
1. From a host console, stop all host activity to the controllers and dismount the
logical units in the subsystem.
2. If the controller is running in SCSI-2 mode and the Command Console LUN
(CCL) is enabled, you must disable the CCL prior to upgrading.
a. Determine if the controller is in SCSI-2 mode and the CCL is enabled using
the following command:
HSGA> SHOW THIS_CONTROLLER
The following text is only a portion of the resulting display—arrows point to the
pertinent status indication.

Time: 14-MAR-2001
Command Console LUN is lun 0 (IDENTIFIER = 0)
b. If the controller is in SCSI-2 mode and the CCL is enabled, record the status
for restoration in step 12.
