HSG80 Array Controller V8.7 Maintenance and Service Guide
Upgrading the Subsystem
The controller’s percent idle is the first item displayed on the second line of the
VTDPY display. If the controller is less than 50% idle, the processing load should
be reduced.
NOTE: The VTDPY display refreshes every ten seconds.
To exit VTDPY, enter the following:
HSGA> <cntl>C exit
Repeat this step on the other controller.
3. 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.
b.
If the controller is in SCSI-2 mode and the CCL is enabled, record the status
for restoration in step 19.
c.
Disable the CCL using the following command:
HSGA> SET THIS_CONTROLLER NOCOMMAND_CONSOLE_LUN
