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.
