Upgrading the Subsystem
182 HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software
Maintenance and Service Guide
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. Connect a PC or terminal to the maintenance port of controller A.
3. If the controller is running in SCSI-2 mode and the CCL is enabled, you must
disable the CCL prior to upgrading by performing the follow substeps:
a. Determine if the controller is in SCSI-2 mode and the CCL is enabled by
entering the following command:
HSGA> SHOW THIS_CONTROLLER
Figure 76 shows only a portion of the resulting display—arrows point to
the pertinent status indication.
Figure 76: Screen display indicating SCSI version and CCL setting
b. If the controller is in SCSI-2 mode and the CCL is enabled, record the
status for restoration in step 14 on page 185.
c. Disable the CCL by entering the following command:
HSGA> SET THIS_CONTROLLER NOCOMMAND_CONSOLE_LUN
