HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Maintenance and Service Guide (EK-G80MS-SA. C01, March 2005)

Upgrading the Subsystem

Maintenance and Service Guide
Caution: Stop at this point when upgrading the initiator site controllers and
proceed to upgrade the target site controllers.
Failure to stop at this point, without fully upgrading the target site controllers,
can cause the initiator and target site controllers to become dysfunctional and
prevent the host from accessing data storage in these subsystems.
Part 3: Target site upgrade
Continue the rolling upgrade by entering the following procedure on the target site
controllers:
Caution: Before attempting the upgrade, verify that the subsystem is in a
stable state. This can be verified by examining the controller Reset button and
the adjacent LEDs. The Reset button should be flashing, while all LEDs should
be off (no light). Failure to perform this verification can result in the loss of
data or leave the controller in an unusable state.
Note: If you have several servers with multiple LUNs in your storage area network
(SAN) and are using HP StorageWorks Secure Path Manager, HP recommends that
you verify that all units are online by using the SHOW UNITS FULL CLI command.
Afterwards, move all LUNs to the controller to be updated last by using
HP StorageWorks Secure Path Manager. (LUNs may be moved by either controller.)
Note: During the target site upgrade, one of the initiator site controllers can restart
with an instance code of 0xE096980. This potential restart is expected and the
associated instance code can be disregarded.
1. Connect a PC or terminal to the maintenance port of controller A, at the target
site.
2. Determine if the controller is in SCSI-2 mode and the CCL is enabled by
entering the following command:
