Shutdown upgrade procedures for DRM 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.
Note: The following steps must be followed carefully for the upgrade to work
properly. This procedure takes approximately 5 to 10 minutes. The units involved are
unavailable during the upgrade procedure.
Caution: Before upgrading, 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 buttons should be flashing. All adjacent LEDs should be off
(no light). Also, verify that the controller is not reporting a lot of event
information. Issue a SHOW THIS CONTROLLER CLI command from each
involved controllers to ensure controllers are responding to CLI commands as
well. Failure to perform this verification can result in data loss or leave the
controller in an unusable state.
Note: HP recommends that no remote copy set normalize, merge, or copy operations
be active at the time the upgrade begins.
The shutdown upgrade consists of three parts:
■ Part 1: Initiator site controller (initial steps), page 203
■ Part 2: Target site upgrade, page 207
■ Part 3: Initiator site upgrade (final steps), page 211
Part 1: Initiator site controller (initial steps)
Begin the shutdown upgrade by entering the following procedure on the initiator
site controllers:
1. From a host console, stop all host activity to the controllers, and then
dismount the logical units in the subsystem.
2. Connect a PC or terminal to the maintenance port of controller A, at the
initiator site.
