5.8.1.2 Replacing a Controller
There are three possibilities that occur regarding the saving of a subsystem
configuration when replacing a controller:
• Controller is “factory initialized” and no prior subsystem configuration
data
• Controller is not “factory initialized’ and has no prior subsystem
configuration data
• Controller has some prior subsystem configuration data in it
With any of these possibilities, a local connection should be made to the
controller and a printed copy of the configuration as shown by the CLI
command: SHOW disk should be available before replacing the controller.
5.8.1.2.1
Controller Factory Initialized (No Configuration Data)
With this situation, the new controller searches the devices in the subsystem
for a saved configuration:
• Upon finding a saved configuration, it loads it into the new controller’s
NVMEM and brings the subsystem on-line (it is not necessary to issue an
INITIALIZE command after installing a new controller).
If a local connection was made to the maintenance port of the
controller, then the CLI will display the events going on:
“Looking for Configuration,” “Restarting Configuration,” etc.
• If a saved configuration is not found, no configuration data is loaded into
NVMEM and the subsystem is not brought on-line. Subsystem
configuration data will have to be entered into the controller. The methods
of entering this data is by way of the StorageWorks Command Console
(SWCC) or by way of the CLI command: RUN config through a
maintenance terminal (RUN config brings up the configuration utility)
Refer to the HSZ50 Array Controller HSOF 5.1 Configuration Manual,
Chapter 4 for additional details.
If a local connection was made to the maintenance port of the
controller, then the CLI will display the events going on:
“Looking for Configuration,” “No Configuration Found” etc.
