8.3 Adding, Moving, and Changing Controllers, Cache Modules, or
External Cache Batteries
It is permissible to replace the controller, cache module, or external cache battery
while the subsystem is shut down. However, you must enter the SHUTDOWN
THIS_CONTROLLER command before shutting the subsystem down to make
configuration changes. If two controllers are configured in a dual-redundant
configuration, you must first enter the SHUTDOWN OTHER_CONTROLLER
command.
These commands instruct the controllers to flush all unwritten data from the
cache modules and discontinue all I/O activity. For more information regarding
the SET controller command or maintenance and replacement of the controller,
cache module, and external cache battery, see the HSG80 Array Controller ACS
Version 8.5 Configuration Guide and the HSG80 Array Controller ACS Version
8.5CLI Reference Guide.
8.4 Establishing a SWCC Direct Connection
If the first attempt to establish a SWCC SCSI or serial direct connection fails, try
making the connection again.
