6.9 Moving Write-Back Cache Modules
When moving a write-back cache module to a new environment (that is,
different controller, different devices), it is very important that you perform a
clean shut down of the controller and clear any data from the cache. Follow
these steps to move a write-back cache module:
1.
Shut down the controller and flush unwritten data from the cache module
using the appropriate CLI command:
SHUTDOWN THIS_CONTROLLER
or
SHUTDOWN OTHER_CONTROLLER
2.
Wait for the SHUTDOWN command to complete and verify that the
controller does not report any errors.
3.
Remove the controller and cache module following the instructions in the
HSZ40 Array Controller HSOF Version 3.1 Service Manual.
The
SHUTDOWN command flushes cache data to the devices, and
you can install the module in another location without problems
caused by uncleared cache data.
