Remove RAID Array 410 Controller and Cache Modules
3.5.1 Use the SHUTDOWN Command to Turn Off Controller Power
To turn off the power to your RAID subsystem make sure you turn off the power
properly by using the following steps:
CAUTION
If the correct steps for turning off the power to an
SWXRC-04 controller are not followed, there is a
potential for loss of data that may exist on any
devices connected to the array.
CAUTION
Do not turn off the power to the RAID subsystem
until all shutdown procedures have successfully
completed.
1. Invoke
the
shutdown
command from the maintenance terminal.
2. For dual-redundant configurations, shutdown each controller, one at a time. From the
maintenance terminal connected to the maintenance port of one controller, use both
of the following commands:
swxrc> shutdown other_controller
swxrc> shutdown this_controller
3. In a single controller configuration, you need only use the command:
swxrc> shutdown this_controller
4. Turn off the power to the RAID subsystem only when the controller
shutdown
command has successfully completed.
3.5.2 Controller Module Removal
Use the following procedure to remove the controller module. Repeat the procedure for
dual-redundant controller configurations.
1. Access the controller modules in the cabinet.
CAUTION
Never remove a controller while it is still servicing
devices. Doing so may destroy data.
2. Unsnap and remove the ESD shield covering the program card by pulling out on the
two retainer buttons.
3. Remove the program card by pushing the eject button on the controller panel. Pull
the card out and return it according to the instructions provided.
