4.5
Remove RAID Array 410 Controller and Cache Modules
4.5.1 Unmount Filesystems that Reside on the RAID Array From the Host
Operating System.
Unmount from the host system any units that are accessed through a SWXRC-04
controller.
4.5.2 Using the SHUTDOWN Command and Turning Off Controller Power
CAUTION
If the correct steps for turning off power to an SWXRC-04 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 controller subsystem until all
shutdown procedures have successfully completed.
1. 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
In a Nonredundant controller configuration, you need only use the command:
swxrc>
shutdown this_controller
2. Turn off the power to the RAID subsystem only when the controller
shutdown
command has successfully completed, (ie. no response to keyboard).
4.5.3 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.
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. Pull the card
out and return it to Digital Equipment Corporation.
