Stopping access to the controller
Single controller configurations
To service a failed or operational controller:
1.
Ensure that a known, good backup is available.
2.
Schedule a maintenance window.
3.
From the servers, stop all access to the MSA.
4.
Power off the MSA and disconnect the power cords to prevent any
new access.
Dual-controller configurations
If one of the two controllers has failed, you may remove the failed
controller for servicing at any time.
If both controllers are operational, but one or both of them need
servicing, you can schedule a maintenance window to perform the
service, or do the following to disable and service the standby
controller while operating in a non-redundant mode from the active
controller.
1.
Access the management utility for your MSA:
Table 2
Available management utilities
MSA model
Available management utilities
MSA1000
Command Line Interface
MSA1500 cs
Array Configuration Utility, Command Line Interface
MSA1510i
Storage Management Utility, Command Line Interface
IMPORTANT:
During this procedure, because you disable the
controller being removed, you temporarily operate in a non-redundant
mode.
2.
In your chosen management utility, disable the controller to be
removed. For details, see online help or your user documentation.
3.
Wait for the following LCD message to be displayed before
removing the controller:
204 ARRAY CONTROLLER DISABLED
IMPORTANT:
If an operational controller is removed from the
chassis without first being disabled, the active controller might halt. To
clear this fault condition, power cycle the MSA.
Replacing the controller/components
Step 1: Remove the controller
1.
Press the controller thumb latch and rotate the latch handle out (1).
2.
Pull the controller straight out of the chassis (2).
2
Step 2: Remove the cache module
(if applicable)
NOTE:
If you are not replacing controller cache modules,
proceed to Step 3.
IMPORTANT:
Replacement controllers include a new cache
module. Remove this new module from the replacement controller and
replace it with the cache module from the failed controller. Using the
same cache module completes disk writes trapped in the cache.
IMPORTANT:
When replacing a controller cache module in a
dual-controller configuration, the memory size of the new module must
be identical to that of the already installed module.
NOTE:
The controller in the following illustration has been rotated
to show the side and rear of the controller.
