Replacing the MSA1000 Controller

If an MSA1000 Controller is failing, informational or error messages will be

displayed on the LCD panel of that controller, depending on the condition.

The following steps detail how to replace a failed MSA1000 Controller but can

also be used to re-seat the controller.

Note: Redundancy is supported during a hard drive expansion, migration, or

extension process and during regular drive rebuilds.

Note: Replacement MSA1000 Controllers include a new cache module. Remove this

new module from the replacement MSA1000 Controller and replace it with the cache

module from the failed controller. Using the same cache module will complete the disk

writes that may have been trapped in the controller’s cache. See “Replacing the

MSA1000 Controller Cache” for procedural instructions.

1. Press the controller’s thumb latch and pull the latch handle toward you 1.

2. Remove the MSA1000 Controller by pulling it straight out of the chassis 2,

as illustrated in Figure 12.
