Replace the caching module - FAS2600
You must replace the caching module in the controller module when your system
registers a single AutoSupport (ASUP) message that the module has gone offline; failure
to do so results in performance degradation.
• You must replace the failed component with a replacement FRU component you received from your
provider.

Step 1: Shut down the impaired controller
You can shut down or take over the impaired controller using different procedures,
depending on the storage system hardware configuration.
About this task
If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy
node shows false for eligibility and health, you must correct the issue before shutting down the impaired node.
ONTAP 9 System Administration Reference
You might want to erase the contents of your caching module before replacing it.
1. Although data on the caching module is encrypted, you might want to erase any data from the impaired
caching module and verify that the caching module has no data:
a.
Erase the data on the caching module:
system controller flash-cache secure-erase run
b.
Verify that the data has been erased from the caching module:
system controller flash-cache
secure-erase show -node node_name
The output should display the caching module status as erased.
2. If the impaired node is part of an HA pair, disable automatic giveback from the console of the healthy node:
storage failover modify -node local -auto-giveback false
3. Take the impaired node to the LOADER prompt:
If the impaired node is
displaying…
Then…
The LOADER prompt Go to the next step.
Waiting for giveback…
Press Ctrl-C, and then respond y when prompted.
