Step 5: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return
& Replacements page for further information.
Replace a DIMM - AFF A220 and FAS2700
You must replace a DIMM in the controller module when your system registers an
increasing number of correctable error correction codes (ECC); failure to do so causes a
system panic.
All other components in the system must be functioning properly; if not, you must contact technical support.
You must replace the failed component with a replacement FRU component you received from your provider.
Step 1: Shut down the impaired controller
To shut down the impaired controller, you must determine the status of the controller and,
if necessary, take over the controller so that the healthy controller continues to serve data
from the impaired controller storage.
About this task
• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
“Returning SEDs to unprotected mode” section of the ONTAP 9 NetApp Encryption Power Guide .
ONTAP 9 NetApp Encryption Power Guide
• If you have a SAN system, you must have checked event messages (
event log show
) for impaired
controller SCSI blade.
Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be
resolved before you proceed with the replacement.
• 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 controller shows false for eligibility and health, you must correct the issue before shutting down the
impaired controller; see the
Administration overview with the CLI .
• If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration
State is configured and that the nodes are in an enabled and normal state ( metrocluster node show ).
Steps
1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message
MAINT=number_of_hours_downh
The following AutoSupport message suppresses automatic case creation for two hours:
cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h
2. Disable automatic giveback from the console of the healthy controller:
storage failover modify
–node local -auto-giveback false
3. Take the impaired controller to the LOADER prompt:
