If a switchback is taking a long time to finish, you can check on the status of in-progress baselines by using
the
metrocluster config-replication resync-status show command.
6. Reestablish any SnapMirror or SnapVault configurations.
Step 4: 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 A150
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.
•
If you have a SAN system, you must have checked event messages (
cluster kernel-service show)
for impaired controller SCSI blade. The
cluster kernel-service show command displays the node
name, quorum status of that node, availability status of that node, and operational status of that node.
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 Synchronize a node with the cluster.
Steps
1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message
