2. After you replace the part, you can return the failed part to NetApp, as described in the RMA
instructions shipped with the kit. Contact technical support at
NetApp Support, 888-463-8277 (North
America), 00-800-44-638277 (Europe), or +800-800-80-800 (Asia/Pacific) if you need the RMA number
or additional help with the replacement procedure.
Replace the real-time clock battery
You replace the real-time clock (RTC) battery in the controller module so that your
system’s services and applications that depend on accurate time synchronization
continue to function.
• You can use this procedure with all versions of ONTAP supported by your system
• All other components in the system must be functioning properly; if not, you must contact technical support.
Step 1: Shut down the impaired controller
To shut down the impaired node, you must determine the status of the node and, if
necessary, take over the node so that the healthy node continues to serve data from the
impaired node storage.
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;
see the
Administration overview with the CLI.
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 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.
