Issue
- MetroCluster IP nodes in one site shut down due to chassis over/under temperature
- Mediator assisted Automatic Unplanned SwitchOver (MAUSO) does not take place:
::> metrocluster operation show
Operation: switchover
State: failed
Start Time: mm/dd/yyyy
End Time: mm/dd/yyyy
Errors: Failed to validate the node and cluster components before the switchover operation.
Cluster1::node-01 (non-overridable veto): Automatic Unplanned Switchover could not be performed
as one of the prechecks failed. Run "event log show -message mcc.auso.trigFailed" to view the errors that occurred.
Verify Automatic Unplanned Switchover is enabled on both nodes by using the "metrocluster node show" command.
Use the "metrocluster switchover -forced-on-disaster true" command to switchover the DR-site storage manually.
