Storage failover is disabled after a panic
Applies to
ONTAP 9
Answer
- If a node panics within 60 seconds of taking over the partner node, storage failover is disabled.
- You may see a message in EMS like the following:
Sun Aug 14 19:06:23 +0000 [CLUSTER-NODE-02: config_thread: cf.fm.panicToInProgress:alert]: Failover monitor: Panic during takeover; takeover will be disabled on reboot.
- It needs to be re-enabled manually after the panic issue is fixed.
Additional Information
As the node panic'ed so soon after a takeover, ONTAP will try to protect the system from repeated occurrences where both nodes in an HA pair becomes unavailable.
