Some issues can occur during different stages of the procedure.

Unexpected "storage failover show" command output

During the procedure, if the node that hosts all data aggregates panics or is rebooted accidentally, you might see unexpected output for the storage failover show command before and after the reboot, panic, or power cycle.

About this task

You might see unexpected output from the storage failover show command in Stage 2, Stage 3, Stage 4, or Stage 5.

The following example shows the expected output of the storage failover show command if there are no reboots or panics on the node that hosts all the data aggregates:

cluster::> storage failover show

                   Takeover
Node     Partner   Possible  State Description
-------  --------  --------- -----------------
node1    node2     false     Unknown
node2    node1     false     Node owns partner aggregates as part of the non-disruptive head upgrade procedure. Takeover is not possible: Storage failover is disabled.

The following example shows the output of the storage failover show command after a reboot or panic:

cluster::> storage failover show

                   Takeover
Node     Partner   Possible  State Description
-------  --------  --------- -----------------
node1    node2     -         Unknown
node2    node1    false      Waiting for node1, Partial giveback, Takeover is not possible: Storage failover is disabled

Although the output says that a node is in partial giveback and that storage failover is disabled, you can disregard this message.

Steps

No action is required; continue with the node-pair upgrade procedure.
