If... Then...
All nodes show true for both health and
eligibility. Proceed to Step 3.
The impaired node shows false for health. Proceed to the next step.
Any nodes show false for eligibility. Resolve any cluster issues as needed before
continuing with this procedure.
Any nodes other than the impaired node
show false for health. Correct the problems that cause the health
issues on the nodes before continuing with
this procedure.
2. Either shut down or perform a takeover of the impaired node, depending on
your configuration:
If the impaired node is in... Then...

1. Check the status of the impaired node by
entering the following command from
the healthy node's console:
storage failover show
2. Take one of the following actions,
depending on the result of the
storage
failover show
command:
v
If the impaired node is not running or
has been taken over by the healthy
node, go to step 4.
v
If the impaired node took over the
healthy node, give back the healthy
node using the
storage failover
giveback command from the impaired
node, go to the next step.
v
If the impaired node has not been
taken over by the healthy node and is
running, go to the next step.
3. Take over the impaired node by entering the following command:
storage failover takeover -ofnode impaired_node_name
When it is taken over, the impaired node automatically reboots and displays
the
Waiting for giveback...
message.
4. Wait at least two minutes after takeover of the impaired node to ensure that the
takeover completed successfully.
5. With the impaired node showing the
Waiting for giveback...
message, shut it
down. The method you use to shut down the node depends on whether remote
management via a Remote LAN Module (RLM) is used and whether or not the
system is in a dual-chassis or single-chassis configuration.
