About this task
Attention: This service action has serious implications if not completed properly.
If at any time an error is encountered not covered by this procedure, stop and call
the support center.
Run the recovery from any node canisters in the system; the node canisters must
not have participated in any other system.
Note: Each individual stage of the recovery procedure can take significant time to
complete, depending on the specific configuration.
Procedure
1. Point your browser to the service IP address of one of the node canisters.
If the IP address is unknown or is not configured, assign an IP address using
the initialization tool; see "Procedure: Changing the service IP address of a
node canister" on page 271.
2. Log on to the service assistant.
3. Check that all node canisters that were members of the system are online and
have candidate status.
If any nodes display error code 550 or 578, remove their system data to place
them into candidate status; see "Procedure: Removing system data from a node
canister" on page 270.
4. Select Recover System from the navigation.
5. Follow the online instructions to complete the recovery procedure.

hour, and mm is the minute.
Attention: If the time stamp is not less than 24 hours before the failure,
call the support center.
