Attempt a recover procedure only after a complete and thorough
investigation of the cause of the system failure. Attempt to resolve
those issues by using other service procedures.
Attention: If you experience
failures at any time while running the recover system procedure, call
the IBM Support Center. Do not attempt to do further recovery
actions, because these actions might prevent support from restoring
the system to an operational status.
Certain conditions must
be met before you run the recovery procedure. Use the following items
to help you determine when to run the recovery procedure:
- Check that no node in the system is active and that the management
IP is not accessible. If any node has active status, it is not necessary
to recover the system.
- Resolve all hardware errors in nodes so that
only node errors 578 or 550 are present. If
this is not the case, go to Fix hardware errors.
- Ensure all backend storage that is administered by the system
is present before you run the recover system procedure.
- If any nodes have been replaced, ensure that the WWNN of the replacement
node matches that of the replaced node, and that no prior system data
remains on this node.
