If an attempt to configure the storage fails, the Configure Storage background task stops processing and lets you know that a failure has occurred. The background task also provides information on what failed and where the failure occurred. The steps of the Configure Storage background task show the point of failure, which would be the starting point for recovery efforts.
This cleanup must be performed because Configure Storage cannot back out of the operation when a failure occurs. The state is left as it was at the point of failure. PMAC provides XML files to facilitate removing any previous configurations of the Vdisks, Global Spares, and Host Volumes and to clear the Hosts and Controllers.
See Clearing or deleting the storage configuration for information on removing configuration data.
