Problem:
In the event of a failure, Protector attempts to revert the operations performed up to the point of the failure, but success cannot be guaranteed.
Solution:
If an Oracle online backup fails, then check that the operations described in the attachments to the log entry backupOnline Worksteps are reverted. It is especially important that the step endOnlineBackup is performed. If not then execute the steps described in the attachment to the log entry endOnlineBackup.
If an Oracle offline backup fails, check that the database is started.
If a mount fails then check if the status of the snapshot is mounted. If so, then perform an un-mount. In addition to this, check that an eventual ASM Diskgroup (asmcmd lsdg) is un-mounted and removed from the resource group (asmcmd umount ASM_DISKGROUP; srvctl remove diskgroup -g ASM_DISKGROUP). Do not try to issue a mount operation to another server, prior a successful un-mount operation.
