Error Management
Actions When Error Occurs
This chapter explains how to address errors that occur during backup when VSS Provider is
used.
When Backup has Errors
W
hen an error has occurred during backup, investigate the cause of the error using the
procedure below and re-execute the backup after eliminating the cause of the error.
1.
Verify if the error was output in the application’s event log.
2.
If you were able to confirm the error number and error message, check Appendix A
“Error Messages at Time of Failure”.
3.
Refer to the explanation in (Measure) and eliminate the cause of the error.
If there are unformatted partitions, a warning may be output to the (application) event log
when executing VSS backup. This does not affect backup processing. For details, refer to
“Event Log Warning Message.
When VSS must be Restarted
When the VSS must be restarted, follow the instructions:
1.
From the Windows (Start) button, select (Administrative Tools) > (Services).
2.
Select (VSS Provider) and restart it.
3.
Confirm that the service was started.
When Returning Volume to Initial State
Sometimes, an LV or RV for performing VSS backup enters a state in which backup is not
possible because of an error during backup. To initialize the state of the LV or RV to a state
in which re-execution is possible, different operations are needed for operation in which the
snapshot function is used and operation in which the data replication function is used.
Execute the operations for LV or RV for which backup failed.
If Protection Manager is selected as a requester, troubleshoot by referring to the “CLI
Command Reference Guide”.
Backup Server Connected to Snapshot LV
This section describes the procedure that returns a volume to its initial state when an error
occurred during operation using the snapshot function. Execute the procedure below for all
volumes subject to backup.
1.
Start a command prompt on the backup server.
