B.6 Troubleshooting
3PAR Recovery Manager 4.1.0 For Microsoft Exchange 2010 User’s Guide
Problem:
Recovery Manger shows the "Error - VSS Asynchronous operation failed. It is recommended
that you wait 10 minutes and then try the operation again" message when the create
command is executed.
Suggestion:
When you encounter this error message, run the vssadmin list writers command to list
all of the available writers on the system that are taking the snapshot of the Exchange Mailbox
Database. Make sure the Microsoft Exchange Writer status is stable. If the status is other than
stable, you need to restart the Exchange server service to reset the writer status.
Problem:
Recovery Manager shows the "ERROR: Failed - Virtual Copy creation failed for Mailbox
Database" message after an unexpected termination of the virtual copy create process.
Suggestion:
When Recovery Manager unexpectedly terminates, an internal locking file might still exist on
your Exchange server system. You need to remove the locking file manually for the create
process to run through. The locking file can be located under:
<InstallationPath>\Exchange\vclock. Use the rmexch reset command to reset the lock.
Problem:
The event viewer shows the “Volume Shadow Copy Service error: Unexpected error
IOCTL_STORAGE_QUERY_PROPERTY(\\.\PHYSICALDRIVE2, StorageDeviceProperty) -
BuildLunInfoForDrive. hr = 0x80070002." error when a Virtual Copy creation is in progress.
Suggestion:
When this message is logged by the Volume Shadow Copy service, it notifies the user that the
initial search on the imported volume is not complete. It will try again to make sure the
snapshot can be imported successfully. If the snapshot process still fails and this error is logged,
please contact 3PAR.
