Troubleshooting Backup and Restore Sessions
Chapter 12 583
The media in the library are not formatted and the media pool
with the media used for backup has a Strict policy
If your pool uses a Strict media allocation policy, unformatted media
are not used for backup. If no formatted media are available in the
library, Data Protector issues a mount request.
Action If you would like Data Protector to automatically format unformatted
media that are available in the library, set the media pool policy to
Loose . This can be modified in the media pool Properties .
The media in the library are formatted but are different from
those in the preallocation list
The media in the library are formatted but are different from those in
the preallocation list of the backup specification, and the media pool
specified has a
Strict policy.
If you are using a preallocation list of media in combination with the
Strict policy and the exact media specified in the preallocation list are
not available in the device when backup is started, a mount request is
issued.
Action The exact media specified in the preallocation list need to be available in
the device when the backup is started.
To use other media, if available in the device, in combination with the
preallocation list, modify the media pool allocation policy to
Loose .
To use any available media in the device without the preallocation list,
remove the preallocation list from the backup specification. Do this by
changing backup device options for the backup specification.
Unexpected Mounted Filesystems Detected
When restoring a disk image, you may get a message that the disk image
being restored is a mounted file system and will not be restored:
Object is a mounted filesystem => not restored.
This happens when an application on the disk image leaves some
patterns on the disk image. The patterns confuse the system call that
verifies whether the eventually mounted filesystem on the disk image is
mounted or not, so the system call reports that there is a mounted
filesystem on the disk image.
