Unable to access storage |
If NetBackup cannot access the storage, one possible cause is that the storage server was created with the incorrect nbdevconfig storage type (-st) value. An AdvancedDisk storage server -st value is 5 (formatted disk, directly attached); values other than 5 are incorrect.
More procedural information is available about resolving this problem.
See Resolve an incorrect storage type problem. |
Multiple storage servers on Windows | AdvancedDisk does not support Common Internet File System (CIFS). If you try to configure multiple storage servers, NetBackup returns the following message: DSM does not support to use multiple Windows Storage Servers for
server type: AdvancedDisk.

Volume state changes to DOWN when volume is unmounted
|
If a volume becomes unmounted, NetBackup changes the volume state to DOWN. NetBackup jobs that require that volume fail.
To change the volume state to UP, mount the file system

Disk failure - AdvancedDisk
|
If recovery mechanisms do not protect a disk that fails, the backup images on that disk are lost. Operating system read and write errors may occur for the volume that represents the disk. NetBackup cannot use that volume because of the errors, and NetBackup jobs may fail.
To prevent NetBackup from trying to read from or write to the disk, you must change the volume state to DOWN in NetBackup. If the volume represents other disks that still function, those disks are not available because the volume state is DOWN. You may be able to read from the volume by mounting it manually. If so, you may be able to recover image fragments from any disks that did not fail.
If you replace a failed disk, you can use the same mount point for the replacement disk. Change the volume state to UP, and NetBackup uses that volume again.
Any valid backup images on that volume are available for restores.
