Solution Problem
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
Volume state changes to
DOWN when volume is
unmounted
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.
