Explanation: Insufficient disk space is available to run this job.
Recommended Action: Try the following possible solutions:
If there are images on disk that can be expired, expire them, and run nbdelete to delete the images from disk.
It may be that NetBackup is creating disk images more quickly than they are expiring. If so, modifications to policies may be necessary to change the rate of image creation/expiration for the disk.
It may be helpful to lower the high water mark and/or low water mark for the disk group.
