Veritas NetBackup™ Snapshot Client Administrator's Guide

Storage lifecycle polices and Snapshot Client troubleshooting

The section includes information about various error messages related to SLPs and snapshots.

If you configure a snapshot method for a policy, and the schedule specifies a lifecycle policy, the life cycle policy must include a snapshot destination. Otherwise, an error such as the following appears in the NetBackup Problems report:

   snapshot backup: tashina11_1204305543 cannot be used with a 
    lifecycle policy NoSnapshot that does not include a snapshot 
    destination.

Error 156 can be a result of different problems, listed below are some of them:

VxVM failing to get the version of the disk group, run appropriate VxVM command outside of NetBackup to see whether you can get the version information for the disk group in use.
