Latest patches and updates
For other Veritas products such as the Veritas File System and Volume Manager, or Storage Foundation, install the latest patches and updates for those products. Installing the latest software can fix a variety of issues.
For example:
If you receive status code 156 on a FlashSnap alternate client backup, and the client data is configured in Storage Foundations for Windows 4.1, note: the volume to be backed up may not appear on the alternate client. This situation can occur even though the disk group has been split on the primary client and the disk was deported to the alternate client. Installing the latest Storage Foundation patches has been known to correct this problem.
