Snapshot job fails and the snapshot command does not recognize the volume name

A snapshot job fails if the volume name exceeds 15 characters.

When you create and name a volume, a prefix or a suffix is added to the volume name. If the volume name contains more than 15 characters, addition of prefix or suffix may make the volume name exceed the limit of 27 characters. When you run the vxassist snapshot, command, it does not recognize the lengthy snapshot volume name and the snapshot job fails.

For example, if the primary volume name is PFItest123456789vol and the suffix 00043c8aaa is added to it, the volume name exceeds the limit. The command vxassist snapshot does not recognize the name PFItest123456789vol_00043c8aaa and the snapshot job fails.

Veritas recommended that you limit the primary volume names to up to 15 characters to create the VxVM mirror snapshots.
