CKM02281W VVDS VALIDATION FAILED. VOL=volser BLOCK=xxxx CODE(x) RBA=rba

Explanation
During BACKUP VVDS processing, the VVCR in the VVDS failed validation.

User response
The VVCR (created during initial allocation of the VVDS) has, since DFP
3.1, an EBCDIC eye-catcher "VVCR". This VVDS has at RBA zero (the VVCR location)
a record that does not have this eye-catcher. If this VVDS is an old version,
investigate the possible use of the PRE-DFP31 keyword in the BACKUP request.

Otherwise: Contact Technical Support. Have available the listing that contains
this message and the SCKMPARM member that controls execution.
