ARC0704E

Explanation
 While performing a backup, dump, or recover operation
on a volume with volume serial number volser1, DFSMShsm attempted
to perform the identified operation on a copy of the VTOC of the volume
being processed. This copy of the VTOC resides on a backup or migration
level 1 volume for backups or recovers, or on a migration level 1
volume for dump. The copy would be used to control a volume recovery
or restore if necessary. In an attempt to perform the suggested operation
on the VTOC copy data set, an error occurred.
 If the error
was ALLOCATING VTOC COPY DATA SET the volume serial number where the
allocation of the VTOC copy data set failed is identified by volser2.
 If FAST REPLICATION DUMP processing was interrupted previously
for this volume, the VTOC copy might have been partially allocated.
 Note: If SMS is attempting to manage the allocation of the
HSM.VTOC.* data set, check ACS routines to be sure that the HSM.VTOC.*
data sets are not SMS managed.

System action
 The volume operation ends. DFSMShsm processing continues.

Programmer response
 If FAST REPLICATION DUMP processing
was interrupted previously for this volume and now fails because it
cannot allocate the VTOC copy data set, the existing VTOC will need
to be deleted prior to the retry of the DUMP function. Volser2 is
the name of the volser where the VTOC resides.
The specific VTOC copy data set can be identified by 'DFHSM.DUMPVTOC.timestamp.Vvolser1.Ddate'.
Issue a LIST COPYPOOL(cpname) for copy pool version
date and time stamps.
