Hi all.
We ran out of scratch tapes on one of the systems I look after. After
investigation, it appears that DFRMM (or DFHSM) doesn't seem to be releasing
old CDS backup tapes back to the scratch pool.
I have the following coded in ARCCMDxx for DFHSM CDS backups: -
SETSYS CDSVERSIONBACKUP(BACKUPCOPIES(4))
SETSYS CDSVERSIONBACKUP(BACKUPDEVICECATEGORY(DASD))
SETSYS CDSVERSIONBACKUP(DATAMOVER(DSS))
SETSYS CDSVERSIONBACKUP( -
BACKUPCOPIES(4) -
BACKUPDEVICECATEGORY(TAPE(NOPARALLEL -
RETPD(0) UNITNAME(V3480)))-
DATAMOVER(HSM) -
)
When I issue a QUERY CDSVERSIONBACKUP, I get: -
ARC0101I QUERY CDSVERSIONBACKUP COMMAND STARTING ON 610
ARC0101I (CONT.) HOST=3
ARC0375I CDSVERSIONBACKUP, 611
ARC0375I (CONT.) MCDSBACKUPDSN=HSM.MCDS.BACKUP,
ARC0375I (CONT.) BCDSBACKUPDSN=HSM.BCDS.BACKUP,
ARC0375I (CONT.) OCDSBACKUPDSN=HSM.OCDS.BACKUP,
ARC0375I (CONT.) JRNLBACKUPDSN=HSM.JRNL.BACKUP
ARC0376I BACKUPCOPIES=0004, BACKUPDEVICECATEGORY=TAPE 612
ARC0376I (CONT.) UNITNAME=V3480, DENSITY=*, RETPD=0000, NOPARALLEL,
ARC0376I (CONT.) LATESTFINALQUALIFIER=V0006021, DATAMOVER=HSM
ARC0101I QUERY CDSVERSIONBACKUP COMMAND COMPLETED ON 613
ARC0101I (CONT.) HOST=3
So we're backing up DFHSM CDS's to (virtual) tape, and keeping four old
versions. Froopy.
In RMM, I found MANY old versions of the CDS files on tape - going back to
2015. For instance: -
'HSM.MCDS.BACKUP.V0005355' with an expiration date of 2015/138.
RMM has these volumes as a status of MASTER, so RMM thinks it contains valid
user data, which it really doesn't...
How do I get these tapes (preferably automatically) returned to the scratch
pool?
