ARCHC0115E

Explanation
 CHECK(IBMHSM,HSM_CDSB_VALID_BACKUPS) determined
that the number of valid CDS backup copies is below the owner- or
installation-specified critical level. A system with fewer CDS backups
than the critical level is considered to be at an increased risk of
discarding all valid CDS backup copies.
 Information messages
ARCHC0114I and ARCHC0106I are placed in the message buffer to describe
the check’s findings.

System action
 The system continues processing.

Operator response
 N/A

System programmer response
 Review the backup copy data sets
in message ARCHC0106I, which have a status of *** NOT FOUND ***,***
NOT VALID ***, or *** OBTAIN ERROR ***. Perform problem
diagnosis for these data sets.

Problem determination
 Investigate the reason for the backup
copy or copies in error. If applicable, SMF records can be analyzed
to determine how the data set was uncataloged or deleted.
 For *** NOT VALID *** data sets, DFSMShsm failed to create a
valid backup of the CDS. If a *** NOT VALID *** backup is followed
by one or more CATALOGED or FOUND backups,
it is possible the problem was transient. In all cases, investigate
the cause of the failure. The DFSMShsm joblog or the system log can be
used to determine if additional messages were issued during the failed
backup attempts.
For *** NOT FOUND *** data sets, the backup data set was
expected to be cataloged, however a catalog locate request for the
data set failed. Determine why the backup copy cannot be located.
If the control data sets are backed up to DASD, re-define the missing
backup data sets using the attributes of the existing backup data
sets for a given control data set.
For *** OBTAIN ERROR *** data sets, at OBTAIN request for
the data set on the cataloged volume failed. The catalog entry must
be scratched using an IDCAMS DELETE NOSCRATCH or similar utility.
If the control data sets are backed up to DASD, re-define the missing
backup data sets using the attributes of the existing backup data
sets for a given control data set.

 In some instances, a field titled "Temporary Critical Value"
may appear in the accompanying ARCHC0114I message. This field indicates
a temporary critical value was used for this execution of the check.
A temporary critical value is used when the latest version number
for the CDS backups is less than the owner- or installation-specified
critical value.
