What creates the condition during a Backup to get the following messages and no Backup done by Ca Disk?
ADSDF102 4106 ADR730W (001)-DTDSC(01), CLUSTER TMNTDDA.MVSNORZZ.Z11.THFT IS OPEN
ADSDF102 4106 ADR722E (001)-DTDSC(02), DATA SET TMNTDDA.MVSNORZZ.V1F.AMF IN CATALOG CATALOG.TEST05 ON VOLUME NVB7II IS UNAVAILABLE AND CANNOT BE
ADSDF102 4106 PROCESSED - BACKUP-WHILE-OPEN STATUS IS 110
ADSDF102 4106 ADR415W (001)-DTDSC(04), NO DATA SETS WERE COPIED, DUMPED, OR RESTORED FROM ANY VOLUME
Release: SMDI3900200-12.5-Disk-Backup and Restore-for z/OS
The answer can be found into IBM book: https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R3SC236868/$file/adru000_v2r3.pdf The error 110 means:
The data set was updated and a split or extend is completed, which invalidates any dump that was in progress.
When concurrent copy is used, the chances of an in-progress-dump being invalidated by a split or extend is significantly reduced.
Here is the information regarding this problem provided by IBM into the same book.
Bypassing backup-while-open processing (OY63531) When DFSMSdss encounters a data set marked as backup-while-open (BWO) eligible, DFSMSdss processes it accordingly.
If the BWO indication is on erroneously, the BWO processing may be bypassed for a logical data set dump. This function is affected by setting the flag at offset X'15' in ADRPATCH.
The settings are listed below:
X'00' BWO processing is performed. Any setting other than X'00' BWO processing is bypassed.
