You are 100% correct. What a PITA! This is going to cause a MAJOR disruption to the way that we back up for DR. ref: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2U261/6.3. 1.2 <quote> Physical dump does not provide the quiesce serialization mechanism, and it is not recommended for backing up mounted HFS data sets. If you do perform a physical dump of an HFS, do not specify the SHARE keyword. The SHARE keyword applies to the SYSDSN ENQ, and therefore does not provide protection against updates during dump. Attention: Exercise caution if you use TOL(ENQF) during a physical dump of HFS data sets. Unlike other types of data sets, if an HFS is updated during a physical dump with TOL(ENQF), a subsequent restore will likely result in an unusable data set. </quote> and http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/DGT2U261/6.3. 2.2 <quote> Physical dump does not provide the quiesce serialization mechanism, and it is not recommended for backing up mounted zFS data sets.
