While copying Librarian Master File members from the Master File to a PDSE the volume on which the Master File resides is assigned to one LPAR while the other LPAR's in our system receive "START PENDING" messages for that volume until the job is complete. Both the Librarian Master and the target PDSE reside on the same Volume. Is there anyway to do this copy without exclusive use of the DASD Volume?
Yes
GRS settings we recommend you include a CONVERSION RNL for each master file, as follows:
RNLDEF RNL(CON) TYPE(GENERIC) QNAME(SYSDSN)
RNAME(master.file.dsn)
You can define multiple master files under one RNLDEF by specifying the high-level data set name qualifiers, as follows:
RNLDEF RNL(CON) TYPE(GENERIC) QNAME(SYSDSN)
RNAME(master.file.qualifier)
