Hi John! We thought that the default tape BLKSIZE has been changed to 65k
from 32k in zOS 1.4. Our DR site which has an older zOS can not read the 65k
BLKSIZE tapes. We want to write the tapes at 32K.
My latest research into the problem shows that APAR OA13742 changed the
way the output tape is written and puts the actual Blocksize in the tape label.
It used to be 0.
My issue is that the exit (ADRUIXIT) would work for JCL driven ADRDSSU
invocations but not from HSM invocations.
Errol,
Smaller BLOCKSIZE means worse performance. ADRDSSU has been using 64k blocksize for years. The change was only in labels and RMM or other TMS recording.
