Version 2 IBM FlashCopy Compared Item
• When you specify the source volume
for a volume relationship as the copy
target, the entire volume relationship
will be withdrawn.
• When you specify the target volume
for a volume relationship as the copy
target, the volume relationship will
be withdrawn.
CAUTION: When only a part of the
relationship that is the copy target is
included in the specified extent as the
copy target, the volume relationship will
not be withdrawn.
Comparison of Supporting Commands
IBM FlashCopy supports the ICKDSF commands, while Version partly supports. However, if you
execute the commands to a TrueCopy for Mainframe M-VOL or ShadowImage for Mainframe
S-VOL that is in pending status, the commands will end abnormally with CC=12. See
“If an ICKDSF
Command Ended Abnormally” (page 154) for details on how to avoid the abnormal ending. In
addition, Version 2 does not support the following parameters of the TSO commands.
