Notes:
– You cannot set or reset the reserve attribute by using the PPRC
commands. To set or reset the reserve attribute, use the Storage
Navigator computer.
– The ShadowImage for z/OS suspend operations cannot be requested
using PPRC commands. The CSUSPEND/PPRCOPY SUSPEND commands
execute split operations on ShadowImage for z/OS pairs. Use the
Storage Navigator computer to suspend SIz pairs.
– If you issue the ESTPAIR or the SUSPEND command to a Pending
volume, the command will abnormally end by reporting CC = 12.
– CRECOVER command is not supported by ShadowImage for z/OS. When
you try to execute the CRECOVER command on the SIz S-VOL, the
command ends normally and the SIz pair will be deleted. If you execute
the command on the SIz T-VOL, the command will be rejected and end
abnormally by reporting CC = 8.
– CGROUP command is not used for ShadowImage for z/OS. For
information on the CGROUP command, see the TrueCopy for IBM z/OS
User’s Guide.
