If S-VOL and T-VOL of Compatible FlashCopy are both Thin Provisioning Z volumes, the number
of pages remaining in T-VOL may differ depending on the timing.
The procedures when you use a DFSMS,TSO, or ICKDSF command are as follows. You cannot
perform Fast Reverse Restore when you use DFSMSdss.
Using DFSMS commands to share Compatible FlashCopy and Cnt Ac-S Z volumes
Note: If the status of the Cnt Ac-S Z pair is duplex, you need to use a TSO command instead of a
DFSMS command.
To share a Compatible FlashCopy S-VOL and a Cnt Ac-S Z R-VOL:
1. To maintain the consistency of data, terminate I/O operations to the volumes of Cnt Ac-S Z
pairs.
2. Suspend the Cnt Ac-S Z pair. Example:
CSUSPEND DEVN(X'dev#) PRIM(X'ssid') serial# X'cca' X'lss')
SEC(X'ssid' serial# X'lss')
