Example: ATQUERY Command
The meaning of each ATQUERY command example shown in the previous example is explained in the
following table.
The ATQUERY command must be issued to the T-VOL in the consistency group. If it is issued to any other

Using ShadowImage - FlashCopy
ShadowImage - FlashCopy is functionally compatible with the IBM FlashCopy host software function. PPRC
TSO commands and/or DFSMSdss commands may be used to perform ShadowImage - FlashCopy
operations on the XP128/XP1024/XP10000/XP12000. See ” Using ShadowImage - FlashCopy Host
Commands ” on page 87 for further information on using PPRC TSO commands and DFSMSdss
commands.
To enable the ShadowImage - FlashCopy function on the XP128/XP1024/XP10000/XP12000, SI390
and ShadowImage - FlashCopy must be installed and enabled on the disk array.
