Function
This is a TSO/E command called from REXX scripts.
This command acquires the FlashCopy information related to the specified volume from the storage
system, and stores the information into the FlashCopy information structure that was specified by
the STEM parameter.
If the specified volume is not found, or an I/O error occurred and the storage system information
cannot be acquired, this command creates an error message in the command return configuration
structure, and then returns a return code other than 0.
This command can be used for volumes of the following models on which FlashCopy Mirror Version
2 is installed:
HP XP12000/XP10000 Disk Array
HP XP24000/XP20000 Disk Array
HP P9500 Disk Array
