3 Performing Compatible FlashCopy operations
This chapter describes how to operate Compatible FlashCopy.
Commands for Compatible FlashCopy operations
Compatible FlashCopy supports PPRC TSO commands, DFSMSdss commands, ICKDSF commands,
ANTRQST Macro commands, and z/VM CP commands to enable you to perform Compatible
FlashCopy operations from the zSeries and S/390 host system. The operating system versions that
support Compatible FlashCopy are OS/390 V2R10, IBM V1R0 and z/VM V5R3 and higher. In
addition, Compatible FlashCopy runs on the operating system z/VM V5R3 and higher. An
appropriate PTF is necessary for each.
This user’s guide provides only the instructions for using commands that are necessary to perform
Compatible FlashCopy operations. For detailed information on using the PPRC TSO commands,
DFSMSdss commands, ICKDSF commands, ANTRQST Macro commands, and z/VM CP
commands, see the IBM user documents.
• To use the PPRC TSO commands, you must add the command names to the AUTHCMD PARM
of IKJTSOxx, which is a member of SYS1.PARMLIB. (This is because the host system is protected
by RACF Facility.)
• Compatible FlashCopy supports VSAM datasets. However, when the user specifies attributes
for the copy source extents that differ from those specified for the copy target extents, DFSMSdss
invokes a different program (such as IDCAMS), and as a result, Compatible FlashCopy may
not be able to use VSAM datasets.
The following commands are the PPRC TSO commands, DFSMSdss commands, ICKDSF
commands, ANTRQST Macro commands, and z/VM CP commands that are available for
Compatible FlashCopy.
