Running the ICKDSF program

Table 1 contains information about running the ICKDSF REFORMAT REFVTOC program. Note that this function should be run from a system in the production SMSPlex to ensure that DFSMS space statistics are correctly updated and accurately reflect the space on the primary and/or secondary volumes.

Table 1. Determining when to run the ICKDSF REFORMAT REFVTOC program
If . . .	Then . . .	Comments . . .
An XRC volume pair is established or reestablished using the NOCOPY option	Run the ICKDSF REFORMAT REFVTOC program on the primary volume after the pair is established.	The volume table of contents (VTOC) and indexed VTOC information then reflect the primary volume that is being accessed.
The primary and secondary of this pair is switched at any time	Run the ICKDSF REFORMAT REFVTOC program on the new primary volume	The VTOC and indexed VTOC information then reflect the new primary volume.
The secondary volume is removed from the pair for use as a simplex volume	Run the ICKDSF REFORMAT REFVTOC program on the volume	The VTOC and indexed VTOC information then reflect the correct information for the device.
