Extend IOVF for Offline EXTEND command
If the necessary space is not present, allocate volumes to the area data set by using IDCAMS ALTER ADDVOLUME.
Be sure to revise the DBD to increase IOVF so that subsequent offline processes (such as CHANGE or UNLOAD/RELOAD) do not use the old ACB and decrease the amount of IOVF space.

Area PFPSAMP1 is identified on the EXTEND statement, and is dynamically allocated from its dynamic allocation member in the IMSVS. DFSMDA data set in the STEPLIB concatenation.
If you have a license for the BMC Fast Path Analyzer/EP product, quick (checksum) pointer validation is performed on area PFPSAMP1 by default. This pointer validation is performed by default, even if you do not specify it explicitly.
Adding 50 units of work to IOVF increases space for IOVF. Increasing space in this manner allows you to perform a DBD change of the UOW value at a later time.
During the area extend, an output image copy is taken simultaneously using standard storage and disposition parameters. The DBD and area name are substituted in the image copy data set name to create a unique name for each area.
