Guaranteed Space Attribute

When MOVE/COPY is processing VSAM data sets, CA Disk honors the Storage Class attribute Guaranteed Space under the following conditions:

1. The TOVOL= DSCL parameter is used to determine the volume(s) to which the data set is to be moved or copied. However, the volume(s) must be accepted by SMS's ACS routines.
2. Unlike MOVE/COPY in other situations, all volumes specified on the TOVOL= parameter are used to allocate the new data set. For example: If you specify three volumes as TOVOL=(VOL001,VOL002, VOL003), the resulting data set will be allocated on three volumes. If you specify TOVOL=VOL/, the resulting data set will reside on as many volumes as matches the VOL/ mask. In other words, to MOVE or COPY, it does not matter how many volumes the data set resides on.
3. The NEWVOLUMES parameter should always be coded in order to obtain correct results. If NEWVOLUMES is omitted, CA Disk can attempt to include some of the current source volumes in the list of volumes for the new data set. This is unlikely to be desirable for these allocations.
4. The VATHRESH parameter is ignored.
5. You must use an explicit FIND statement to select these data sets.
