HSC and Control-M/Tape Mount Messages

Use the following step to implement scratch pooling in your StorageTek Silo:

1. Specify M or Y for the DYNWTO parameter in the CTTPARM member (through Control-M/Tape step 2.2 in ICE). This causes Control-M/Tape to include the name of a scratch pool in the mount messages.
2. Ensure that HSC scratch pool definitions (defined through the HSC’s SCRPOOL initialization statements) are compatible with Control-M/Tape pool definitions.
3. HSC SCRPOOL statements are less flexible than Control-M/Tape pool definitions. Therefore, only Control-M/Tape pools that can also be defined to HSC should be defined (for example, do not use masking characters in pool definitions).
4. HSC does not allow scratch pool names that are more than 13 characters in length. Therefore, pool names of 13 characters or less should be used in Control-M/Tape.
5. Use the SLSUX01 HSC job processing user exit to interpret Control-M/Tape mount messages.
   1. Use the ICE Automatic Exit Installation Tool to compile the SLSUX01 member. For details about this tool, see the exits chapter in the INCONTROL for z/OS Administrator Guide.
   2. Ensure that Exit SLSUX01 is enabled in HSC.
