An aclname parameter is available in the TSIDPOL macro when defining BIM-EPIC tape
pools.
If the parameter is not used, BIM-EPIC uses this logic when requesting tape mounts:
Output (Scratch):
Requests the ACL to mount a scratch. If the ACL does not have a scratch cartridge for
the requested pool, BIM-EPIC AVR’s non-ACL drives. If more than one ACL is present,
BIM-EPIC will issue the mount request to each ACL before going to non-ACL drives.
Input:
Asks the ACL if volser nnnnnn is in its inventory. If it is, a mount request is issued. If it
is not, BIM-EPIC AVR’s non-ACL drives. If more than one ACL is present in an
installation, the vendor’s ACL Manager sends the query request to each ACL before
returning to EPIC.
If the parameter is used, for an Output tape BIM-EPIC will only query the ACL specified in
aclname. If that ACL does not have the requested volume, BIM-EPIC will go to the non-ACL
drives for AVRing, bypassing any other ACL’s in the installation. The input logic is as
described, above.
If aclname is used for one pool, it must be used for all ACL-resident pools. When
aclname is present, BIM-EPIC will not check any other ACL for the output tape.
