IRLMGRP=xcf_group_name parameter for procedures
Use the IRLMGRP=xcf_group_name parameter in procedure to specify the name of the XCF group to which this IRLM belongs.
All IRLMs in the same group must specify the same LOCKTAB parameter and an IRLMID value that is unique within the group. The default is IRLMDS.
The group name (IRLMDS by default) is used as the XCF group name. This name cannot start
with SYS
and cannot be the same as the LOCKTAB parameter.
