Because DFSMShsm supports the use of DFSMS sysplex names for the
MIGRATE SYSTEM/SYSPLEX NAME, BACKUP SYSTEM/SYSPLEX NAME, and DUMP
SYSTEM/SYSPLEX NAME storage group system name attributes, it handles
each storage group for automatic space management, data availability
management, and automatic dump processing as follows. How the storage
groups are handled is referred to as the
"system affinity" or
"host
affinity."
- If the storage group system name is a system name, the storage
group is processed by that specific system.
- If the storage group system name is blank, the storage group can
be processed by any system.
- If the storage group system name is a sysplex name, the storage
group is processed by a subset of systems.
Each automatic function (automatic space management, data availability
management, or automatic dump processing) is processed independently.
Therefore, the various systems used by one automatic function will
not affect the other automatic functions.
