If it becomes necessary to shut down a coupling facility containing
the SYSZWLM_WORKUNIT structure (either to apply maintenance or to
reconfigure), there are two options:
If another coupling facility has enough storage available, use
the XES system-managed rebuild function to rebuild the SYSZWLM_WORKUNIT
structure into another coupling facility. See z/OS MVS System Commands for
more information.
If there is no other coupling facility into which the SYSZWLM_WORKUNIT
structure can be rebuilt, the structure will be deleted when its coupling
facility is shut down and therefore multisystem enclave support will
be disabled (as described in Coupling facility failures).
An installation should take the appropriate steps to quiesce any
active work which may be using multisystem enclaves before shutting
down the coupling facility containing the SYSZWLM_WORKUNIT structure.
