The operator usually takes a stand-alone dump in a sysplex when
an MVS™ system is not responding.
Situations that indicate that stand-alone dump should be run include:
- Consoles do not respond
- MVS is in a WAIT state
- An MVS system is in a “status
update missing” condition and has been or is waiting to be removed
from the sysplex
- A stand-alone dump has been requested by Level 2.
There are two high-level methods for taking a stand-alone dump
of an MVS system that resides
in a sysplex. Both methods emphasize the expeditious removal of the
failing MVS system from the sysplex.
If the failed MVS system is not
partitioned out of the sysplex promptly, some processing on the surviving MVS systems might be delayed.
