As others have stated, automating your IPL process will help alot.
Our shutdown and IPL process are automated. We use NetView for system
automation.
When we need to IPL the operators execute a clist from a system console
on the system they want to shutdown, a WTOR is issued to which they must
reply the SYSID of the system they want to shutdown, which occured prior
to us adding the WTOR. This prevents them from shuting down the wrong
system. The clist then either directly or indirectly (by excuting other
clists) start shutting down everything. The only thing the operations
need to do is the $PJES2.
To IPL they start the process on the HMC. Initial tasks are started
from COMMNDxx and one of those task is the NetView STC used for
automation, it asks the operator what type of IPL is to be performed and
based on that automation starts various other tasks. We have various
types of IPL's depending on why, or where (DR) we are IPL'ing.
We automate the start and stopping of all online systems. If operations
needs to stop a CICS region they execute a clist and pass the task name
of the CICS to be stopped, if they want to stop all production CICS
regions, they execute the same clist but say PROD and all production
CICS regions are stopped.
The only problem we have had since automating most everything is with
the operators selecting the wrong system on the HMC.

This issue has been discuss in multiple places but never in one place.
After a series of human errors in following procedures during an IPL, we
are changing our weekly IPL to semi-annual.
Is there a check list of parameters that I would need to change to
accommodate fewer or no IPLs? Are there control blocks I would need to
be concern with? Will I now run into spool space issues with long
running system tasks?
