It depends on how you start z/VM
- With a SHUTDOWN REIPL or an IPL after a CP abend (does that still
happen???), CP uses the IPLPARMS
- If you use the HMC (or SE) to "load" z/VM into the LPAR, the start is
the contents of the LOADPARM field of the HMC. If that contains. For
example:
- "CONSxxxx", you explicitely ask to start CP with xxxx as console
- "xxxx" you request that SAPL is started on xxxx
- "blank", SAPL does not display a panel, but loads CP with the
defaults IPLPARMS set when SAPL was written. You can see these
defaults by
starting SAPL. For example (with a "standard" VM setup):
- Logon to MAINT
- DETACH 122-130
- LINK * 123 123 RR <-- assure CP resident is R/O
- Q V CONS <-- get address of virt console (often
0009)
- SYSTEM RESET <-- kill CMS
- TERM CONMODE 3270
- IPL 123 LOADPARM vvvvv (e.g. 0009)
To change the SAPL default parameters, use SALIPL (or Mike Walter's
MKSALIPL EXEC), SALIPL lives on MAINT 193.
