z/VM processor mode

2008-11-18 Thread Quay, Jonathan (IHG)
We moved a z/VM 5.3 703 system from a z/990 to a z/10.  IPLed
successfully.  When we attempted to IPL our TPF 4.1 guests, they would
go through rollcall and then take an HCP1455E CPU XX is not started
because it is in check-stop state.  It turns out that the z/OS sysprog
who set up the LPAR had chosen Z/VM as the processor mode without
realizing exactly what that meant.

z/VM 5.3 will IPL in a z/VM mode LPAR on a z10, but it will only use
1 type of the CPUs.  In my experience I had both CPs and IFLs defined
to the partition, but 5.3 would only use the CPs.  It could see that
the IFLs were there, but they could not be varied online.  What kind
of CPUs were defined to your z/VM mode LPAR?  Maybe it only had IFLs?
But the real answer is to not use z/VM mode unless you're on 5.4.

Two CP's, no IFLs.  The CMS virtual machines worked fine.  It wasn't
until IPLing the TPF guests that we discovered the issue.
