because it is in check-stop state. It turns out that the z/OS sysprog
who set up the LPAR had
z/VM 5.3 will IPL in a z/VM mode LPAR on a z10, but it will only use

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
