z/VM processor mode
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.
Re: z/VM processor mode
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.

Re: z/VM processor mode
Two CP's, no IFLs. The CMS virtual machines worked fine. It wasn't until IPLing the TPF guests that we discovered the issue. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Bruce Hayden Sent: Tuesday, November 18, 2008 12:48 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: z/VM processor mode 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.
