IPL without OPERATOR on console
Hello List, Last week we have seen an IPL that did not go the way I'd expected. It went OK, so VM is running, but it doesn't feel right. In the past our IPL procedures were: - Connect a terminal session to a console (let's say device 820) - load the LPAR on HMC with loadparm 820. - On the console the SA-IPL appears. - Change parameters if required and press PF10. - On the console user OPERATOR is logged on and some information on IPL i s displayed on the console. - User OPERATOR runs PROP and disconnects. Our new VM runs on a z9 machine. (actually 6 VM's on two machines) The IP L now looks like this: - Connect terminal - load LPAR - console turns to the VM logon screen. No SA-IPL, so also no way to specify a PROMPT or a different PARM disk. N o user OPERATOR to ask for start parameters (WARM, NOAUTOLOG) or to display the IPL steps, such as SPOOL init, and things like that. When closing the console log for operator I can see the lines I would expect to see on the console so it did all those things but it didn't show us that. It only happens on a z9 machine. Our VM's on z890 and z990 machines do show the SA-IPL during IPL. All VM's are z/VM 5.2 and use basically the same system config. So it looks like it has something to do with the machine or its configuration. Has anyone ever seen this? Any ideas as to what the cause would be? TIA, Berry van Sleeuwen.
Re: IPL without OPERATOR on console
There had to be a configuration change between the old machine and the z9. VM won't behave that differently just because of different hardware.

Re: IPL without OPERATOR on console
by any chance did SYSTEM CONFIG have changes to AUTO_WARM_IPL and other such parms? Is loadparm being specified on the new hmc?

Re: IPL without OPERATOR on console
Kris, The VM is z/VM 5.2 RSU 601. I can test it with one LPAR that still needs to be IPLled. We have cloned some VM's so apart from some small local tailoring (like nodeID and TCPIP configs) the VM's are identical. Let's play around a little bit. Either a s guest or native. You mention drag 'n' drop in the HMC. Does that indeed mean that the SA-I PL in that case is bypassed and VM is IPLled using defaults (CPLOAD MODULE, MAINT CF1 etc)? I must say, I haven't seen an HMC up close in 4 years now because that is completely separate from our department and even located in a different building. My last HMC was the one on a 9672. It is a real pleasure I must be able to help our operators during IPL but to have no recent knowledge of the newer HMC and it's procedures and capabilities :- (. Regards, Berry.
Re: IPL without OPERATOR on console
The dragdrop is simply the way to give an LPAR an integrated 3270 console. It does not instruct SAPL to display/bypass its panel. The display of the SAPL panel is requested by entering the address of a 3270 in the LOADPARM field (enter SYSG to indicate the integrated 3207 console) When the LOADPARM field is empty, you tell SAPL that it should use the defaults to IPL CP. These defaults are defined by the SALIPL command (i.e. SALIPL writes the SAPL program and the IPL defaults on the disk). From your forum appends, I seem to conclude that you have operator intervention during all IPLs. The normal way to IPL a VM is with an empty LOADPARM field, which means no operator intervention is required. Entering a 3270 address in the LOADPRAM field is only required when you want to IPL VM in a special way: such as: another console, an other CP nucleus than CPLOAD, another SYSTEM CONFIG file. At my customer's installation, we can use a browser to connect to the HMC and so I can IPL VM from my desk, or even here at home if the operators would get stuck. But, I must admit, before or VMs were moved from a 9672 to a z9, I never saw an HMC. The last machine I IPLed myself before the z9 was a 9370, and the HMC was called hardware console at that time. -- Kris Buelens, IBM Belgium, VM customer support 2007/5/24, Berry van Sleeuwen [EMAIL PROTECTED]: Kris, The VM is z/VM 5.2 RSU 601.
