Is strange, we continue the installation with the errors. It finishes and after reboot the server it install all without the LVM's.

Multiple migration products visible to zypper prior to SP2 upgrade to SP3
Hello listers, We are still in midst of upgrading our last SLES11SP2 system. We have made several attempts on this system. We have tried Suse Manager. We have tried SMT. We have tried wagon. And we have tried various repositories. SMT and Suse Manager. We are investigating using the zypper method this time. I am examining the zypper method as outline in Suse Knowledge base article 7102368. And the active repositories belong to suse manager. The system is at SLES11SP2. But the repositories may not exactly reflect that. For example, when I issue a zypper se -t product | grep -h -- -migration | cut -d\| -f2 I get SUSE_SLES-SP2-migration SUSE_SLES-SP3-migration Is this going to cause problems later on when I issue I start the actual migration and I issue the commands for real. Will the SP2 migration product be gone, or should I install it, or should I just leave it be.

Re: IFL vs Non-IFL processor
Steve, You might be able to tell with hyptop under Linux, from the man pages, the first line shows: CPU TYPES Depending on the hypervisor different CPU types are supported. These CPU types can be selected either interactively or with the --cpu_types command line option. The calculation of the CPU data only uses CPUs of the specified types. On LPAR the following CPU types are supported: 'IFL' - Integrated Facility for Linux 'CP' - CP processor type 'UN' - Unspecified processor type (other than CP or IFL) NOTE: It is possible that on older machines also IFLs are shown as CPs. On z/VM currently only the processor type 'UN' is available.

How about QUERY CPUS: # *vmcp q cpus* CPU 00 ID FF0777188000 (BASE)* IFL* CPUAFF ON On Fri, Feb 20, 2015 at 2:01 PM, Michael O'Reilly mik...@us.ibm.com wrote: Steve, You might be able to tell with hyptop under Linux, from the man pages, the first line shows: CPU TYPES Depending on the hypervisor different CPU types are supported. These CPU types can be selected either interactively or with the --cpu_types command line option. The calculation of the CPU data only uses CPUs of the specified types. On LPAR the following CPU types are supported: 'IFL' - Integrated Facility for Linux 'CP' - CP processor type 'UN' - Unspecified processor type (other than CP or IFL) NOTE: It is possible that on older machines also IFLs are shown as CPs. On z/VM currently only the processor type 'UN' is available.

I could verify that the IFLs were being used with zvm commands. With this one, I know we have an IFL that has been dedicated to this Lpar. I was just curious if there are messages or commands within the zLinux environment that verified that it is now using an IFL processor. A command or a message would be helpful. If not, no worries. Thanks.

Are there message(s) or indicators at Linux startup that tells me that I'm running on an IFL processor? Not that I'm aware of. I believe the only way to tell is from the HMC. Since you don't seem to have had Linux for System z before, I'm curious as to whether you even have any IFLs in your box. And if not, why look for such a message? (Trying to understand why you're asking, maybe there's really something else you want/need to know.)

Re: IFL vs Non-IFL processor
I doubt that they expose the difference between an IFL and a GP (General Purpose) engine as an IFL, basically, is a GP engine loaded with different microcode (to prevent the engine from being able to run z/OS). It is a full speed engine where a GP engine can be slowed down, via microcode, to reduce software licensing costs in a z/OS environment.

I don't see anything obvious in /proc or /sys that would provide such information. I don't know if that means it's information IBM does not want to make publicly available, or if the IBM developers just never bothered to expose it. It might be worth asking your IBM rep. about it.
