Hello everyone, I have googled this mailing list for a good while and found a lot of useful information. I have a problem that I have not been able to find a solution for, so I have joined the list. It always seemed to be a good place to hang out, I just never got around to it.
We have a central Linux for zSeries NFS server running in an LPAR. (Doing it this way lets NFS stay up even when we put on VM maintenance.) It is currently running under SLES9. Two changes need to be made to this server. First it's disk drives are going off lease, so the data needed to be moved. Second, it is running under SLES9 and I would like it to run under SLES10 SP1. I built the replacement SLES10 system under zVM and practiced my data move procedures. It all worked. Over the weekend, I took down all of necessary systems and unmounted the NFS mounts and brought the SLES9 LPAR down. I then deactivated and activated the LPAR. I changed the IPL address to point to the new storage subsystem and IPLed the SLES10SP1 system. The first time, the IPL got down to where it was activating the disk drives. It was on drive 15 of 30 drives when I got the kernel bug. My boss wanted to do it again and watch it closer this time. This time, it down to where it was activating swap devices in /etc/fstab. Since this HMC is Linux based and he did not know how to do a screen print, he whipped out his digital camera and took a picture of the screen. I have the screen print now. I can key the whole screen in if necessary, but for now here are what might be interesting. ..done starting udevd dev_jumptable[0] [1] == NULL kernel BUG at drivers/s390/cio/device_fsm.c:1291! illegal operation: 0001 [#1] CPU: 0 Not Tainted Process cio (pid:9713, task: 000000003f260710, ksp:000000003e157a38) Krnl PSW : 0404000180000000 00000000003635a2 (ccw_device_bug+0x52/0x54) (Followed by the KRNL GPRS, Krnl Code and the call trace. I can include them also if necessary). The kernel level is 2.6.16.54-0.2.3-default #1. Anyone have any ideas on what to do or who to contact ?
