I did reboot after doing dasd_configure on the disks. dasdfmt didn't work until I did the logon/logoff.

That (logoff/logon) did the trick. Definitely a bug then. You really should report it. It would also be interesting to find out if simply reIPLing Linux works around the problem.

Where to Find kernel changes ?
Inquiring management minds want to know what changes are in a kernel level before we do an update. Is there somewhere this information is available ? We are running SLES11 SP1 (we are new to SuSE). example: going from kernel 2.6.32.12-0.7.1.s390x to 2.6.32.49-0.3.1.s390x where can I find out what has been added/deleted/updated?

MIPS increase after SLES11 SP1 patches
We implemented latest patches on our SLES11 SP1 systems recently Now all the zLINUX guest are using almost 8 - 10 IFL mips extra per Guest - that is increasing our load on the z/VM LPARs by 300 mips . Unfortunately this is not so visible from the guest level and hence difficult to find the culprit process/component. We have around 35 guests per LPAR. I know there is some degree of overhead with patching and security - but this seems excessive. Our workload is primarily websphere/java applications type. I have tried: 1) investigating top/sar etc command and process lists 2) checked Omegamon-can pinpoint nothing yet 3) several linux commands tools to (iostat/mpstat/iptraf etc but can find nothing. Any insight from the gurus? Has anyone noticed this situation? Thanks for going through my long note. Sagar Srivastava ISO, jersey city This email is intended for the recipient only.

Re: MIPS increase after SLES11 SP1 patches
Have you tried using powertop to investigate? Sure the tool was intended on tracking power consumption, but it's very useful for seeing what is waking up your guests. Just a thought...

Re: MIPS increase after SLES11 SP1 patches
If you investigate the ESALNXP report provided by ZVPS, you will see a cron job with your latest patches, and not before that.
