Koray, Did you try to IPL 102 and see if it comes up. Is the /boot is also on Minidisk 102 as well? You also should mount "/dev/dasda1 to /mnt " to see if the "/boot" is still on that partition.

So i thought it's about ZIPL configuration but there was nothing wrong there. I regenerated the bootmap again by running /sbin/zipl, and tried to reipl from Minidisk100, but no luck. Now lets see what's weird; When i first installed SLES, the disk mapping was: Minidisk100 - dasda - /boot Minidisk101 - dasdb - swap Minidisk102 - dasdc - / Minidisk110 - dasdd - LVM Member ... Minidisk209 - dasdn - LVM Member But when i boot with cd, and activate the DASD's i see Minidisk100 - dasda Minidisk101 - _dasdn_ Minidisk102 - dasdb Minidisk110 - dasdc ... It seems the mapping has changed somehow. But when i run the installed system from DVD menu, i see DASD's as they supposed to be: linux101:~ # more /proc/dasd/devices 0.0.0100(ECKD) at ( 94: 0) is dasda 0.0.0101(ECKD) at ( 94: 4) is dasdb 0.0.0102(ECKD) at ( 94: 8) is dasdc 0.0.0110(ECKD) at ( 94: 12) is dasdd 0.0.0200(ECKD) at ( 94: 16) is dasde 0.0.0201(ECKD) at ( 94: 20) is dasdf 0.0.0202(ECKD) at ( 94: 24) is dasdg 0.0.0203(ECKD) at ( 94: 28) is dasdh 0.0.0204(ECKD) at ( 94: 32) is dasdi 0.0.0205(ECKD) at ( 94: 36) is dasdj 0.0.0206(ECKD) at ( 94: 40) is dasdk 0.0.0207(ECKD) at ( 94: 44) is dasdl 0.0.0208(ECKD) at ( 94: 48) is dasdm 0.0.0209(ECKD) at ( 94: 52) is dasdn linux101:~ # more /etc/fstab /dev/disk/by-path/ccw-0.0.0101-part1 swap swap /dev/disk/by-path/ccw-0.0.0102-part1 / ext3 /dev/system/home /home /dev/system/opt /opt /dev/system/tmp /tmp /dev/system/usr /usr /dev/system/var /var proc /proc sysfs /sys debugfs /sys/kernel/debug devpts /dev/pts linux101:~ # more /etc/zipl.conf # Modified by YaST2.

HCPGIR450W ... I re-run ZIPL but, no change, it still searches 0.0.0100 for root fs. I think the reason is same with the first DASD activation menu with DVD. Linux somehow sees diskmaps different and i cant change the ZIPL behaviour. Now, i need to change ZIPL to mount root-fs from Minidisk102. And then research why the Minidisk-Linux Dasd mapping is changing. Sorry for the long mail and thanks for your patient.
