This is with sles9 SP1. During base install, I had DASD 104-108 configured as LVM and everything is OK. Later, I added DASD 109, activated & format it using yast and added it to the same lvm vg. Everything looks OK until you reboot.
At boot time, during LVM activation, DASD 109 is not active, thus LVM fails. Much later, coldplug ccw scan "finds" DASD 109 and then later you can manually activate LVM . Notes: Default SLES9 install does not use parm "DASD= " in zipl.conf. "109" appears in "/sys/bus/ccw/devices/*" and "/etc/sysconfig/hardware/*" How can I make LVM reliably come up at boot time.
