I have taken a step back a bit on this project. The boot disc is device /dev/sda1, main '/' root file system is /dev/sdb1. Both of these are scsi devices but no multipath-tools service. I created a third lun for those directories on the '/' filesystem that I need to have some size control ability using LVM.
So I have three scsi Luns. /dev/sda1 non multipath /dev/sdb1 non multipath /dev/mapper/lun0a has multipath and LVM filesystems on it. These luns were connected to an existing SLES9 SP3 built on ECKD dasd. Mounted on a mount point on the Linux and all directories were copied from the old system to the new system. /etc/zipl.conf /etc/fstab were modified on the new SCSI disc to support the new layout. mkinitrd and zipl -V were done as chroot to the new SCSI disc. When I IPL the scsi device I get the same message I did before except now the device is non multipath and non lvm. It says it cannot find the root filesystem /dev/sdb1. The same odd thing happens here where the /dev/sdb1 root device name changes to /dev/sdg ? It appears the device names are changing. I have set a rule in /etc/udev/udev.rules as shown in the book to set persistent device names for /dev/sd? between IPLs. It looks like the device names are not persistent. I also see the multipath has now picked up the two devices I blacklisted in multipath.conf. /dev/sda and /dev/sdb now show in the multipath -l display as different device names. Anyone seen this problem or have any thoughts it would be appreciated.
