Hello experts!

After reboot OS failed mount /dev/mapper/oradata

OS: SUSE 10 sp4 ppc64
SAN: DS5300

My steps how i add the LUN:
1) rescan-scsi-bus.sh
2) vi /etc/multipath.conf
defaults
{
user_friendly_names no
}

multipaths {

multipath {
wwid 3600a0b80006e6a66000040a95066a18b
alias oradata
}
3) fdisk /dev/dm-2
4) echo 'add' > /sys/block/dm-2/uevent
5) /sbin/mkfs.reiserfs /dev/dm-2
6) mkdir /oradata
7) vi /etc/fstab
/dev/mapper/oradata /oradata reiserfs acl,user_xattr 1 2
8) mount –a
