# chkconfig –add multipathd
# chkconfig multipathd on
# reboot
For each lun assigned to you a device under /device/mapper will apear, do a fdisk to each one:
# fdisk /dev/mapper/360060e80047656000000765600000e43
# fdisk /dev/mapper/360060e80047656000000765600000e44
# fdisk /dev/mapper/360060e80047656000000765600000e45
# fdisk /dev/mapper/360060e80047656000000765600000e46
# fdisk /dev/mapper/360060e80047656000000765600000e47
# fdisk /dev/mapper/360060e80047656000000765600000e48
# fdisk /dev/mapper/360060e80047656000000765600000e49
In each case do a “p” and then a “w” to overwrite the volume label, you will have to restart the server.
# reboot
Once back, open the lvm assistant:
# /usr/bin/system-config-lvm
once there initialize each block device found at:
# ls /dev/dm*
after that you can create a volume group and volumes 🙂
