# chkconfig multipathd on

# chkconfig multid on

# chkconfig multipathd –list

4. Now Search the partition and format it.

# fdisk -l
# fdisk /dev/dm-0
# mkfs.ext3 /dev/mapper/mpath1p1
# mount /dev/mapper/mpath1p1 /var/lib/mysql/

5. Querying the multipath IO status outputs the current status of the multipath maps

# multipath -l
