3. Restart the multipath daemon; see Example 12-30.
Example 12-30 Stopping and starting the multipath daemon
[root@palau ~]# service multipathd stop
Stopping multipathd daemon: [ OK ]
[root@palau ~]# service multipathd start
Starting multipathd daemon: [ OK ]
4. Type the multipath -dl command to see the mpio configuration. You see two groups with
two paths each. All paths must have the state [active][ready] , and one group will show
[enabled] .
5. Use the fdisk command to create a partition on the IBM Flex System V7000 Storage
Node disk, as shown in Example 12-31.
Example 12-31 fdisk
[root@palau scsi]# fdisk -l
