Execute the following command to activate the md device:
# mdadm -As /dev/md0
mdadm: /dev/md0 has been started with 2 drives.

.
Make sure that the md device has been activated.
In the following example, RAID1 (mirroring) is used for the md device:
# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sdh1[0] sdi1[1]
5238528 blocks [2/2] [UU]
unused devices: <none>
Make sure that md0 : active and the SCSI devices are displayed.

If you need to mount the file systems on the md device, mount them.
Migrating to md Devices for which the MULTIPATH Function Is Used
This section describes the procedure for migrating an environment where md
devices were created on an HDLM device to an environment where the md
devices were created on a SCSI device. The example below describes how to
migrate the md devices created on the HDLM device for which the LINEAR
function is used to the md devices created on the SCSI device for which the
MULTIPATH function is used.
In this procedure, the device /dev/md0 on /dev/sddlmaa1 is migrated to the
device /dev/md0 on /dev/sdh1 and /dev/sdo1. To create the environment
shown in Figure 3-26 Device Configuration When an md Device on an HDLM
Device Is Moved to a SCSI Device (An Environment that Uses the md Device's
MULTIPATH Functionality) on page 3-220 , carry out the procedure below. To
remove HDLM, carry out the steps before the removal.
