3. Creating an HDLM Environment

308

# cat /proc/mdstat
Personalities : [linear]
unused devices: <none>
 

Make sure that 

md0 : active

 is not displayed.

5.

Check the correspondence with HDLM device.
Execute the HDLM-configuration definition utility 

dlmcfgmgr

 with the 

-v

 

parameter specified:

 
# dlmcfgmgr -v
HDevName     Management Device   Host Channel Target Lun
/dev/sddlmaa configured /dev/sdh    1       0      0   0
                        /dev/sdo    2       0      0   1
KAPL10302-I /sbin/dlmcfgmgr completed normally.
 

The 

HDevName

 and 

Device

 columns display HDLM devices and SCSI devices, 

respectively.

6.

Create an md device.
Based on the correspondence between the HDLM devices and SCSI devices 

checked in step 5, create an md device.
When you specify a device name, you must also specify the partition number that 

is displayed in step 2.
Specify all SCSI devices that correspond to HDLM devices:

 
# mdadm -C /dev/md0 -lmp -n2 /dev/sdh1 /dev/sdo1
mdadm: /dev/sdh1 appears to contain an ext2fs file system
    size=5238528K  mtime=Wed Feb  6 20:02:45 2008
mdadm: /dev/sdh1 appears to be part of a raid array:
    level=-1 devices=1 ctime=Wed Feb  6 19:31:04 2008
mdadm: /dev/sdo1 appears to contain an ext2fs file system
    size=5238528K  mtime=Wed Feb  6 20:02:45 2008
mdadm: /dev/sdo1 appears to be part of a raid array:
    level=-1 devices=1 ctime=Wed Feb  6 19:31:04 2008
Continue creating array? y
mdadm: array /dev/md0 started.
 

7.

Create a configuration file.
Execute the following command to add an md device definition to the existing 

configuration file 

/etc/mdadm.conf
