3. Creating an HDLM Environment
240
# mdadm -Ss /dev/md0
11. Make sure that the md device has been deactivated.
In the following example, RAID1 (mirroring) is used for the md device:
# cat /proc/mdstat
Personalities : [raid1]
unused devices: <none>
Make sure that md0 : active is not displayed.
12. Install HDLM.
Perform steps 2 to 11 in 3.6.2 Performing a New Installation of HDLM.
13. Check the correspondence between the HDLM devices and SCSI devices.
Check the correspondence by executing 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/sddlmab
configured /dev/sdi 1 0 0 1
KAPL10302-I /sbin/dlmcfgmgr completed normally.
The HDevName and Device columns display HDLM devices and SCSI devices,
respectively.
14. Edit the configuration file.
Based on the correspondence between the HDLM devices and SCSI devices
checked in step 13, change the SCSI device names on the
DEVICE line to the
HDLM device names.
Before the correction:
DEVICE /dev/sdh1 /dev/sdi1
After the correction:
DEVICE /dev/sddlmaa1 /dev/sddlmab1
When you edit the DEVICE line, change only the device names. Do not change the
partition numbers.
15. If the disk partition type of the HDLM device is
fd, change the type to 83.
