3. Creating an HDLM Environment
239
For details about the contents of the configuration file, see the Linux
documentation or use the
man
command.
If you created a new configuration file, go to step 9.
7. If you have already used a configuration file (
/etc/mdadm.conf
), delete the
unnecessary
ARRAY
line in that configuration file.
Delete the
ARRAY
line that includes the same name as the md device name (
md0
)
created in step 6. In the following example, the underlined lines are to be deleted.
# cat /etc/mdadm.conf
DEVICE /dev/sdh1 /dev/sdi1
DEVICE /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1
ARRAY /dev/md0 level=raid1 num-devices=2
UUID=e39a6b15:32e48a5d:ca05f4db:25bc8af9
ARRAY /dev/md0 level=linear num-devices=1
UUID=426a9f1c:9cfa6310:6aa9a80b:11ea2102
8. If you have already used a configuration file (
/etc/mdadm.conf
), edit the
DEVICE
lines.
If the existing
DEVICE
lines include SCSI devices that are specified in the
DEVICE
lines created in step 6, edit the
DEVICE
lines to exclude the SCSI devices.
The following are examples of editing the lines:
Before the correction:
DEVICE /dev/sdh1 /dev/sdi1
DEVICE /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1
After the correction:
DEVICE /dev/sdh1 /dev/sdi1
DEVICE /dev/sdf1 /dev/sdg1
9. Edit the
/etc/mdadm.conf
file to add
auto=yes
to the
ARRAY
line in the
configuration file:
DEVICE /dev/sdh1 /dev/sdi1
DEVICE /dev/sdf1 /dev/sdg1
ARRAY /dev/md0 level=raid1 num-devices=2
UUID=e39a6b15:32e48a5d:ca05f4db:25bc8af9 auto=yes
10. Execute the following command to deactivate the md device.
