HDLM devices are listed in the
HDevName
column, and SCSI devices are listed
in the
Device
column.
2. Check the
/etc/crypttab
file's second field.
• If a SCSI device is directly specified, change the SCSI device in the
/etc/
crypttab
file's second field to the corresponding HDLM device that was
checked in step 1, and then go to step 4.
The following shows an example of editing the
/etc/crypttab
file's
second field:
Before editing:
luks-volume1 /dev/sdh /etc/cryptpassword1
After editing:
luks-volume1 /dev/sddlmaa /etc/cryptpassword1
• If the device name is specified in UUID format, go to step 3.
3. Execute the following command to check the correspondence between the UUID
and the device name.
# blkid -t UUID="050f9901-3ab8-4556-a091-9c6e4a404f09" -l -o
device
/dev/sdh
#
• If you have an HDLM device name as the output, change the UUID to the
HDLM device name in the
/etc/crypttab
file's second field.
• If you have got a SCSI device name as the output, check the output of step 1
to confirm the HDLM device name corresponding to the SCSI device name,
and change the UUID to the HDLM device name in the
/etc/crypttab
file's second field.
The following shows an example of changing the setting in the
/etc/crypttab
file's second field.
