6. Delete the kernel parameter you added in step 2 from the boot loader
configuration file.
If the boot loader configuration file contains any entries other than the entry for
using HDLM as a boot disk, make sure that
root=
HDLM device is not specified
as a kernel parameter, and then go to step 9. If
root=
HDLM device is specified
as a kernel parameter, go to step 7.
7. Execute the HDLM-configuration definition utility (
dlmcfgmgr
) with the
-v
parameter specified to check the relationship between the HDLM device and
SCSI device.
# dlmcfgmgr -v

KAPL10302-I /sbin/dlmcfgmgr completed normally.
The
HDevName
column displays HDLM devices and the
Device
column displays
SCSI devices.
If the HDLM device corresponds to more than one SCSI device, specify the SCSI
device that appears first. In this example,
/dev/sda
indicates a SCSI device.
8. In the boot loader configuration file, replace
root=
HDLM-device with
root=
SCSI-device.
Replace the HDLM device with the SCSI device you determined in step 7.

command or

command to make sure that the root
directory (

) is the HDLM device.
