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
HDevName Management Device Host Channel Target Lun
/dev/sddlmaa
configured /dev/sda 2 0 0 0
/dev/sdb 2 0 1 0
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.

In this example, replace the HDLM device with root=/dev/sda2.
9. Restart the host.
10. Use the
mount command or vgdisplay command to make sure that the root
directory (
/) is the HDLM device.
