Perform installation according to the documentation for relevant products
(packages).
4 Back up the currently used initial RAM disk image file for HDLM.
.
5 Execute the dlmmkinitrd utility (utility for supporting a boot disk) with
.
the -f parameter specified to create an initial RAM disk image file for
HDLM.
For the parameter, specify the initial RAM disk image file name that is
currently used.
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
/dev/sddlmaa
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.
