If an upgrade installation or re-installation fails, AIX automatically
uninstalls HDLM, and the HDLM settings are deleted.
Perform this step so that a copy of the HDLM settings is available in this
case.
If an upgrade installation or re-installation fails, perform a new
installation, and then re-execute setup to reflect the settings that have
been backed up.

Reconfigure the HDLM device. To automatically perform processes
required for the reconfiguration, such as unmounting the file system and
changing the volume group statuses, go to step 3. To manually perform
these processes, go to step 4.
3 Execute the utility for removing HDLM devices (dlmrmdev) with the -A
.
parameter specified.
To inherit the existing hdisk configuration, execute the dlmrmdev utility
with the -e parameter specified. If you execute the dlmrmdev utility
without the -e parameter specified, the existing HDLM device is deleted.
Note that if you want to inherit the existing hdisk configuration when the
installed HDLM version is earlier than 6.2, use the dlmrmdev utility
included in the installation DVD-ROM of the HDLM version to be installed.
When dlmrmdev is executed, a message is displayed asking you to
continue processing. Enter y to continue processing.
To inherit the existing hdisk configuration when the version of the
installed HDLM is earlier than 6.2:
# /directory-in-which-the-DVD-ROM-is-mounted/HDLM_AIX/hdlmtool/
dlmrmdev -e -A
KAPL10528-I The volume group will be made inactive, and the file
system that is using HDLM will be unmounted. Is this OK? [y/n]:y
KAPL10526-I An attempt to unmount the file system has succeeded.
(file system = /mnt/fs01)
KAPL10527-I An attempt to inactivate the volume group has
succeeded. (volume group = vg01)
