HP XP Racks - Manual (Page 106)

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.
To inherit the mapping between virtual target devices and HDLM devices
on the virtual I/O server, specify the -e parameter to inherit the existing
hdisk configuration.
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)

KAPL10531-I The status of all of the HDLM drivers was changed to
"Defined".
To inherit the existing hdisk configuration when the version of the
installed HDLM is 6.2 or later:
# /usr/DynamicLinkManager/bin/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)

KAPL10531-I The status of all of the HDLM drivers was changed to

To avoid inheriting the existing hdisk configuration:
# /usr/DynamicLinkManager/bin/dlmrmdev -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
hdisk7 deleted
