(2) When Installing HDLM in a Boot Disk Environment
1. Log in to AIX as a user with root permissions.
If you are using a virtual I/O server, see the virtual I/O server documentation to
log in to AIX.
2. Back up the HDLM settings.
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.
• Save the HDLM environment settings information.
# /usr/DynamicLinkManager/bin/dlnkmgr view -sys >
any-file-name
Make sure that the license has not expired.
• Save the HDLM execution environment ODM settings.
# /usr/DynamicLinkManager/bin/dlmodmset -o >
any-file-name
3. Execute the following command to unmount the file system used by HDLM.
# umount
file-system-mount-point
4. Execute the following command to display all the activated volume groups.
# lsvg -o
5. Among the displayed volume groups, inactivate the volume groups used by
HDLM.
# varyoffvg
volume-group-name
