3.5.5 Performing an Upgrade Installation or Re-installation of HDLM

This subsection explains how to perform an upgrade installation from an earlier

version, or how to re-install HDLM.

Because HDLM version 5.8.1 or earlier cannot be upgraded to HDLM version 5.9 or

later, migration is necessary. For details about migration, see 3.5.6 Migrating from

HDLM Version 5.8.1 or Earlier to Version 5.9 or Later.

(1) When Installing HDLM in a Local 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

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

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.
