Functional Differences Between Version 6.2 and Versions

Earlier than 6.2

In HDLM version 6.1.0 or earlier, when you create a system replication

(clone) on another LPAR or host from an mksysb image by using the
mksysb command provided by the OS, you needed to remove HDLM

before executing the mksysb command.
In HDLM version 6.2.0 or later, you do not need to remove HDLM before

executing the mksysb command. You can now execute the HDLM

restoration support utility (dlmpostrestore) after creating a system

replication, so that HDLM information can now be updated according to

the destination system's environment.

For HDLM 6.1.0 or earlier, a physical volume (hdisk) might have been

changed during an unattended upgrade installation or re-installation of

HDLM. For HDLM 6.2.0, a physical volume (hdisk) is not changed during

an upgrade installation or re-installation of HDLM.

Functional Differences Between Version 6.1 and Versions

Earlier than 6.1

In a new installation of HDLM, the default load balancing algorithm has

function has been changed from off to on.
