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
