Hitachi Dynamic Link Manager Software Users Guide for AIX (6.6) (T5208-96010, April 2011)

B. Differences Between HDLM Version 5.9 or Later and Version 5.8.1 or Earlier

B.2 Simplifying the HDLM Environment Configuration and
Operation Procedures by Changes to the Logical Device Files
 The logical device files that can be controlled by the HDLM driver have been
unified from HDLM devices (
dlmfdrvn) to the hdisk provided by the OS.
Therefore, logical device files controlled by HDLM can be configured by AIX's
standard
cfgmgr command.
Both the file that defines non-HDLM-managed disks (
/usr/
DynamicLinkManager/drv/dlmfdrv.unconf
) and the file that defines the
HDLM driver configuration (
/usr/DynamicLinkManager/drv/
dlmfdrv.conf
) are no longer used. After installing HDLM, all devices shown
in Devices that HDLM can manage in 2.1 Devices Managed by HDLM will be
managed. You cannot exclude physical volumes from HDLM-managed targets.
Accompanying these changes, the following deletions have been made from the
manual HiCommand Dynamic Link Manager User's Guide (for AIX(R))
