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

471

• 4.6.1 Notes on changing the configuration of the HDLM operating

environment

• 4.6.6 Changing the configuration of an HDLM device

• 4.6.7 Reconfiguring an HDLM device without changing its name

 Eliminating the rc.shutdown file

HDLM version 5.8.1 or earlier provided an

rc.shutdown file in order to avoid

having physical volumes already defined when a host is started. Because this

situation does not occur in HDLM version 5.9 or later, the

rc.shutdown file is

no longer provided. For this reason, the manual has been changed as follows:

• Section 3.3.13 Notes on Starting a Host in the manual HiCommand Dynamic

Link Manager User's Guide (for AIX(R)) (3000-3-926-50(E)) has been

deleted because it explained the editing method for the

rc.shutdown file.

• The portion of the procedure related to the

rc.shutdown file has been

deleted from the explanation of uninstalling HDLM.

• The

rc.shutdown file has been deleted from the files collected by the

DLMgetras utility for collecting HDLM error information.

 The content displayed for HDevName in the HDLM view command operation has

been changed from the HDLM device (

dlmfdrvn) to hdisk. Accompanying this

change,

Device for displaying hdisk name when view -lu or view -drv is

executed in HDLM version 5.8.1 or earlier has been removed.

 Because dlmfdrv was deleted, the following HDLM utilities are no longer

provided and the descriptions related to them have been deleted from the manual:

• Utilities for operating HDLM volume groups

HDLM version 5.9 or later uses standard AIX commands that correspond to

the commands for utilities for operating HDLM volume groups. Table

Table B-1: Commands of the utilities for operating HDLM volume groups,

and corresponding AIX commands lists the correspondence between the

commands for operating utilities for HDLM volume groups and the standard

AIX commands.
