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

474

The

dlmpreuninst

utility excludes, before you uninstall HDLM, the hdisk

recognized as a boot disk from being an HDLM management-target device.

B.6 About Settings when Upgrading the OS

(1) Eliminating Settings when Upgrading the OS

There is no required procedure in HDLM for when the OS is upgraded, so the

explanation in (1) Settings for an OS Upgrade in 4.6.2 Settings for an OS Upgrade in

the manual HiCommand Dynamic Link Manager User's Guide (for AIX(R))

(3000-3-926-50(E)) is no longer necessary and has been deleted from this manual.

(2) Eliminating Settings when Changing the Kernel Mode

In HDLM version 5.9 or later, both 32-bit and 64-bit versions are installed. When the

32-bit kernel is in use, the 32-bit version of HDLM is used automatically, and when

the 64-bit kernel is in use, the 64-bit HDLM is used automatically. Because of this

change, the following sections have been deleted from the manual HiCommand

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

3.4.1 Preparations for a New Installation of HDLM

(4) Switch the kernel mode

4.6.2 Settings for an OS Upgrade

(2) Settings when the kernel mode is changed

Because of the changes explained in (1) Eliminating Settings when Upgrading the OS

and (2) Eliminating Settings when Changing the Kernel Mode, the

dlmchenv

utility

for modifying the HDLM execution environment is no longer necessary and has been

deleted.

B.7 Changing a Virtual I/O Server's Method of Recognizing Virtual

SCSI Disks

In HDLM version 5.8.1 or earlier, either PVID or

unique_id

can be selected as the

method used by a virtual I/O server for recognizing virtual SCSI disks. In HDLM

version 5.9 or later, only

unique_id

can be used because of the MPIO specification.

Because of this change, the explanation in 4.1.11 Switching the recognition method for

virtual SCSI disks when the virtual I/O server is used in the manual HiCommand

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

deleted because it is no longer necessary. Also, the

-u

and the

-e

parameters of the

dlmodmset

utility for setting the HDLM execution environment ODM are no longer

provided because they are also not necessary.
