The shaded portion indicates the LDEV information about the LU that is to be

removed from HDLM management.

If setup is being performed for Quorum devices and disk device groups in the LU

that you want to remove from HDLM management, release the LU settings.
When you unregister the SDS or SVM diskset, the diskset data will be deleted so

first back up any necessary data. For details on how to release settings for Quorum

devices and VxVM disk groups, see (2) Remove Sun Cluster Settings of

3.17.2 Preparations for HDLM Uninstallation.
For details on how to release settings for SDS or SVM disksets, see (5) Remove

SDS Settings or (6) Remove SVM Settings of 3.17.2 Preparations for HDLM

Uninstallation.

Edit the HDLM driver unconfiguration definition file (

/opt/

DynamicLinkManager/config/dlmfdrv.unconf

).

Using a text editor, edit the definitions in the HDLM driver unconfiguration

definition file (

/opt/DynamicLinkManager/config/dlmfdrv.unconf

) for

the LU that you want to remove from HDLM management. Based on the LDEV

information of the LU that you want to remove from HDLM management

checked in step 2 (shaded portion), find the target LU in the HDLM driver

unconfiguration definition file (

/opt/DynamicLinkManager/config/

dlmfdrv.unconf

), and delete the hash mark (#) in front of the

LDEV

property

line corresponding to the LU. Deleting the hash mark specifies that the LU

indicated by that LDEV attribute is not to be managed by HDLM.
Figure 4-8: The /opt/DynamicLinkManager/config/dlmfdrv.unconf file (before

editing) and Figure 4-9: The /opt/DynamicLinkManager/config/dlmfdrv.unconf

file (after editing) show examples of editing the HDLM driver unconfiguration

definition file (

/opt/DynamicLinkManager/config/dlmfdrv.unconf

).
