4. HDLM Operation
323
The shaded portion indicates the LDEV information about the LU that is to be
removed from HDLM management.
3. 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.
4. 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
).
