Make sure that the key used for disk reservation has been registered for
the LU newly recognized by the node.
Execute the following command on any node:
# /usr/cluster/lib/sc/scsi -c inkeys -d the-name-of-the-logical-
device-file-on-slice-2-of-the-LU-newly-recognized-by-the-node
The following shows an example of executing the command:
# /usr/cluster/lib/sc/scsi -c inkeys -d /dev/rdsk/
c3t50060E80033A9902d2s2
Add the new LU to HDLM by following the steps in Adding a New LU By
Restarting the Nodes (When Using Sun Cluster) on page 4-25 beginning
with step 5. Even when you release the setup for Quorum devices and
disk device groups, since the key used for disk reservation will remain
registered, you will need to restart the node in non-cluster mode and
unregister the key.
If the key is not displayed, perform the steps beginning with step 5.

Make sure that the logical device files for the sd or ssd devices are backed
up.
When you execute the dlmcfgmgr utility in step 8 after executing the
dlmsetconf utility in step 6, since the logical device files of the sd or ssd
devices to be managed by HDLM will be deleted, make sure that you back
up these files beforehand. For details on how to back up files, see step 4
in Performing Operations on Devices to Be Managed by HDLM on page
3-45 of Preparations for a New Installation of HDLM on page 3-45 .

Use the following dlmsetconf utility to create the HDLM driver
configuration definition file (/kernel/drv/dlmfdrv.conf) and the HDLM
driver unconfiguration definition file (/opt/DynamicLinkManager/config/
dlmfdrv.unconf):
# /opt/DynamicLinkManager/bin/dlmsetconf
The device mentioned in Devices Managed by HDLM on page 2-3 will be
set to be managed by HDLM.
When the dlmsetconf utility is executed, the KAPL10242-I message will
be output.
If you respond by entering y, when you run the dlmcfgmgr utility in step
8 after running the dlmsetconf utility, the logical device files of the sd or
ssd devices to be managed by HDLM will be deleted. If the logical device
files are already backed up, respond by entering y and running the
dlmsetconf utility. If the files are not backed up, respond by entering n,
and then cancel processing for the dlmsetconf utility. Then, backup the
logical device files by referring to step 4 in Performing Operations on
Devices to Be Managed by HDLM on page 3-45 of Preparations for a New
Installation of HDLM on page 3-45 , and then execute the dlmsetconf
utility.
