Based on the results of step 25, compare the logical device file names
from before and after the HDLM installation, and re-register the correct
HDLM devices in programs that use HDLM devices.
After you have checked the HDLM operation, repeat steps 27 to 30 below
on all nodes.

.
Remove the device ID information of devices that do not exist. Execute
the following command:
# /usr/cluster/bin/scdidadm -C
28
.
Assign device IDs. Execute the following command:
# /usr/cluster/bin/scdidadm -r
29
.
Notify the server of the new device ID information. Execute the following
command:
# /usr/cluster/bin/scdidadm -ui
30
.
Update the Sun Cluster global device namespace. Execute the following
command:
# /usr/cluster/bin/scgdevs
31
.
To use an HDLM device for a Quorum device, specify the Quorum device
settings at any of the nodes that constitute the cluster.
The following shows examples of executing the commands:
¢
Check the device ID of the HDLM device.
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
# /usr/cluster/bin/scdidadm -L
¢
Set up the Quorum device.
# /usr/cluster/bin/scconf -a -q globaldev=d4
