3. Creating an HDLM Environment

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
• In a two-node configuration, execute the following command to release the
cluster installation mode:
# /usr/cluster/bin/scconf -c -q reset
32. On all nodes in the cluster, add
/opt/DynamicLinkManager/bin
to the
PATH
environment variable in the environment settings files (such as
.profile
) for
root permissions.
When the Bourne or Korn shells is used, add the path as shown below:
PATH=$PATH:/opt/DynamicLinkManager/bin ; export PATH
When the C shell is used, add the path as shown below:
set path=( $path /opt/DynamicLinkManager/bin )
33. Execute the following command to view the HDevName and iLU columns:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
Check the execution results of this command to determine the correspondence
between each HDevName (logical device file name of the HDLM device) and
iLU (the internal LU number). Then, compare the correspondence of the logical
device file names and internal LUs that took place before HDLM was installed,
and then re-register the correct HDLM devices in those programs that will use
