3. Creating an HDLM Environment

263

Set up a Quorum device at any of the nodes that constitute the cluster.
Check the device ID of the sd or ssd device, which is used for the Quorum device.

The following shows an example of executing the command:

# /usr/cluster/bin/scdidadm -L

Set up a Quorum device. The following shows an example of executing the

command:

# /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

When you are using volume management software, specify the settings for the

disk device group.
If you are using SDS or SVM, you must re-create the diskset. For details on how

to re-create a diskset, refer to the Sun Cluster documentation.
If you are using VxVM, you can use a VxVM disk group that was used with

HDLM. To use such a VxVM disk group, re-register it in Sun Cluster's disk

device group. To re-register it, import the VxVM disk group to any node in the

cluster, and then use the

scsetup

utility to register the Sun Cluster disk device

group (see (1) VxVM Settings of 3.17.4 Settings Needed After HDLM

Uninstallation). For details, refer to the Sun Cluster documentation.

(5) File System Settings

For the file systems of the LUs that were managed by HDLM, specify settings that

allow the Solaris

ssd

driver to be mounted or specify settings that allow volume

manager's volumes to be mounted after setup is performed again.
After uninstalling HDLM, the ZFS file system that was exported before the

uninstallation can be imported for use.

(6) Application Program Settings

For the application programs that were using HDLM devices, specify the device file

of the Solaris

ssd

driver.
