5.
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
6.
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
sd
or
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
sd
or
ssd
driver.
