Managing HP Serviceguard for Linux, Eighth Edition, March 2008

Building an HA Cluster Configuration
Preparing Your Systems
Chapter 5 157
NOTE Follow these rules:
• Do not try to use LVM to configure the lock LUN.
• The partition type must be 83.
• Do not create any filesystem on the partition used for the lock LUN.
• Do not use md to configure multiple paths to the lock LUN.
To transfer the disk partition format to other nodes in the cluster use the
command:
sfdisk -R <device>
where <device> corresponds to the same physical device as on the first
node. For example, if /dev/sdc is the device name on the other nodes use
the command:
sfdisk -R /dev/sdc
You can check the partition table by using the command:
fdisk -l /dev/sdc
NOTE fdisk may not be available for SUSE on all platforms. In this case, using
YAST2 to set up the partitions is acceptable.
Setting Up and Running the Quorum Server
If you will be using a quorum server rather than a lock LUN, the
Quorum Server software must be installed on a system other than the
nodes on which your cluster will be running, and must be running during
cluster configuration.
For detailed discussion, recommendations, and instructions for
installing, updating, configuring, and running the Quorum Server, see
the HP Serviceguard Quorum Server Version A.03.00 Release Notes at
http://www.docs.hp.com -> High Availability -> Quorum Server.
