Building an HA Cluster Configuration

Preparing Your Systems

Chapter 5 217

Use the command insf -e on each node. This will create device files

corresponding to the three partitions, though the names themselves may

differ from node to node depending on each node’s I/O configuration.

Step 5. Define the lock LUN; see “Defining the Lock LUN”.

Defining the Lock LUN

Use cmquerycl -L to create a cluster configuration file that defines the

lock LUN.

• If the pathname for the lock LUN is the same on all nodes, use a

command such as:

cmquerycl -C $SGCONF/config.ascii -L /dev/dsk/c0t1d1 -n

• If the pathname for the lock LUN is different on some nodes, you

must specify the path on each node; for example (all on one line):

cmquerycl -C $SGCONF/config.ascii -n <node1> -L

/dev/dsk/c0t1d1 -n <node2> -L /dev/dsk/c0t1d2

These commands create a configuration file which you can apply to the

cluster configuration when you are ready to do so; see “Distributing the

Binary Configuration File” on page 242. See also “Specifying a Lock

LUN” on page 237.

CAUTION Once you have specified the lock LUN in the cluster configuration file,

running cmapplyconf will destroy any data on the LUN.

Setting up the Quorum Server

The quorum server software, which has to be running during cluster

configuration, must be installed on a system other than the nodes on

which your cluster will be running. For more information and

recommendations, see “Using a Quorum Server” on page 145.

Use the HP-UX swinstall command to install the quorum server,

product number B8467BA, on the system or systems where it will be

running. More details on installation are in the Quorum Server Release

Notes for your version of Quorum Server.
