Adding and removing cluster nodes

129

Adding a node to a cluster

 

If the file on one of the existing nodes resembles:

0galaxy

1 nebula

Update the file for all nodes, including the new one, resembling:

0galaxy

1nebula

2 saturn

2Create the file /etc/llttab on the new node, making sure that line beginning "set-node" specifies the new node.

The file /etc/llttab on an existing node can serve as a guide.

The following example describes a system where node saturn is the new node on cluster number 2:

set-node saturn set-cluster 2

link eth1 eth1 - ether - - link eth2 eth2 - ether - -

3On the new system, run the command:

# /sbin/lltconfig -c

To configure GAB

1Create the file /etc/gabtab on the new system.

If the /etc/gabtab file on the existing nodes resembles:

/sbin/gabconfig -c

The file on the new node should be the same. Symantec recommends that you use the -c-nNoption, where N is the number of cluster nodes.

If the /etc/gabtab file on the existing nodes resembles:

/sbin/gabconfig -c -n2

The file on all nodes, including the new node, should change to reflect the change in the number of cluster nodes. For example, the new file on each node should resemble:

/sbin/gabconfig -c -n3
