Symantec 5 manual Setting up a node to join the single-node cluster

144Installing VCS on a single node

Adding a node to a single-node cluster

Setting up a node to join the single-node cluster

The new node to join the existing single node running VCS must run the same version of operating system and patch level.

To set up a node to join the single-node cluster

1Do one of the following tasks:

■If VCS is not currently running on Node B, proceed to step 2.

■If the node you plan to add as Node B is currently part of an existing cluster, remove the node from the cluster. After you remove the node from the cluster, remove the VCS RPMs and configuration files.

See “Removing a node from a cluster” on page 131.

■If the node you plan to add as Node B is also currently a single VCS node, uninstall VCS.

See “Uninstalling VCS 5.0 RU3” on page 154.

■If you renamed the LLT and GAB startup files, remove them. See “Renaming the LLT and GAB startup files” on page 142.

2If necessary, install VxVM and VxFS.

See “Installing VxVM or VxFS if necessary” on page 144.

Installing VxVM or VxFS if necessary

If you have either VxVM or VXFS with the cluster option installed on the existing node, install the same version on the new node.

Refer to the appropriate documentation for VxVM and VxFS to verify the versions of the installed products. Make sure the same version runs on all nodes where you want to use shared storage.

Installing and configuring Ethernet cards for private network

Both nodes require Ethernet cards (NICs) that enable the private network. If both Node A and Node B have Ethernet cards installed, you can ignore this step.

For high availability, use two separate NICs on each node. The two NICs provide redundancy for heartbeating.

See “Setting up the private network” on page 40.
