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
1
Do 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.

If necessary, install VxVM and VxFS.
See “Installing VxVM or VxFS if necessary” on page 144.
Installing VxVM or VxFS if necessary
If you have eitherVxVM or VXFS with the clusteroption installedon the existing
node, install the same version on the new node.
Referto theappropriate documentationfor VxVM andVxFS toverify theversions
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 requireEthernet cards(NICs) that enable the privatenetwork. Ifboth
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.
