Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

■ Hardware and software requirements are met.
See “Meeting hardware and software requirements” on page 278.
■ Hardware is set up for the new node.
See “Setting up the hardware” on page 278.
■ The existing cluster is an SFCFS cluster and that SFCFS is running on the
cluster.
■ The new system has the same identical operating system versions and patch
levels as that of the existing cluster.
Meeting hardware and software requirements
The system you add to the cluster must meet the hardware and software
requirements.
See “Assessing system preparedness” on page 30.
If the cluster is upgraded from the previous SFCFS version, you must check the
cluster protocol version to make sure it has the same version as the node to be
added. If there is a protocol mismatch, the node is unable to join the existing
cluster.
To verify there is no protocol version mismatch between the cluster and the new
node
◆
Check the cluster protocal version using:
# vxdctl list |grep protocol
On the master node, check the upgrade protocol using:
# vxdctl upgrade
Setting up the hardware
Figure 18-1 shows that before you configure a new system on an existing cluster,
you must physically add the system to the cluster.
