GPFS: 6027-572 Completed creation of file system /dev/gpfs0fs.

This is an asynchronous process.

5.6.3 Adding a node

To add a node to the RSCT peer domain and the GPFS cluster, complete the

following steps:

1. Prepare the security environment on the node you want to add to the peer

domain. The node from which you issue the

addrpnode command is called the

originator node.

preprpnode originator_node

2. Add the node to the peer domain on the originator node:

addrpnode node_name

Example 5-8 shows the lsrpnode command output after adding the node.

Example 5-8 lsrpnode command output

sp4n33e0 Online 2.2.1.20

sp4n01e0 Online 2.2.1.20

sp4n05e0 Offline 2.2.1.20

sp4n17e0 Online 2.2.1.20

3. Bring the offline node online from any node in the current peer domain:

startrpnode node_name

or

startrpdomain domain_name

4. Add the node to the GPFS cluster. The mmaddcluster command allows the

node to import the existing VGs information at this time.

mmaddcluster node_name

Note: If the configuration resource manager (ConfigRM) is not running

correctly on each node of the peer domain, you cannot add the node to the

peer domain.
