Renaming Sun Cluster node names

Sometimes a hostname need to be changed especially when your customer wants to make the server names more orderly to correctly identify your machine or applications.

Make a copy of /etc/cluster/ccr/infrastructure file

Edit /etc/cluster/ccr/infrastructure file and change the node names as required, For example

Before:

cluster.nodes.1.name    OLDSVR1
cluster.nodes.2.name    OLDSVR2

After:

cluster.nodes.1.name    NEWSVR1
cluster.nodes.2.name    NEWSVR2

(optional) Change the Solaris node names in /etc/hosts and /etc/nodename to match the new server names (see this post for additional files to edit)
Regenerate the checksum for the infrastructure file:
```
# ccradm -i /etc/cluster/ccr/infrastructore -o
```
(optional) If running VxVM, change the global-id for VxVM as well (adds the new hostid to /etc/vx/volboot file)
```
# vxdctl hostid NEWSVR1
```
Shutdown the cluster
```
# cluster shutdown -g 0 -y
```
Boot both nodes with the new values
```
ok boot
```

Note: This procedure can be run with the cluster online but you will need to shutdown and reboot the cluster to make changes effective
