Set up the root file system on the network

Copy the root file system to the NFS server and make some changes to adapt it to an individual BladeCenter^® server.

Perform the following steps to deploy your root file system on the NFS server:

On the POWER-based installation system, enable SSH logins by changing the entry SELINUX='enforcing' in /etc/selinux/config to SELINUX='permissive'.
Copy the root file system to the NFS directory by typing the following command on the NFS server:
```
# rsync -avp -e ssh -x root@<POWER-server>:/ /<NFS-dir>
```
where <NFS-dir> is the directory to which you want to copy the root file system. For example, enter:
```
# rsync -avp -e ssh -x root@192.0.2.20:/ /nfsroot/root_for_192.0.2.10
```
Make the following changes to the copy of the root file system on the NFS server.
- To make this image bootable, edit the /etc/fstab file and comment out the entries for "/", "/boot" and "swap". Failure to comment these out will cause errors on startup.
- Change the first line in /etc/fstab so that it specifies your NFS directory as the location of the root file system. For example, change line
```
/dev/VolGroup00/LogVol00 /                       ext3    defaults        1 1
```
  to read
```
192.0.2.22:/nfsroot/root_for_192.0.2.10 /        nfs     tcp,nolock      1 1
```
- Change the host name in /etc/hosts and /etc/sysconfig/network to the host name of your BladeCenter QS21.
- Remove the /dev/VolGroup00/LogVol01 swap line from /etc/fstab.

You now have a root file system in place for your BladeCenter QS21.

Tip: By copying this root file system to another directory on your NFS server you can easily create the root file system for further BladeCenter servers. After creating a copy you need to change the host name to that of the respective BladeCenter server.
