Disk /dev/cciss/c0d0: 26.2 GB, 26212270080 bytes
255 heads, 63 sectors/track, 3186 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p2 2040 3186 9213277+ 82 Linux swap

Disk /dev/cciss/c0d1: 26.2 GB, 26212270080 bytes

c0d0 = disk 0
c0d0p1 = disk 0 partition 1 ... and so on


Is this an HP HW box ?
Show output of
Code:
df -h

cat /etc/fstab

cat /etc/*release*
To create 500 users in a batch, you could roll your own method, but you may want to base it on http://linux.die.net/man/8/newusers


As you are new to Linux, I recommend

Welcome to LQ

BTW RHEL4 went out of regular support in February; you should get latest 5.x or 6.x
http://www.redhat.com/security/updates/errata/

If you don't want to pay for updates & support, go with Centos https://www.centos.org/: a free rebuild of RHEL, inc updates but not support.

I suppose you mean that you want all home directories for the users to be on /dev/cciss/c0d2p1. For this to be possible, /dev/cciss/c0d2p1 needs to be mounted somewhere in the filesystem hierarchy. The obvious choice would be to mount it on /home, but you can mount it anywhere.

chrism01 asked for the output of df -h so we can see if /dev/cciss/c0d2p1 is mounted and where.

During the process of the creation of users, you can specify their home directories and you can simply use 'path_to_mountpoint/userA', 'path_to_mountpoint/userB' etc.

In a standard setup, path_to_mountpoint will translate to /home, but if you mount your disk on a (newly created) directory /extradisk, it will translate to /extradisk
