shorty,
This looks like a solaris box. If its is, its is most likly c1t2d0s0. It will depend on how to formatted the disk. If you are on a sun box. Use format command to look at how it is name. Using format will not change anything IF

you just use it to look at the disks. Please do man on format command before using it. I think if you use df -k it should also give you disk naming.
