Infrastructure Software

I need to replace a hard drive on a Sun Fire X2200. It is giving a bad sector error. The problem is I do not know what is the best method to replace the hard drive. Our UNIX admin had a stroke so I am left to take over the administration until he is back. There are two hard drives that are in the server. I have never replaced a hard drive in a UNIX system. I usually use ghost to backup Windows machines. Below are some commands I ran to gather some information. For some reason I cannot run the format command right now. I will have to try it at the console tomorrow. The hard drive that needs replaced is c2d0. I am not sure if I need to copy the data to another hard drive or restore it from a backup? Do I need to boot into single user mode to do the backup and restore? The system is being backed up using Legato Networker on a regular basis, but I have never used the software until now. I have been just changing the tapes out. Also, I ordered an identical server so I can do some testing on it. Thanks in advance.
