I have Server Dell 4400 power edge OS: NT 4 Server with Service Pack 6
Tape Drive: Compaq DLT7000 External
Backup Software: Arc Serve 2000

When I take the backup, it starts successfully and after finishing the
First tape it asks for the second tape to continue, when we insert second
Tape. After a while, it gives me hardware error. And fails the backup. I
Have following different error numbers.

E6300 WIN NT SCSI Port Error

Hi:

I know nothing about tape back-ups, or Arc Serve, but I did a search on Google and found the following discussions of problems, similar to yours.

[list]ARC Serve document (http://www.ocss-va.org/services/technology/helpdocs/ARCserve.doc[url)
Tek Tips - Arc Serve discussion (http://www.tek-tips.com/gviewthread.cfm/lev2/7/lev3/49/pid/478/qid/414054[url)
Computer Associates-Technical Support (http://support.ca.com/[url) (they manufacture ARC Serve)

Hopefully, this will be of some help.
