I just caught this thread and was wondering what type of tape drive you're trying to use?
I went through evaluating Linux as a potential replacement for one of our backup servers (very old SGI Challenge DM) and tested the following drives: DLT4000 (in a stacker) LTO (IBM and Seagate) DTF-2 (SCSI) The only drive I had problems with was the DLT4000 and I got messages similar to the ones you described below. In some cases I could tar to the tape drive, but not restore, etc.. Going through the compatibility lists for Legato Networker and Veritas Netbackup (we run Veritas) I saw that neither of them supported DLT4000's on Linux. I haven't had an opportunity to try DLT7K's or DLT8K's yet. -Steve -----Original Message----- From: Ed Cooley [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 28, 2003 12:05 PM To: [EMAIL PROTECTED] Subject: RE: Tape drive problem on Dell 4600 We have replaced the drive with a new one and the results are the same. If it was the tape drive, why would linux hang on os install?

This honestly looks like a tape drive issue. If you have an identical one, try swapping them. See if the problem follows the drive. I know it may not be feasible but worth a try if possible. <<JAV>> ---------- Original Message ----------- From: "Ed Cooley" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Mon, 27 Jan 2003 14:09:41 -0600 Subject: Tape drive problem on Dell 4600 > I am having a strange SCSI tape drive problem on a Dell 4600 server > with an internal Benchmark DLT Drive OEM from Dell. > > We backup about 30-40 Gigs of data each night.
