Veritas Backup Exec Win 2000 + Compaq DDS-3 DAT drive job failures 1

[jedenigma]

Home office: Pentium II 400 Server, self-built, PC-class, but commercial quality components and properly configured.

Windows 2000 Server (SP2)
Microsoft Exchange Server 5.5 SP3
384 Mb RAM
3x60Gb Ultra ATA-100 7200 RPM on Ultra100 Controller (Abit)
WinNT/2000 OS Managed RAID-5 Array (120 Gb Total Space)
Compaq 12/24 Gb DDS-3 DAT (SDT-9000 4mm)
Compaq 32-bit PCI SCSI Controller (Symbios based)
Veritas Backup 8.0 build 3316
The firmware on the DAT drive is 4.05.

I purchased the DAT drive new, via my company. I installed the drive in the server and it worked fine with Windows 2000 NTBACKUP. I used it in this configuration for about a month and had no problems.

It became necessary to schedule backups, so I installed Veritas Backup Exec v8.0 build 3316 and Veritas' Microsoft Exchange Server Option. Since installing Veritas Backup Exec the system will not backup successfully. It backs up about 1.4 Gig and then stops with an error message. In the the job log the process ends abruptly with this message:

Storage device "COMPAQ 1" reported an error on a request to write data to media.

Error reported: The request could not be performed because of an I/O device error.

Any input would be greatly appreciated. I have tried using Microsoft vs. Compaq DAT drive driver, as well as alternating between Microsoft and Compaq SCSI Controller drivers. No luck.

Thanks much

Justin

Here is a paste of the message that appears during backup.


Storage device "COMPAQ 1" reported an error on a request to write data to media.

Error reported:
The request could not be performed because of an I/O device error.

Need help! I us back Exec on my Network. I have Backup Exec installed for server1 which is my backup Server. I select the back up Server to be backup and I have 3 other servers on my network that I select in my entire Network and it bring up my network and I select the other servers but I did not select the server1 on the Network. I Only selected Server1 when it displayed it as the backup Server. I select the other servers for back and Backup Exec will backup my other server but it will not backup Server1 were Backup Exec is installed and were I do my configuration. Do I have to select Server1 when I select the other servers on the Network.

I got mine working finally, the problem was related to tape drive device drivers.

Initially the system recognized the hardware and used Microsoft Windows 2000 drivers for the SCSI controller and the DAT drive. When Backup Exec was installed it replaced the Microsoft tape device driver with a Veritas tape device driver.

I had to remove all device drivers that were installed by Microsoft AND by Veritas. I used the COMPAQ drivers for the SCSI adapter AND the DAT drive.

It works like a champ now and backs up at over 100 Mb/min.

Good Luck!
