Capacity showing incorrect in Backup Exec LTO2

Posted on 2004-11-17

Hi All,

We have just purchased a DELL Powervault 110T LTO-2 Tape drive and upgraded to Backup Exec 9.1 for Small Business Server 2003.

Everything seems to have installed ok, i can see the tape device, and backup exec seems to be functioning correctly.  However the media is reporting an incorrect capacity.  If i double click one of the media to view the properties it shows the capacity as 17gb which is incorrect as the tape media is 200gb/400gb.  Because of this, everytime i attempt a test run on the backup it fails with a message indicating insuffuicient capacity, or free capacity check failed.

Has anyon had anything similar, or has any suggestions.

Thanks in advance

    Have you downloaded and installed the patches and fixes for backup exec 9.1 from Veritas? Probably what you need are the device and media support patches. Are you using the drivers supplied by windows  or those  of backup exec (always assuming you are using a Windows Server...

    I have installed the Service Pack 1 for Backup exec 9.1. It is a windows 2003 server, SBS.

    I think we are using the drivers installed with windows.  I basically installed the tape drive, installed drivers etc in windows, then installed backup exec 9.1, then downloaded Service Pack 1 and installed it.

    How can i check whether its using windows drivers or Backup Exec drivers?

    It's pretty poor at telling what the capacity of the tape is, gets quite a few wrong. Just disable capacity checking,

    If veritas installed drivers during the installation process, you are most likely to be using the veritas drivers.

    You will probably need to reinstall the tape drivers and use the Veritas drivers, not the windows ones.  When I upgraded to 9.1 from 8.6, it installed the Windows drivers for some reason and I was getting lots of tape drive errors.
