problem with backup exec 10d not seeing pv124t with new 160 scsi card

Are the devices seen in the Scsi controller bios?

What OS are you running?

If Windows 2008

NOTE: The PV124 VS160 has a known issue with Windows 2008 OS when connected to a controller card using StorPort drivers. The medium changer will not be seen in device manager, therefore the robot is not properly discovered or displayed. Therefore, this is an unsupported configuration, but as a workaround SCSIPort drivers may be used The user may also manually move media into the drive via the PV124T Remote Management Unit or Operator Control Panel, or connect the PV124T to a Windows 2003 Server. This is documented in Microsoft knowledge base article: http://support.microsoft.com/kb/967736.

yes it is seen on the scsi contrller bios. I'm running windows 2003 server.

So device manager sees the drive and medium changer?
only backup exec does not. you may need to run the diver pack again (tapeinst.exe)

you will need your version of 10d service pack.

I ran the driver pack again and reboot still didn't show up. Someone recommended shutting off the autoloader for at least 20 seconds then reboot the server and somehow this did the trick. The backup exec now recognizes the drive and slots and we're back in business.

Thank you very much for taking the time to help me on this issue.
