Backup exec 10 - not detecting our tape

We have a Dell Powervault 114 t (LTO Ultrium 3 tape) which performs our nightly backup.

Since last Friday however, the backups have failed since Symantec backup exec says that the job is "Ready; no idle devices are available"

Yesterday, I rebooted both the server (that has the backup exec software installed)  and the Dell Powervault.

Still the same thing.

Today, I have disabled and deleted the Dell device on the Devices - tab in Backup exec.

What now ?
I can't add the Dell device any longer in Backup exec, it's not showing up ...

Check the SCSI cables and also the terminators. Replace the cables if necessary. Does the system "see" the connected drive while booting?

I checked the cables and they seem OK.

I can't restart the server during business hours, since it's also performing other tasks. If that's necessary, then I will do it tonight.
I'd still change the cables, often there is nothing visibly wrong.

Are you able to see the device using Windows Backup? Is it in Device Manager? You may just have to reinstall the Veritas drivers for the device (or not use them at all).
As rindi stated confirm that the device is being seen by the SCSI controller at boot. If not then thats either termination, cable, SCSI Controller or system board issue.

As victornegri stated make sure to use the correct Backup Exec Drivers.

I would do the following during non-production hours.

Turn off both the Server and PowerVault
Confirm there are no bent pins on the cables
Confirm correct termination
Turn on the PowerVault
Make sure the device is seen during boot
If it comes up and can been seen by Windows Device manager confirm that the drivers are signed by Symantec not Microsoft
If they can't been seen or are signed incorrectly remove the devices from device manager.
Download the newest Driver Package from Symantec and Install them
Reboot the Server again and bring it back up.
From the Backup Exec Admin console run the Wizard and reconfigure the device(s)

That's a start.

Turning the Powervault off didn't make it show up again. However, unplugging it from the power outlet for about 6 seconds, and then plugging it back in made it pop up again in the device manager!
