DL380G2 / AIT 50 Tape Problem

[John P. O'Banion]

I have been using a Compaq Hot-Plug DAT 20/40 in Slot 5 of my DL380G2 with a 5302-128 controller for several years without a problem. The other day, I decided to upgrade to a Compaq Hot-Plug AIT 50.

The drive is recognized by Windows 2000 and shows up in removable storage. StorageWorks Tape Tools sees the drive without any errors (as an SDX-500C).

However, neither NTBackup nor Veritas BackupExec 8.6 will work. I get errors indicating timeout problems or unknown functions being executed. In event viewer, there are cpqcissm errors indicating controller driver erros at \device\tape0\cpqcissm2.

The firmware on the drive is 1.38; the drivers are up-to-date, and the firmware and drivers for the 5302 are up-to-date.

Yet, the device is not working. I'm about to put the DAT 20/40 back in the server.

Help, please. Thanks.

1. If you using Veritas BackupExec 8.6 try to disable Removable Storage Service.
2. Manualy uninstall and reinstall Tape Drive in Device Manager, and manualy put the newest drivers for Tape drive.

Hi, try update the firmware, most problems are solved by using a new firmware release

you can also do some diagnostic testing.

Thanks. I updated to the latest firmware for the drive and the controller, and have the latest drivers as well.

I am not able to get L&TT to work either. The error messages are "the semaphore timeout period has expired" followed by "I/O bus reset".

John,

Try the HP native driver kit. This supports the AIT50 and AIT100 units and may help resolve your issue.

I hope this helps.

Thanks Brian,

I did try the native driver kit as suggested (the driver is old, but recognized). Still no dice. The drive just won't read or write without errors. I was convinced it was a driver problem, but now I'm not so certain. L&TT won't work with the driver either, and I spoke with HP/Compaq who said that L&TT has its own drivers.

I'm thinking maybe a bad drive? Bad tape?

Has anyone ever got this to work?
