Problem HP DAT 72 internal USB not detected on Proliant ML150 G3 (WIN Server 2003 R2)

[JJ Martin]

Hi,

I am experiencing problems with a HP StorageWorks DAT 72 internal USB tape drive (AE307AT) :

The HP DAT 72 is firstly detected when plugging USB on a new Proliant ML150 G3 (Windows Server 2003 R2).
Then after a few backups, it is not detected anymore : LTT doesn’t recognize hardware anymore, neither Windows device manager.

We have changed the tape drive 2 times and also HP cartridges: it’s the same, firstly detected then not, after a few backups. All firmware and drivers are updated with the most recent from HP. No problem with others USB devices. Rq: HP Data Protector Errors : first 1400 & 1401 (“Insert compatible media”) and then “Tape drive not detected”.

Thanks for your help.

Has the tape drive's USB cable been inserted into more than one USB port on the server?

USB problems are often caused by randomly inserting them into different USB ports.

Use the following Microsoft KB article to clean out the 'phantom' devices:

Thank you Kedd for your help.
Excuse my bad english.

Yes, the tape drive's USB cable has been inserted into more than one USB port on the server (internal and external) : but every time it's the same thing : firstly recognised in L&TT and in Device Manager, then not recognised in L&TT and error in Device Manager.

The most recent Windows driver (provided by HP) has been installed and re-installed : always the same.

We can see the device in Windows Device manager (error), so it seems not to be a problem of Phantom device...

Any other available Windows driver for this tape drive HP StorageWorks DAT 72 USB (AE307AT) for Windows Server 2003 R2 ?

Thanks for your help.

There is one more thing you may want to check in Device Manager -> Universal Serial Bus Controllers. In the properties of each USB Root Hub -> Power Management tab -> uncheck Allow The Computer To Turn Off This Device To Save Power.

It looks like a new version of L&TT and its configuration utility was release just a few days ago:

Thanks Kedd for your help.

I have unchecked "Allow The Computer To Turn Off This Device To Save Power" on every USB Root Hub.

Last version of L&TT (v.4.2) and utilities was installed (Tape drive not detected).

In device Manager : "HP USB Mass Storage Device" was still in error ("This device cannot start - code 10"). Trying to reinstall Windows driver (the last one on hp.com) does not change anything ("last driver already installed").

When changing USB Port, device is reinstalled, but now in device manager it's "Unknown device". Trying again to remove and reinstall Windows driver does not change anything.

It's the same when Rebooting the server.

The Windows Server 2003 driver provided by HP seems not to be compatible with Proliant ML 150...

Any suggestions ?

Thanks for your help.

What version of Support pack?
Bios and firmwares ?

[Kedd Guyton]

You mentioned changing out both the tape drive and the cartridges. Have you tried another known working USB 2.0 cable?

Is the tape drive on a UPS?

Hi,
I've changed USB cable : always the same.
Tape drive not on a UPS.
Last drivers, Bios and Firmware from HP updated.
Thanks for your help.

It sounds like you've swapped everything but the server's system board.
