While using DAT USB drive-the tape ejects on reboot
We are seeing few instances of the above. We tested this with USB DAT 40 and 72. We have tested with 2000 and XP and same results. Has anyone seen similar problems?
This is a major problem if it is a remote site. The customer wouldnt want the tape to eject each time they reboot the server.

Re: While using DAT USB drive-the tape ejects on reboot
Note that most tape drives will rewind or rewind and eject on bus reset.
Good luck,
Vince

Re: While using DAT USB drive-the tape ejects on reboot
Thanks for the info.
But the device here is USB and not SCSI.

Re: While using DAT USB drive-the tape ejects on reboot
However, I would expect a tape drive to act like a tape drive - both SCSI and FC drives react badly to bus resets.
However, I did find this:
Microsoft supplies a USB Mass Storage driver called USBSTOR.sys, this has some limitations for tape device use, so it is recommended that an HP replacement driver is used called HPUSBMSC.sys.
The HP USB Mass Storage driver is installed by running a driver installer supplied on CD with StorageWorks drives and is also available on the Support Web site.
I would start with that, if you haven't done so already.
Personally, I would not suggest the use of a USB DAT drive for backup in a remote site. A 1/16 Autoloader is much more easily remotely administered and reliable. The fact that it has multiple tapes in it and the software changes them for you removes the problem of the Secretary or whoever you've got changing the tapes not changing the tapes or cleaning the drive, etc.
I've seen many remote sites lose all their data because their backups were on tapes that had been written to hundreds of times. They wear out... in less than a year if you don't change it. You might be surprised how often this happens and how few people think about tape wear.
Regardless, good luck with the drive. Try the support line if the driver changes (if any) don't solve your problem or nobody else here suggests something.

Re: While using DAT USB drive-the tape ejects on reboot
Vincent is correct. You must use the USB drivers that come with the tape drive. If they are not used Windows will not be able to communicate with the tape drive.
Once you have the right drivers loaded you can then look at the firmware of the drive using Library and Tape Tools.
You can download Library and Tape Tools from http://www.hp.com/support/lttdownload

That is not correct. From the users guide:
"hp_usbstor: This is a USB Storage device used by hpdat and it replaces the Microsoft usbstor driver for HP USB tape drives. The HP StorageWorks USB DAT drives will work with the Microsoft usbstor driver, however, HP strongly recommends the use of the hp_usbstor driver as it offers improved functionality"
Murthy,
The HP product engineering team attempted to duplicate your tape eject problem. They reported: "We power cycled with the drum spinning, with the drum stopped etc, and the power cycle itself is not able to cause the tape to eject. We can therefore only suggest that it is something in the specific boot up procedure that causes this to happen."
There testing was done with the HP drivers.
Can you confirm if the problem occurs even with the HP tape AND USB storage drivers installed?
Any additional details you can provide (such as backup application installed, RSM enabled, etc) may help. Also, collecting an L&TT support ticket immediately after the tape eject (once the server is running) may show something in the device logs. Have you also looked in the Windows system event log for any indications of a possible problem?

Re: While using DAT USB drive-the tape ejects on reboot
Thanks for the clarification on that. I will note that down in our USB info page.

Re: While using DAT USB drive-the tape ejects on reboot
It was a minor point, although important to note that just because the device is communicating to the OS doesn't mean that it has the HP USB and DAT drivers installed. HP's solutions testing is based on the HP drivers, so that is what we strongly encourage folks to use.
It will be interesting to find out of the eject behavior here is related to the use of the MS USB storage driver.

Re: While using DAT USB drive-the tape ejects on reboot
FYI, if you are using backup exec, it requires the latest HP DDS driver (1.5.3.1). From the Veritas website on the DAT 40/72 USB: "The Hewlett Packard HPDAT.SYS driver v1.5.3.1 (or higher) is required for use with Backup Exec for Windows Servers."

Re: While using DAT USB drive-the tape ejects on reboot
I tried with HP USB driver HPUSBMSC.SYS and this is when the problem occurs. I replaced this driver with USBstor.sys and we did not see the problem (this is in my test environment)
With the HP driver, I did not have problem backing up or restoring (but the eject problem was there).
With the USBSTOR.SYS, the Eject problem was not seen (though I had problem while trying to restore after a successful backup. But this could be some silly configuration problem which I will try to isolate)
One more strange problem I noticed when the USB DAT 72 external drive was connected to a DL380G3 Windows 2000 Advanced server was that the OS did not load. Received error "Attempting to boot from CD rom" and just hung for ever. This happend each time after reboot whether the USB drive was on or off.
I had to change the boot order to HDD->CD rom->FDD....(there is no USB option)
Regds,
