Hi Chris,
Are you sure a ChangerX device should support tape changers?
One of our customers successfully used \\.\ChangerX to share a CD/DVD-ROM changer device.

Any new information about tape changers? I have two HP Surestore 718 I would like to share as my backup server is a blade and there is not a way to install a scsi adapter.

Tape changers should work, you could try it wth the recent StarWind 3.0.
Please let us know if you need any help with StarWind.

Valery,
I'm using Starwing 3.0 Build 20060306
I cannot add the device \\.\ChangerX
I choose SPTI as device type and I receive the following error
Cannot add device.
Device test failed for '\\.\ChangerX'.
Here is a part of the log file.
4/5 10:49:17 c98 SPTI: '\\.\Changer5': sessions: 1.
4/5 10:49:17 c98 SPTI: '\\.\Changer5': Cannot open the device: The system cannot find the file specified. (code: 2).
4/5 10:49:17 c98 S: *ERROR* cannot open the device '\\.\Changer5'.
4/5 10:49:17 c98 Srv: * Device test failed for '\\.\Changer5'.
4/5 10:49:17 c98 conf: Device test failed for '\\.\Changer5'.
Any suggestions?
Thanks
Doug

Doug,
are you sure your changer device is '\\.\Changer5' ?
Have you tried '\\.\Changer0', 1, so on?
Also you could try to use 'Share R/W' option when creating the changer target.
Best regards,
Valeriy

I have tried \\.\Changer0 thru \\.\Changer5
all with the same results
I receive the same message using Share R/W option.
Any other thoughts?
Thanks

Are you sure your changer is mapped via "Changer" symbolic link? Did you try "Tape" as Valery suggested already?

Anton,
I have \\.\Tape0 and \\.\Tape1 mapped already and they work fine. Actually they showed up in the list, should I remove these and then try the changer symbolic link?
I need is to be able to use the changers along with the tape drives.
These is one tape drive in each HP Tape Changer.
Hope this helps.
Doug

Unfortunately it does not... We need to know device name before we'll share it. For now please try to bug HP support with it (there should be GUID-like one and human-readable one, we need second one) and we'll try to write down additional utility to enumerate device names by class.

Doug,
Are the changer devices recognized by the local system and visible in the Device Manager?
Also it's possible that they use their own proprietary interface, not supported by Windows directly.
What is the software that works with the changers?
Best regards,
Valeriy

The changers are recognizes by Windows Server 2003.
They are connected to an Adaptec 29160 SCSI Controller.
They show up under the Medium Changers category in Device manager. They are listed as HP Tape Library.
Microsoft backup can use them, or I can install any backup software that supports tape libararies and use them.
I am checking with HP to see if I can get any more info.
Thanks
Doug

No luck finding anything from HP, but I did learn that it is the O/S that assigns the scsi device names.
So now I just need to find out how Windows server 2003 names it's devices.
