TL891

1. Drivers are always lost when I reboot my server, hence, I have to do the job again and again.

2. Removeable Storage can find tape drive only. Library never shows up in the category. Never detected successfully in "Removable Storage".

3. Drivers change when I click "scan for new hardware".
For example, when I update library driver from "Unkonw medium changer" to " "HP StorageWorks DLT TL Series Medium Changer", the library might be disappeared. Then when I click scan again, it becomes "Unkonw medium changer" or "HP StorageWorks DLT TL Series Medium Changer".

I've been working on this for two week but still cannot solve it. Is there anyone can tell me where I did wrong? Thank you so much.........

Below is my test result.

BIOS can detect both library & tape drive when booting.
Ch B, SCSI ID: 1 DEC TL800
SCSI ID: 5 DEC DLT8000

Results of LTT:
Sometimes only DLT Tape drive can be found, sometimes both library & drives, and sometimes none. But it can never detect library correctly.

Found 'DAC TL800 (C)@EC' at address 5/0.1.0
Device is not claimed by NT
Unexpected Win32 error encountered during I/O scanning: 1
Found 'DLT8000 at address 5/0.5.0
Device is claimed by NT: class driver is \.\Tape0


Windows Device Manager:
Case 1:
Both library & tape drive can be found.
Case 2:
Only tape drive can be found.
Case 3:
None could be found.

Re: TL891

Hi,

Is this a TL891 or a TL891DLX ??

If the former, then it will be a Differential (HVD) SCSI device, which will need to be connected to a Differential SCSI card...

Hope this helps,

Regards,

Re: TL891

Sound like a windowz plug&play problem, this may occurs when the system is not working well and it discover a lot of new devices. these devices (always the same) are listed under hidden devices and in the registry, I have seen this causing similar problems.
solution is to ask windows support to have a look and remove old hidden devices from the device list
