Removing SCSI Hardware Entries

I am looking for a way to remove old SCSI hardware that is reporting in the
SCSI devices in the registry.

Situation:
After replacing a "PLASMON FTA" tape library, the new unit came wiht an
Identity String of "EXABYTE 110L". Windows detected and created the strings
in the SCSI devices with no problems, but after correcting the Identity
String to "PLASMON FTA" Windows 2000 Server hangs during the boot process
until I either power fail the unti, or perform a soft reset of the unit.

My goal is to remove the settings in the registry so that windows knows
nothing about the old or the new Library and allow the SCSI device to be
redetected.

I tried to delete the registry entries for the devices, and windows will not
allow me.

So my question is how do I get rid of the old SCSI devices, because I
suspect that there is a windows conflict in what it sees during the boot, 2
devices identicle but with different strings and windows does not know which
one to load.

Additionally, where can I log the boot process to see exactly what is going
on behind the scenes? And trace any issues that might be happening.

Thanks
J
 
1.) To display hidden devices, non-Plug and Play devices, and devices not
attached to the computer (commonly known as "ghosted" or "phantom" devices)
Save the following two lines as a file then execute.

--------------------------setdev.bat---------------------
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc
---------------------------------------------------------

Then, View|Show Hidden Devices to remove or reconfigure these devices. Do
not edit the registry.


2.) Try F8 at startup and 'Enable Boot Logging' then look for 'ntbtlog.txt'
in the %windir% directory.

Great information!

I believe delete the hidden device will resolve this issue. In addition,
you may also check the following regsitry key:

HKEY_LOCAL_MACHINE\Hardware\Devicemap\Scsi\ScsiPortx\ScsiBusx\
TargetIdx\LogicalUnitIdx

I suggest you backup this registry and delete the corresponding keys,
restart the machine to allow it automatically detect the SCSI drive. I
would like to list the following articles for your reference:

How to troubleshoot error messages about Event ID 9 and Event ID 11
http://support.microsoft.com/?kbid=314093

Hope it helps.

Any udpate, let us get in touch!

Hi Guys,
Excellent info...I was able to run the commands as you outlined, and removed
the phantom devices that were listed, and corresponded to the registry
entries that I found.

However, my problem did not go away. The server still hung during the boot
process, so I flip flopped the devices attached to the two channels, and the
problem moved to the other device. I suspect at this point I have a SCSI
card issue that has been masking my Backup Software issues...just not sure
why all of a sudden for a windows boot that the issue started.

Thanks guys
J
 
According to your description, I believe this is the SCSI card issue. It is
possible that the card corrupted and Windows cannot recongnize it.

Please contact the SCSI manufacturer to change card to test this issue.

Good luck!

Thanks again.
Changed the card, still the same results. Received a new unit, same results.
Finally what I noticed in the hardware config of the Tape Drive, was that
there was no BarCode Reader Installed. The original hardware had a bar code
reader for LTO tapes, the BrightStore software supports a bar code, and
allows for quicker inverntory of daily tapes. But with out a bar code reader
installed in the unit, the software times-out, and dismounts the slots in the
library.

The manufacturer sent a reader, installed it, and problem solved. Who knew!

Thanks for the Device Manager tips though, I will be adding this to my bag
of tricks.

|I am looking for a way to remove old SCSI hardware that is reporting

in
the
| SCSI devices in the registry.
|
| Situation:
| After replacing a "PLASMON FTA" tape library, the new unit came wiht an
| Identity String of "EXABYTE 110L". Windows detected and created the
strings
| in the SCSI devices with no problems, but after correcting the Identity
| String to "PLASMON FTA" Windows 2000 Server hangs during the boot process
| until I either power fail the unti, or perform a soft reset of the unit.
|
| My goal is to remove the settings in the registry so that windows knows
| nothing about the old or the new Library and allow the SCSI device

to
be
| redetected.
|
| I tried to delete the registry entries for the devices, and windows will
not
| allow me.
|
| So my question is how do I get rid of the old SCSI devices, because I
| suspect that there is a windows conflict in what it sees during the boot,
2
| devices identicle but with different strings and windows does not know
which
| one to load.
|
| Additionally, where can I log the boot process to see exactly what is
going
| on behind the scenes? And trace any issues that might be happening.
|
| Thanks
