And also make sure that you have your SCSI chain terminated correctly. &nbsp;This will probably mean installing a terminator on your LTO if it is the last device in the chain. &nbsp;The article above explains your SCSI termination requirements.<br />

Thanks for your respond, on the back of my server I have two plugs one under each other , I guess I can plug two devices. and the symbol next to it is the last one in the link that you forwarded me , the LVD/SE.<br />
<br />
on the back of my new tape drive , it doesn't have a symbol , and the cable that came with doesn't have it also. but the connector on one end seems to be matching the one behind my server. My tape drive came with a termination plug. on the manual of the tape it says to plug the termination on the back of the tape drive ( there is 2 plugs on the back of the tape drive) . do I need to get another termination for the back of my server?, currently there is nothing connected on either one.

Yes you should terminate your server as well, however you may find that the server has smart termination, that being a built in terminator that disables itself if it detects that there is something else on the bus. &nbsp;You should read the manual for the server to determine this.<br />
<br />
Personally I ALWAYS use ACTIVE terminators on the end of my scsi chains and disable all other termination where possible.<br />
<br />
According to the manual <a href="http://support.dell.com/support/edocs/stor-sys/LTO2_024/en/ug/setup_ext.htm" rel="ugc">http://support.dell.com/support/edocs/stor-sys/LTO2_024/en/ug/setup_ext.htm</a>&nbsp;your tape drive is a Ultra160 LVD/SE device and you are required to install a terminator on the unused plug - meaning it does not have termination. &nbsp;Often device actuallyhave terminators on board which you can enable by setting a jumper, this would mean opening the box and finding the appropriate jumper to enable the onboard terminator.<br />
<br />
You will need to determine the need for a terminator on the other end of your SCSI Bus but I suspect it will not be needed.<br />

well, it didn't work . When I attached the drive and rebooted the servers. I got an error at the boot section. something like &quot;you cannot attached internal and external drives...&quot;<br />
I got also the message : 1776-SCSI bus<br />
<br />
annyway after removing the drive and rebooting the server, I got another message :<br />
1779-Slot 2 Drive array- replacement drive detected or previoiusly failed drives now appears operational. <br />
I was able to bring up my system, but for some reason I had an error that block all ethernet communication.<br />
&quot;The IPSec driver has entered block mode, Ipsec will be disabled.&quot; I disabled this service from starting up and everything came &nbsp;backnormal. <br />
Well, I think I am gonna buy a scsi adapter for my other server and plug it to a different server. I can't take the chance to break this server, it has my domain controller on it among other informations.<br />
<br />
I am not sure what really happened but it scared me a little ...<br />
Thanks,<br />

From:<br />
<br />
1776 &nbsp; &nbsp; &nbsp; Slot x Drive Array  SCSI Bus Termination Error  Internal and &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;external drives cannot both be attached to the same SCSI port. SCSI port &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;(y): Check cables (RESUME = F1 KEY)<br />
<br />
The internal and external connectors of the specified SCSI port(s) are &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;both attached to drives. The SCSI bus is not properly terminated when &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;internal and external drives are attached concurrently to the same SCSI &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;bus. The indicated SCSI bus is disabled until this problem is resolved. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Turn off the server power and check the cabling to the specified SCSI &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;port<br />
<br />
Looks like you did not manage to disable the termination on your internal card as per my previous post:<br />
<br />
You will need to determine the need for a terminator on the other end of your SCSI Bus but I suspect it will not be needed.<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ^^^^^^^^^^^^^^^^^^^^^^^^^^<wbr />^^^^^^^^^^<wbr />^^^<br />
<br />
I was wrong with my assumption it is needed... <br />
<br />
Your IPSec driver issue is completely independant of your SCSI issue. &nbsp;Had your computer rebooted you would of suffered the same problem.<br />
<br />
We need to get out the manual for your SCSI card and workout how to disable the internal terminators.<br />

Sorry for the late response.<br />
I actually ordered a SCSI card for my other server and plugged it there, I didn't want to mess with my production server and break something, i plugged my drive into the new Scsi and worked like a charm.<br />
Thanks for your help.<br />

Hi, <br />
I have a server HP Proliant ML370G3 and recently my backup tape drive Compaq Super DLT 110/220GB died. I am also out of warranty so I just purchased a Dell Powervault LTO-2-024 External Backup Drive. Now I am ready to connect it, but before I do that I just want to make sure that I won't have any coonflict with any hardware on my server.<br />
I have a SCSI Controller and a Smart Array 5300 Controller.<br />
1) what happens if I plug the drive and there is a conflict , could it cause big trouble.<br />
2) The scsi connector seems to be the match on the back of my server , There is no different configuration for the same scsi , right ? what I am trying to verify is that there is no different voltage base on the type of the version of the connector. I want to make sure that the the Tape Drive is compatible with my machine<br />
<br />
I hope it make senses<br />
<br />
Thanks<br />

how can I find the SCSI ID

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
