Dell Powervault TL2000 iSCSI Bridge - LAN Scan to find IP?

Question

I have a Dell TL2000 with a F092G iSCSI Bridge that I just installed. The iSCSI bridge was purchased used and attempts to access the management web page at the default 10.10.10.10 address have failed (changing my local IP to 10.10.10.11 per instructions, using a direct connection, etc). I tried using Wireshark to capture the traffic when it boots up but I don't see any traffic coming from the iSCSI card although the orange lights on the NIC's flash when plugged in.

I tried both network ports and I get the same result - just flashing orange lights and nothing meaningful in the captured traffic, no IP addresses, no response to pinging 10.10.10.10.

Is there a utility program I can use to find the IP address of the bridge? I heard someone mention that there's a program called LAN Scan that will get the bridge to respond and reveal it's IP address. Is there a place I can download it or can someone share it with me?

Thanks!

Hi, When you did the direct connection did you use a straight through cable or a crossover cable? Was the module purchased from us?

I used a standard CAT 5E cable from my laptop to the iSCSI bridge; I tried both ports next to the SAS port with the same result. Whatever port I used on the bridge both orange lights would light up and blink and my laptop shows a 1GB connection. The SAS connector is connected to the LTO-5 drive in my TL2000 and there is a green light on the back of the iSCSI bridge, so apparently the bridge sees the tape drive.

I tried the settings in the manual for my laptop's NIC (10.10.10.11 - 255.255.255.0) and using Wireshark to capture the traffic. All I get is traffic from my NIC, nothing from any other IP.

I also tried flashing the TL2000 and resetting it to factory defaults - nothing. It seems like the iSCSI bridge only uses power from the TL2000 and doesn't directly communicate with it so there's no way to reset it back to defaults without knowing its IP address.

I purchased it used from an online company.

Is there a Dell utility program that will ping the bridge and get it to respond to reveal it's IP?

I do not see a standalone tool, Openmanage essentials might be able to discover it though. http://en.community.dell.com/techcenter/systems-management/w/wiki/1989.openmanage-essentials

Someone mentioned a program called LANSCAN that was supplied by Dell support in this thread:

http://en.community.dell.com/support-forums/storage/f/1216/t/19593746

"Carlos,

I ran into the same issue as you and I was able to solve it by using a utility that Dell support provided to me called LANSCAN. This utility sends out a broadcast to the iSCSI card which then responds back with its IP address and other information. It worked really well. Contact Dell support and ask them for the utility."

I have OpenManage installed but I don't see anything that would help.

The LANSCAN tool mentioned doesn’t look like a Dell tool, just a 3rd party IP scanner.

I ran Angry IP scanner through all of the common private IP addresses (10.0.0.1 ~ 10.255.255.255, 192.168.0.0 - 192.168.255.255 and 172.16.0.0 - 172.31.255.255) and received no response. Nothing. If it came from a large corporation the IP could be set to almost anything, but it would take forever to ping every possible address. It's just not worth my time.

The two orange lights on both network adapters are on and flash and there's a green light when you plug in the SAS cable; other than that, there's no sign of life.

I tried flashing the firmware of the TL2000, didn't change anything - I don't see anywhere in the web management of the tape library where it's 'aware' of the presence of the iSCSI bridge; although nobody seems to have a clear answer whether it will see it or not.

I tried resetting the TL2000 back to defaults, it had no effect on the iSCSI bridge.

I'm really surprised this thing doesn't have a reset button or a jumper and there's no utility program available from Dell that could find it once the network IP is changed from defaults. It also seems strange that the tape library itself has no way of communicating with the card - it almost seems like an afterthought and poorly integrated.

At this point, after spending hours trying to get it to work, I'm assuming it's defective since it shows no network traffic at all using Wireshark and doesn't respond to any private IP address pings.

Hello BSD2000,

Thanks for the service dump log. After reviewing the log I can see both of your drives, but I am not seeing your ISCSI bridge as present on your LTO5 drive. For that I would say that your bridge is not working. I see that you state that the lights come on when the network & sas cables are plugged in. There is no way of getting the ip address using the web utility. I would say that your ISCSI bridge is not booting fully, & that is why you are not seeing it when you are using a scan tool.

Please let us know if you have any other questions.

Thanks for the follow up. I figured there had to be something wrong when it showed no network traffic and the tape library didn't recognize it. I contacted the seller and started an RMA so at least it's not a total loss.

Thanks again for your help!

Sam,

Just to put this subject to an end, we buy used, off lease equipment. We recently got 2x TL2000 libraries with x2 LTO6 drives and 1x iSCSI card installed off lease. What you are saying is that if the default 10.10.10.10 has been changed, there is no possible way to discover what it is? We tried scanning, etc. and have had no luck on either one. We did get the IP addresses for the libraries, but apparently the iSCSI cards are not on same network. So both of these iSCSI cards are junk without knowing what the IP was changed to, correct?
