Gbe2 "Unknown Rack ID and Enclosure Information"

[Henrik Lorendahl]

Under Switch Information in the dashboard, switch dosen´t report the correct infrastructure information. See attached Word document for all details.
I have solved it once (i think), connect to the Serial Port back at the Management Module and Choose submenu S=RACK and reenter the Serial Number of the Blade Enclosure and apply. Restart Manangement Module and it worked that time. Tried on other Blade Enclosures but no success. How is it possible to change this information

Do you have the latest image on the interconnect switches, power management modules, and ILO's?

These are all critical pieces, especially the pmm firmware all being at 2.10 and the interconnect switch image being newer.

I noticed on ours that the interconnect switches with the latest firmware image and the power management module firmware all being at 2.10 that it all works fine. I would also make sure your ILO's are all at 1.70.

Are you seeing any chksum or other weird errors on the enclosure for it's serial number? That caused us some issues and was resolved by replacing the signal backplane in the enclosure.

That information is configured through the ILO that the interconnects is pulling. I would upgrade all your ILO's to 1.70, but before you do make sure using the Rack Infrastructure update utility within one of the blades in the rack that you download the latest firmware which is 2.10.

I attached the firmware image for the rack infrastructure. You can download the latest ILO from support and drivers at.

The ILO and rack infrastructure are absolutely critical that they are running at the latest out there. I know because I have been working for 3 months with the HP engineers in Houston on are various issues.

Once the ILo is at 1.70 go into the ILO, go to the BLP class tab, and rack view. This will not work unless all of your enclosure firmware is at 2.10 and your ILO's are all at 1.70. Once that is set then you go into the details link on the enclosure of the blade ILO you are in and name the rack, and the enclosure. You can configure the rack name from any blade ILO in the rack, but you have to go into an ILO that is physically located in the enclosure you want to rename to rename each enclosure. If you have 4 blade enclosure you will need to go inot 4 seperate blade ILO's to correctly rename all the enclosures. What I do is name them Rack1 for the first blade rack, then the first enclosure is A, the second enclosure is B, and so on.

Hope this helps

Hi,

I have upgraded every component in this Blade Solution to "Latest and Greatest".
But it hasn´t changed status, but I tried a solution that worked, very strange.

Unscrew the serial port plastic kit from the Management Module and connect a PC/Server to it and check the Serial Number
(E=Serial Number). Then it reports the correct serial number, but I changed it to exactly the same, just made some kind of change in the Management module, then it WORKED.So "ReEnter" the Blade Enclosure Serial Number and then reset all Management Modules. You have to do this one module then reset all management modules.

That is very odd because all the other information you are looking for such as rack name, enclosure name, are only configured in the ILO boards. Everything in the ILO is correct as well?

I have seen tons of very odd issues such as this with the HP blade systems and we are actually looking at the IBM bladecenters now just to get a feel for their solution, because we are feed up with the HP systems unreliability lately. The fears we had when they bought compaq are all to real now.

Henrik,

The reason changing the serial number worked is because the serial number you changed made a change in the signal backplane of the neclosure. Changes to the signal backplane trigger an interrupt in the switch to make it re-read the enclosure data. You can easily do this remotely by going into iLO and changing the rack or enclosure name and then changing it right back.

This should not ever need to be done, however. Make sure you have the latest GbE2 firmware and the latest enclosure firmware (coincidentally, they are both at version 2.20 right now).
