Here is an interesting issue that I ran into with Cisco UCS blade.
I needed to move service profile from one blade to another. This is a process that should not give any problems but it did. Dissociation worked fine, but when I tried to associate the same profile with diferent blade I ran into problems.

The first thing I noticed is Config Failure error in Status:

The Configuration error was:
connection-placement
There are not enough resources overall
Not enough vHBAs available
Not enough cNICs available (more…)

UCS: After installing or replacing DIMMs shown as disabled in UCS Manager(invalid FRU)

Here is a problem that you can see when replacing or installing new DIMMs in UCS Blades.
Although the blade will boot but the newly installed DIMMs might show as disabled with invalid FRU error:
Error codes F0844 and F0502 are logged:

When you check inventory of the blade and go into Memoery you’ll see that Capacity and Clock are Unspecified.

SSH into UCSM IP.
Type:
scope server x/y (where x is your chassis id and y is server id of the server that is having problems.)
show memory (this list memory information of the blade)
Server 1/1:
Array 1:

UCS: Blade is stuck on discovery after UCS firmware upgrade (unidentified FRU)

Here is pretty common problem in UCS 2.0 release.
At any stage of UCS upgrade one or more blades go into discovery mode and never finishes it. Depending on the version they can get stuck at any percentage but usually between 4% and 40%.
Most of the time a corruption occurs in SEEPROM of M81kr CNA card because of this corruption checksum fails and UCS cannot recognize the mezzanine card any longer and this prevent Discovery from finishing.
You can see the following errors when this happens:
Configuration Error: adaptor-inoperable. Discovery State: Insufficiently Equipped.
Adapter 1 in server 1/1 has unidentified FRU

There are multiple Cisco bugs for this issue CSCub16754, CSCty34034, CSCub48862, CSCub99354 and I’ve seen it happening on 2.0(1q), 2.0(2r), 2.0(3a) releases.
Unfortunately the issue is not fixed and there is no workaround. The good thing is that if this occurs the fix is pretty simple and quick and no hardware replacement is needed but only Cisco TAC can fix this or whoever has access to their internal resources.

To verify if corruption occurred you can do the following:

SSH to UCSM IP
Enter connect cimc x/y (Chassis/Blade)
Enter mezz1fru on the versions starting from 2.0(3a) you need to enter fru
If corruption has occurred the last line of the output will show something like
‘Checksum Failed For: Board Area!’

The other method to check is to look at the logs. (more…)

UCS: How to update Capability Catalog in UCS Manager

Here is a guide how to update the Capability Catalog in UCS Manager. Capability Catalog is updated every time you upgrade UCS firmware but you might need to update it separately when a new hardware is added to UCS infrastructure and upgrading the whole UCS is not possible.

1. Login into UCS manager
2. Select Admin tab and change the Filter to Capability Catalog

3. Verify the version of Capability Catalog that is currently installed

UCS: IOM POST failure, Code: F0481

So I’ve got the following error on Cisco UCS IOmodule it came out of nowhere.

left IOM 4/1 (A) POST failure
Code: F0481

So the fix could be very simple try reseating or resetting the IOmodule that is giving the problem.
Before you attempt to do that make sure that you the other IOmodule in the Chassis is working fine and all the blades in the chassis have other path available when the IOmodule is reseated. If you have only one IOmodule then you would need to power down the blades first.

Here I’ll show how to reset IOmodule from UCSM.

First select the IOmodule that is giving problems and click Reset IO Module

You’ll be prompted to confirm

You should see now that IOmodule is not reachable and one path for Chassis is down.
Also Critical errors and Warnings will be logged.

Wait for the IOmodule to comeback and the errors to clear.

If all is clear then monitor this module for couple weeks or so. If the same Error appears on IOmodule then call Cisco support to get the module replaced. I’ve seen where the error would reappear after 2-7 days. In that case call Cisco support to get IOmodule replaced.

Cisco has released new firmware 1.0.03 for Linksys E4200

So if you like me have Cisco/Linksys E4200 router and was able to connect using 5GHz over bigger distance to get the maximum performance then quickly go here and get the latest 1.0.03 firmware and upgrade you E4200 router.
I’ve been using this router for couple months(firmware 1.0.02) but I was not able to connect over 5GHz if I was sitting in my office in 1st floor(the router is on the ground floor). It looks like Cisco did something in new 1.0.03 firmware, because as soon as I upgraded to a new firmware version my computer reconnected on 5GHz which means that I can get up to 450Mbps instead of 144Mbps.
