UCS: Blade is stuck in EFI Shell, service profile association stuck

by on Dec.11, 2013, under Cisco, UCS

After associating service profile to a blade it gets stuck in EFI Shell and association can not complete.
The KVM is showing EFI Shell

FSM status is stuck on Configure Apply Config

The problem could be because the service profile does not have all the required configuration. Have a look at Status under General tab to see what is the error.

In this case there were no MACs or WWPNs defined. CNA cards must have these defined as they do not have them burned in.

Using Cisco UCS Blade Server Diagnostics

by on Nov.15, 2013, under Cisco, UCS

Cisco has released Cisco UCS Blade Server Diagnostics.
It’s an ISO file that you boot your blade from and there you can run a series of test to find out if there are any problems with hardware.

To run UCS diagnostics do the following:

  • Download ISO file from cisco.com you’ll need login first. At the time of writing the only version available is 1.0.1a
  • Login to UCS Manager and open the KVM console on the blade that you want to test(the blade must be associated with service profile and CD-ROM must be present in Boot Order at the top of it)
  • Select Virtual Media tab, click on Add Image button, locate and select Cisco UCS Blade Server Diagnostic ISO file that you downloaded. Make sure that Mapped box is ticket next to ISO file.
    1
  • Restart the server. The server should start booting form ISO file
  • You’ll be prompted to choose from 3 options(GUI, CLI, memtest86+) if you do not choose in 10sec the blade will into GUI
    2
    GUI and CLI are self explanatory. memtest86+ is RAM testing utility.

UCS: flashing cursor after installing Linux (RedHat, Suse), server would not boot

by on Jan.04, 2013, under Cisco, UCS

Here is an interesting thing that happens during Linux installation on Cisco UCS blade.
After installing Suse on Cisco UCS blade, the server would not boot and only flashing cursor is seen. Tried other version of Suse and even RHEL, still the same. This looked strange because I had installed Linux on UCS without any problems before.
There is a small thing that you need to be aware when doing installation. Make sure to add CD-rom in boot order in the the service profile and after you mount your ISO let the sever to pick it up itself. Do not press F6 and choose for it as this is where interesting thing happens.
When you let the server to pick the boot device it makes Linux installer to think that this server is running in UEFI mode.
When you press F6 and choose the boot device the installer thinks it is BIOS mode and when partitions are created, it messes things up there for after reboot you see flashing cursor.
