How do I use OMSA to identify a faulty CPU & have it replaced on a Linux server?

If you do encounter an error related with a server’s CPU (Processor) and you wish for it to be replaced, and if there is more than one CPU in this server, you will need to provide as much of the following information as possible about the faulty CPU, to allow our technicians to correctly identify which CPU needs replacing:

1. The failed CPU’s slot number (i.e. the Connector Name)

2. The failed CPU’s Make and Model (i.e. Processor Brand information)

If your server only has one CPU installed, we do not require this information to locate and replace the CPU. Please feel free to raise a support ticket and we will be happy to help.

If you do have more than one CPU in the server, this information will aid the technician in locating the failed CPU and swapping it with the correct replacement CPU. You can use Dell EMC’s OpenManage Server Administrator (OMSA) application to find this information.

To find this information, you must first be logged into the server’s root account and you must have located the CPU with the error. Please see the sections on accessing OMSA if you are unsure on how to access OMSA. To find the details about the processors configured in the server, run the following command:

Processor (CPU) - Command 1
Command Description	Run the following command to bring up a list of what Processors are configured within the chassis, their status and their details.
Command	omreport chassis processors
Image of Command being Run
Image of a Successful Result of Command

Here you will be able to see a list of the CPUs installed in the server, their make and model, their connector name and their specifications. If a CPU appears with an error and you wish for this CPU to be replaced, you will need to supply all the information about this CPU that appears in the results from this command in a support ticket, so that our technician can identify the failed processor and replace it. You can also supply a screenshot of this page.

Occasionally, if a CPU completely fails, it may not appear on this page with an error, but might actually be missing from this page all together. If this is the case, then you will not be able to find the information above on the failed CPU, to get it replaced. Instead, you can provide the information on all the CPUs that are present, so the technicians can locate the failed processor through a process of elimination. You can also supply a screenshot of this page.

Once you have provided all the above information in a support ticket, the technicians should be able to locate and replace the faulty CPU.
