I haven't worked on these machines much but I got called into out IT department to look at a 51A they were removing memory from. It had 4 GB sticks installed. They wanted to move two sticks to another server. We they removed the two sticks the remaining two sticks were in the correct slots per the documents (C12 and C5).

After powering back up the machine comes up with the error B181F7BB. I am not sure if this is a serviceable error or not.

Years ago on the RS6000's we had to run cfgmgr when removing equipment or the system would error. Is there still something to this?

A google for the code suggests there is either a cpu voltage regulator configuration problem, for which it seems there may be a firmware fix but as you have only removed memory this is unlikely.

Otherwise it seems you need to check the service processor error logs for more info.

For a memory change the cfgmgr that runs during boot will sort out the new config, so nothing to worry about there.

Thanks for the reply. I asked my sys admin about checking the error logs and didn't know how

This is what I found in one of the IBM doc's.

B181F7BBThe system resource(s) in the callout list failed a system configuration test

Does it boot?
If so, run the diag command and then select advanced diags, problem determination, select all resources and f7 to run, see what it tells you.
If it wont boot then at standby (just power connected but not booted) either connect a dumb terminal to the serial port or a web browser to the hmc port and log in to the ASMI and check the error logs.
