when I power on my sun netra 240 server,
it displays this error messages:
1. Notice: cpu 0 has 2048/2048 MB of memory disabled.
2. Error : The following devices are disabled dimm1.
Please can anyone be kind enough to explain this for me?
I think there is a way to display memory diagnostics from the PROM level but
I'm not sure what it is from your hardware. The .asr interface comes to mind
but you might have to check the netra 240 doc to know for sure.
Run a max diag POST by changing the below OBP variables and power cycle the server.
or run below command to run max diag POST without changing variables.
ok>post max max
During POST it will throw the J numbers of the faulted memory. Replace the same. Seems ur server is having only one bank which consists of two memory.
Thanks to all those who responded to this question. You inputs where helpful. I should have done A+. I figured out the issue and now understand that a dimm is a memory. Studied fault management and was able to figure out that one of my cpu's was retired.
