Description |
---|---|
Connection Test |
In this mode, 1 percent of the memory is read; pmemtest also informs the user how much physical memory is available. For sun4m, sun4u, and UltraSPARC servers, the test reports the ECC errors that have occurred since it was last invoked. The test reports ECC errors for a particular CPU or memory board when physical mapping is selected, otherwise it provides the SIMM number of the ECC memory error. |
Functional Test |
In Functional test, the amount of memory to be read can vary; the default is 100 percent. For UltraSPARC servers, this test mode reports all ECC errors that have occurred since the system was brought online |
Functional Test mode through SyMON |
When pmemtest is invoked through SyMON, the following Functional Test description applies: A variable amount of memory is read; the default is 100 percent. For UltraSPARC servers, the ECC error reporting is the same as for the Connection test. |
