Server Diagnostics Mac OS X Tests

These tests are available if your server is running Server Diagnostics Mac OS X.

Startup Tests

These tests run automatically when you start up Server Diagnostics Mac OS X.

SMBIOS tests check to see if bad memory was detected and mapped out at server

startup. When the server tests memory at start up, it automatically maps out bad

memory. Mac OS X doesn’t see this mapped out memory, so the non-SMBIOS memory

tests don’t test it. The SMBIOS test reports these mapped out DIMMS.

When an ECC error occurs, memory catches the problem and and xes it. When you

run other memory tests, the tests don’t realize an error has occurred. The ECC tests

detect these memory xes and report them.

Test Estimated completion time Description

Hardware Existence 1 second Compares a table of sensors and

fans with what’s connected to

the logic board. If a sensor or

fan isn’t found, an error occurs.

All sensors, fans, and hard drives

found can be individually tested

using sensor, fan, hard drive

tests.

SMBIOS Self-Test 1 second Checks the SMBIOS tables for

32-bit errors (type 18) and 64-

bit errors (type 33). Also veries

that the mapped-in DIMM size

is appropriate for the slot it’s

inserted into. If there’s a size

mismatch, an error occurs.

ECC Error Count 1 second Reports the number of ECC

errors, and then resets the

count.

AirPort Tests

Test Estimated completion time Description

AirPort MAC Address Verication 1 second Veries MAC address isn’t all FFs

or 00s.

AirPort Power Cycle 10 seconds Veries AirPort by performing

a wireless scan after turning

AirPort power o, then turning

AirPort power on.
