About the DAFS diagnostic tests

DAFS tests the functioning of the Emulex VI cards that are in your system. The tests range from EEPROM check through the testing of data movement through the system. The DAFS diagnostic tests can generate error messages associated with the hardware and software.

Note: Tests that are labeled [Xtnd] often require loopback plugs for complete test operation and will indicate failures without these plugs.

Caution: Do not run [Xtnd] mode diagnostics on network adapter cards with live network connections. Disconnect all network connections prior to running network diagnostics in [Xtnd] mode. Running with attached networks can adversely affect other attached devices. Type xtnd n to cancel Extended test mode.

DAFS diagnostic test menu

The following table describes the tests in the DAFS diagnostic test menu.

Test no	Test	Description
1	Comprehensive test	Runs all tests in this menu in current mode.
2	EEPROM verify	Verifies EEPROM checksum.
3	MAC loopback	Internal MAC loopback. Transmitted data loopback at MAC level and travel across the PCI bus in the opposite direction.
4	SERDES loopback	Internal serializer/deserializer (SERDES) loopback test. Transmitted packets loop back at the SERDES and travel across the PCI bus in the opposite direction.
5	External loopback [Xtnd]	Off board loopback test. Transmitted packets loop back at the external cable.
6	Interrupt test	Tests the interrupt mechanism.
7	DMA diag	Off board loopback test. Transmitted packets loop back at the external cable.
8	Stress MAC	Host PCI bus and internal MAC loopback stress test.
9	Stress SERDES	Host PCI bus and serializer/deserializer loopback stress test.
10	Stress External [Xtnd]	Checks and displays the MAC address of the card.
11	Warm reset card	Host PCI bus and off board loopback stress test.
70	Display MAC address	Displays the MAC address of the card.
71	Display EEPROM	Displays the onboard Electrically Erasable Programmable Read Only Memory (EEPROM) contents.
72	Display HBA clock frequency	Displays onboard clock frequency.
73	Display card information	Displays card serial number, MAC address, part number, card revision ID, and firmware revision.
91	Enable/disable looping	Enables or disables continuous running of a diagnostic test. The test is stopped when Ctrl-C is pressed or when an error is encountered if option 92 is active.
92	Continue/stop looping on error	Starts or stops running a diagnostic test on an error. If looping is enabled, as set by option 91, looping continues after an error is encountered.
93	Extended/normal test mode	Enables or disables extended mode on tests where extended mode is an available option.
95	Long/Short loopback test mode	Enables or disables long loopback test mode. Long loopback test usually runs for several hours and is mainly used by manufacturing to stress the card.
99	Exit	Exits diagnostics.
