2. Verify that the switch prompt is displayed on a workstation connected to the switch.
If there is no switch prompt when POST is complete, press Enter . If the switch prompt still does
not appear, open a Telnet session or access the switch through another management tool. If
this does not solve the problem, the switch did not complete POST successfully. Contact your
switch supplier for repair.
3. Review the switch system log for errors.
Any errors detected during POST are written to the system log, accessible through the
errShow
command.
For information about error messages, see the Fabric OS Message Reference Manual.
Boot
Boot occurs after POST is complete and includes the following tasks:
•
Performing universal port configuration.
•
Initializing links.
•
Analyzing the fabric.
If any ports are connected to other switches, the switch participates in a fabric configuration.
•
Obtaining a domain ID and assigning port addresses.
•
Constructing unicast routing tables.
•
Enabling normal port operation.
Switch maintenance
The switch supports only HP-branded 8 Gb/s and 16 Gb/s SFP+ optical transceivers. For the FC
connections, the switch uses SFP+ transceivers that support any combination of SWL, LWL, and
ELWL optical media.
If you use an unqualified transceiver, the
switchshow
command output shows the port in a
Mod_Inv
state. Fabric OS also logs the issue in the system error log.
For information about installing transceivers, see “Connecting devices” (page 29) .
Diagnostic tests
In addition to POST, Fabric OS includes diagnostic tests to help you troubleshoot the hardware
and firmware. This includes tests of internal connections and circuitry, fixed media, and transceivers
and cables.
The tests are implemented by command through a Telnet session or a console set up to the serial
connection to the switch. Some tests require that ports be connected by external cables in order
to verify the serializer/deserializer interface, transceiver, and cable. Some tests require loopback
plugs.
Diagnostic tests run at a link speed of 2, 4, 8, 10, or 16 Gb/s (FC), depending on the speed of
the link being tested and the type of port.
NOTE:
•
Diagnostic tests can temporarily lock the transmit and receive speed of the links.
•
HP does not support 2Gb connectivity to the SN6000B or the SN3000B switches.
For information about specific diagnostic tests, see the Fabric OS Troubleshooting and Diagnostics
Guide.
