Appendix E. Setup procedures and diagnostics for the Fibre
Channel Hub
This appendix provides setup and diagnostic information for the IBM 3534 Fibre
Channel Hub, Model 1RU.
Note:
Throughout this section, the term
switch
refers to switches and hubs unless
otherwise noted.
General information
The hub is designed for maintenance-free operation. When there is a suspected
failure, the hub has self-diagnostic capabilities to aid in isolating any equipment or
fabric failures.
The hub supports power-on self-tests (POSTs) and diagnostic tests. The diagnostic
tests determine the status of the hub and isolate problems.
Telnet commands are used to determine the status of the hub, error conditions, and
hub operating statistics. A Telnet session can be established from the IBM
StorWatch SAN Fibre Channel Managed Hub Specialist. The same Telnet
commands can also be issued using the service terminal connected to the serial
port.
Attention:
Many of the diagnostic tests are disruptive to hub operation. Read the
information on each diagnostic before beginning a test or procedure.
Isolating a system fault
Various loopback paths are built into the hub hardware for diagnostic purposes. A
loopback path test within the hub verifies the proper internal Fibre Channel port
logic functions and the paths between the interfaces and central memory.
Diagnostics also supports external loops that include the system board and the
GBIC module in cross-port configurations. These port-to-port diagnostics allow you
to check installed fiber cables and perform port fault isolation.
Removing power
After all data transferring processes external to the hub are completed, removing
power from the hub does not disrupt the fabric.
Note:
Error messages are stored in random access memory (RAM) and are lost
when power is removed from the hub. Access the error message log to view,
and note any error messages before removing power from the hub.
Service actions for error messages
See “Error messages” on page 165 for error message descriptions and the
appropriate service actions.
Setting up partnering with the 3534 Fibre-managed hubs
The following steps allow you to re-partner the 3534 Fibre-managed hubs.
Note:
Partnering of the hubs is set up on the product before it is shipped to you.
