14. Repeat steps 6 - 12 for all ports until:
— the number of frames requested is reached.
— all ports are marked bad.
15. (Optional) Disable SFP mode. If you entered setsfpmode , the mode
remains in volatile memory until it is disabled. Enter setsfpmode 0 .
Additional Component Tests
The following list displays additional tests that can be used to determine those
switch components that are not functioning properly. Refer to the HP
StorageWorks Fabric OS Version 3.1.x/4.1.x Reference Guide for details on these
tests.
Table 18: Switch Component Tests
Test Function
portloopbacktest Functional test of port N->N path. See “ Check Port’s
External Transmit and Receive Path” on page 225 .
portregtest A read and write test of the ASIC SRAMs and registers.
spinsilk Functional test of internal and external transmit and
receive paths at full speed.
sramretentiontest Verifies that data written into the miscellaneous SRAMs
in the ASIC are retained after a 10 second wait.
crossporttest Verifies the functional components of the switch.
turboramtest Verifies the on chip SRAM located in the 2 Gbit/sec
ASIC using the Turbo-Ram BIST circuitry. These same
SRAMS are tested by portregtest and sramretentiontest
using PCI operations, but for this test, the BIST controller
is able to perform the SRAM write and read operations
at a much faster rate.
statstest Verifies the 2 Gbit/sec ASIC statistics counter logic.
