To Test A Switch's Internal Components; To Test Components To And From The Hba - HP AA979A - StorageWorks SAN Switch 2/8V Administrator's Manual

To test a switch's internal components

1. Connect to the switch and log in as admin.
2. Connect the port you want to test to any other switch port with the cable you want to test.
3. Enter the crossporttest -lb_mode 5 command where 5 is the operand that causes the test to be
run on the internal switch components (this is a partial list—refer to the Fabric OS Command Reference
Manual for additional command information):
[-nframes count]—Specify the number of frames to send.
[-lb_mode mode]—Select the loopback point for the test.
[-spd_mode mode—Select the speed mode for the test.
[-ports itemlist]—Specify a list of user ports to test.

To test components to and from the HBA

1. Connect to the switch and log in as admin.
2. Enter the fPortTest command (refer to the Fabric OS Command Reference Manual for information
on the command options).
switchname:admin> fporttest 100,8,0xaa55,2, 512
Will use pattern: aa55
Running fPortTest ........
port 8 test passed.
value = 0
This example executed the fPortTest command 100 times on port 8 with payload pattern 0xaa55,
pattern width 2 (meaning word width) and a default payload size of 512 bytes.

for a list of additional tests that can be used to determine the switch components that are
Function
A read and write test of the ASIC SRAMs and registers.
Functional test of internal and external transmit and receive paths at full
speed.
Verifies that the data written into the miscellaneous SRAMs in the ASIC are
retained after a 10-second wait.
Verifies the functional components of the switch.
Verifies that the on chip SRAM located in the 2 Gbit/sec ASIC is 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.
Verifies that the ASIC statistics counter logic.
Restricts the items to be tested to a smaller set of parameter values that you
pass to the switch.
