Bpturboramtest - Brocade Communications Systems Brocade 8/12c Command Reference Manual

bpTurboRamTest

MBIST test for AP Blade BP ASICs.
SYNOPSIS
bpturboramtest [--slot slot]
[ -passcnt count ]
[ -bpports itemlist ]
DESCRIPTION
Use this command to verify the on-chip static random access memory (SRAM) located in the Blade
Processor (BP) ASICs of the Application Processor (AP) blade. The command makes use of the memory
built-in self-test (MBIST) circuitry.
Before running this diagnostics, you must disable the chassis and clear all logs using the following
command sequence:
1.
2.
3.
4.
The test flow for each SRAM is as follows:
1.
2.
3.
4.
5.
6.
NOTES
This command is supported only on the Brocade Encryption Switch. It complements the
bpTurboramTest, which tests the Condor2 ASIC on the switch.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
--slot slot
-passcnt count
-bpports itemlist

Execute chassisdisable
Execute slotstatsclear
Execute diagclearerror -all
Execute cryptocfg --disableEE (if the encryption engine is in enabled state)
Fill RAM with alternating FFFF 0000 pattern. (Subtest 1: turboram memory fill)
For each incrementing address read FFFF 0000 pattern and write 0000 FFFF. (Subtest 2: turboram
r-m-w inc 1)
For each incrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 3: turboram
r-m-w inc 2)
For each decrementing address read FFFF 0000 pattern and write 0000 FFFF. (Subtest 4: turboram
r-m-w dec 1)
For each decrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 5: turboram
r-m-w dec 2)
Repeat steps 1-5 with AAAA 5555 pattern.
Specifies the slot number on bladed systems.
Specifies the number of test repetitions. By default the test runs once.
Specifies a list of blade ports to test. By default all blade ports in the specified
blade are tested. Note that on the Encryption platform, ports 80-103 are the blade
ports connected to the BP ASICs. Refer to the itemList help page for further
information on the itemlist parameter.
