Bpturboramtest - Brocade Communications Systems 8 Command Reference Manual

bpTurboRamTest

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. chassisdisable
2. slotstatsclear
3. diagclearerror -all
4. cryptocfg --disableEE (if the encryption engine is in enabled state)
The test flow for each SRAM is as follows:
1. Fill RAM with alternating FFFF 0000 pattern. (Subtest 1: turboram memory fill)
2. For each incrementing address read FFFF 0000 pattern and write 0000 FFFF. (Subtest 2:
3. For each incrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 3:
4. For each decrementing address read FFFF 0000 pattern and write 0000 FFFF. (Subtest 4:
5. For each decrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 5:
6. Repeat steps 1-5 with AAAA 5555 pattern.
Notes This command is currently supported only on the Brocade Encryption platform. 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

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.
