bpTurboRamTest

bpTurboRamTest - MBIST test for AP Blade BP ASICs.

Synopsis bpturboramtest [--slot slotnumber][ -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:

turboram r-m-w inc 1)

3. For each incrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 3:

turboram r-m-w inc 2)

4. For each decrementing address read FFFF 0000 pattern and write 0000 FFFF. (Subtest 4:

turboram r-m-w dec 1)

5. For each decrementing address read 0000 FFFF pattern and write FFFF 0000. (Subtest 5:

turboram r-m-w dec 2)

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 slotnumber Specifies the slot number on bladed systems.

-passcnt count Specifies the number of test repetitions. By default the test runs once.

-bpports itemlist 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.
