IBM Microcode Update Readme File

Firmware Level	Description
26.40.1000 / 002600401000	Impact: Usability Severity: ATT · Fixed a rare issue that prevented changes in mlxconfig from taking effect upon warm reboot. · Added a locking mechanism to protect the firmware from a race condition between insertion and deletion of the same rule in parallel. Such behavior occasionally resulted in firmware accessing a memory that has already been released, thus causing IOMMU / translation error.
The Firmware Levels Below Are No Longer Supported By IBM Once They Have Been Removed From The Microcode Download Website. It is best practices to update to the latest FW level not only for IBM support of these products, but for optimal performance and to ensure that all of the required HW/FW fixes are installed. Once new FW has been released to the field, we will provide a 6 month grace period for customers to update these products to the currently supported FW level.

5.0 Linux Requirements Error! Bookmark not defined.

For Linux operating systems, use the following procedure:

1. Find the PCI slot the 4 port ConnectX-7 adapter is plugged into. Issue the following command:

lspci -m -nn -d :101f|grep 06aa

For example:

# lspci -m -nn -d :101f|grep 06aa

0001:01:00.0 "Ethernet controller [0200]" "Mellanox Technologies [15b3]" "MT2894 Family [ConnectX-6 Lx] [101f]" "IBM [1014]" "Device [06aa]"

0001:01:00.1 "Ethernet controller [0200]" "Mellanox Technologies [15b3]" "MT2894 Family [ConnectX-6 Lx] [101f]" "IBM [1014]" "Device [06aa]"

Note:

a. This tells us that the adapter is in the PCIe slot 0001:01:00.0 which will be needed in next steps.

b. Each port is listed as its own PCIe ID

0001:01:00.0 – Port 0 of the adapter

0001:01:00.1 – Port 1 of the adapter

c. Either of the port PCIe IDs can be used to perform the microcode install.

2. Start MFT tools by running “mst start”

#mst start

Starting MST (Mellanox Software Tools) driver set

Loading MST PCI module - Success

Loading MST PCI configuration module - Success

Create devices

If the system does not have the mst command available, please install the Mellanox Firmware Tools (MFT) available here: http://www.mellanox.com/page/management_tools

3. Verify the current Firmware level by running “flint -d <pci bus ID> -q”. Replace <pci bus ID> with the ID found in the lscpi command from step 2.

# flint -d 0001:01:00.0 q

This command reveals the current version of the FW; which is 26.40.1000 in this particular case. If the version is less than 26.40.1000, please update.

4. Download the firmware RPM file to the destination machine.

Use this method to download the new microcode to a Linux system:

NOTE: The instructions that follow are specific Linux commands. Linux commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.

Transfer the RPM format file to the /tmp directory (using “Save as....”). You will see the filename for the RPM file.
Install rpm on your Linux system by typing:

rpm -ivh /tmp/b3151f101410aa06.002600401000.linux.rpm

The microcode package will install the firmware images in the /lib/firmware directory. If a message is displayed saying the "package <package_name> is already installed", you will need to uninstall the listed rpm package. On the command line type:

rpm -e <package_name>

where <package_name> is the name of the package that was returned in the message. Return to Step 2 and attempt to install the file again.

The microcode file will be installed to the /lib/firmware directory. The file name is：

5. Verify the contents of the image before flashing:

ls -l /lib/firmware/b3151f101410aa06.002600401000 to verify file size:

· b3151f101410aa06.002600401000 = 33554432

sum /lib/firmware/ b3151f101410aa06.002600401000 to verify Checksum:

· b3151f101410aa06.002600401000 = 63145

6. Update the FW with "flint -d <pci bus id> -i <image filename> burn"

# flint -d 0001:01:00.0 -i b3151f101410aa06.002600401000 burn

Current FW version on flash: 26.38.1002

New FW version: 26.40.1000

Burning FW image without signatures - OK

Restoring signature - OK

7. At this point we have burned the new FW on to the Mellanox adapter. However, this FW will not take effect till the system is rebooted.

Reloading the drivers is not enough; it requires the system linux partition to be rebooted.

6.0 AIX Requirements

Adapter is supported on:

· AIX 7.3 with Technology Level 2 and Service Pack 1 and above

· AIX 7.3 with Technology Level 1 and Service Pack 3 and above

· AIX 7.2 with Technology Level 5 and Service Pack 7 and above

· VIOS 4.1.0.10 and above

· VIOS 3.1.4.31 and above

If you are using another release of AIX, ensure that the adapter is supported on that release before you install the adapter. Contact service and support for assistance.

7.0 Determine the Current Microcode Level for AIX

Before you install the microcode, it is important to determine the microcode level of the Adapter installed in the target system. Use the following instructions to read the ROM level stored in the Adapter's VPD.

A. List all PCIe4 x8 2-port 25/10/1 GbE RoCE SFP28 adapter installed in the system by typing:
lsdev |grep b3151f101410aa06

B. To check the current microcode level for the adapter or controller enter the following command:

lsmcode -cd entX

Where "X" is the instance of the adapter. The command will produce output similar to:

# lsmcode -cd ent1

The current microcode level for ent1 is 002600401000

If the ROM Level is less than 002600401000 you should update the microcode.

8.0 Downloading the RPM Format File to the Target Server for AIX

Use this method to download to an AIX system:

NOTE: The instructions that follow are specific AIX commands. AIX commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.

A.    Make two directories on your AIX system to receive the RPM format file.
Enter:      "mkdir /tmp/microcode"
and then create this directory
Enter:      "mkdir /tmp/microcode/RPM"

B. Transfer the RPM format file to the /tmp/microcode/RPM directory (using "Save as ..."). Change to that directory, "cd /tmp/microcode/RPM".
You'll see the filename for the RPM file.
"rpm -ihv --ignoreos b3151f101410aa06.002600401000.aix.rpm"

C. For AIX: The microcode files will be added to /etc/microcode/.

D. Microcode file will be copied to "/etc/microcode". The file size and checksum of the microcode image will be verified in Section 10.0.
File Names:
b3151f101410aa06.002600401000

NOTE:
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated directory or file then the user will be prompted for a new location.

11.0 Microcode Download Procedure for AIX

11.1 Setting up for Microcode download

A. Stop all applications that use this interface/adapter.

B. Remove the interface/IP address from the all ports identified in section 7.0 for the adapters that will be upgraded.

a. Before detaching the interface, record the IP address and any other pertinent information that was configured on the Adapter. This information may be needed if the microcode update overwrites this section on the Adapter.

C. If the interfaces are members of an SEA, the SEA devices must be moved to a defined state.

a. "rmdev -l enX" - where "X" is the interface number for the Shared Ethernet Adapter.

b. "rmdev -l entX" - where "X" is the interface number for the Shared Ethernet Adapter.

D. If the interfaces are members of an EtherChannel, the EtherChannel device must be moved to a define state.

a. "rmdev -l enX" - where "X” is the interface number for the EtherChannel adapter.

b. "rmdev -l entX" - where "X" is the interface number for the EtherChannel adapter.

E. For every port associated with the adapter, the enX interfaces must be changed to a defined state.

a. "rmdev -l enX" - where "X" is the interface number for the adapter port.

b. This command will be run 2 times, once for each port on the adapter.

11.2 Downloading Microcode to the Adapter
