Fixed an issue that caused Tx to hang when a duplicate packet rollback occurred. 4. Fixed an issue that prevented events from being sent when only the DCBX oper version was changed. 5. Fixed an issue that prevented a SFP28 cable from linking up in a 25GbE speed. 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. Please Update To The Latest Level At Your Earliest Convenience 14.29.1017 / 001400291017 Impact: Availability Severity: ATT 1. Update to Fcode - Fixed an issue with the TX buffer index not properly wrapping causing iSCSI boot to fail. 2. Fixed an issue that caused packets to drop due to header size issues and/or failing checks. The issue was caused due to a Linux issue that caused VFs to set the wrong header size value in wqe_inline_header_mode input. 3. On rare cases, a fatal error related to errors from the PCI transport layer might be reported during FLR. 4. Fixed an issue that caused the device to go to dead IRISC as one of the firmware semaphores could not be released when a speed change or port state change was triggered. 5. Fixed a rare race condition that caused an erroneous write to the firmware image during certain power-down scenarios. This resulted in firmware being recognized as invalid and prevented the adapter card from being recognized by the system due to missing valid Flash images. 6. Fixed an issue that caused the sent packet to hang while the device entered FLR mode. 7. Enabled bytewise BAR configuration. 8. Fixed a rare case where the device hung while running the sw reset flow under heavy stress and with many open resources. 9. Fixed an error that prevented the completions (CQ) from being completed due to a race condition in the firmware transport error handlers. 10. Fixed an issue that cause fragmented IP packets to drop. 11. Fixed a firmware fatal assert that showed an IRISC HANG due to init_hca 12. Fixed a performance degradation issue, and a high packet drop when SR-IOV was enabled and packets went through the FDB default behavior. 13. Fixed a rare issue that caused other active functions to receive a malformed CQE during driver (PF or VF) unload or FLR flows. 14. Fixed an issue that caused the firmware to hang when an FLR occurred at the same time as the teardown. Please review comments about SRIOV and AIX APARs in General Information section of this release notes. 14.24.8000 / 001400248000 Impact: Availability Severity: ATT 1. Adds Secure Fcode support 2.

If the version is less than 14.31.1014, 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. A. Transfer the RPM format file to the /tmp directory (using “Save as....”). You will see the filename for the RPM file.  B. Install rpm on your Linux system by typing: rpm -ivh /tmp/b315151014101e06.001400311014.Linux.rpm The microcode package will install the firmware images in the /lib/firmware directory. If a message is displayed saying the "package is already installed", you will need to uninstall the listed rpm package. On the command line type: rpm -e where is the name of the package that was returned in the message. Return to Step 2 and attempt to install the file again. C. 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/b315151014101e06.001400311014 to verify file size: * b315151014101e06.001400311014 = 16744768 sum /lib/firmware/ b315151014101e06.001400311014 to verify Checksum: * b315151014101e06.001400311014 = 63317   6.

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 7.2 with Technology Level 2 and Service Pack 2 and above * AIX 7.1 with Technology Level 5 and Service Pack 2 and above * AIX 7.1 with Technology Level 4 and Service Pack 6 and above * VIOS 2.2.6.21 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 PCIe3 2 PORT 25/10 Gb NIC&ROCE SR/Cu ADAPTER installed in the system by typing: lsdev |grep b315151014101e06 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 001400311014 If the ROM Level is less than 001400311014 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 b315151014101e06.001400311014.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: b315151014101e06.001400311014   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. 9.0 Discovery Tool Microcode CD-ROM creation and download instructions To obtain information how to burn a CD-ROM and run the Discovery Tool for an AIX or Linux System please go to: http://www-304.ibm.com/webapp/set2/firmware/lgjsn?mode=10&page=cdrom.html 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 A. At the command line type "diag" B. Select the "Task Selection" from diagnostics menu. C. Select "Microcode Tasks” then select “Download Microcode" from the menu. D. Select all of the entX PCIe3 2 PORT 25/10 Gb NIC&ROCE SR/Cu Adapters that need to be updated from the list of devices by using the arrow keys to highlight the entry and pressing "Enter" to mark it.  Press "F7" or "ESC+7" when you are done marking all the adapters you want to flash. E. If a source selection menu is displayed, Select "/etc/microcode". F. A dialogue box may be displayed on screen.  It will state that the current microcode level on the adapter is not in the /etc/microcode directory.  This is acceptable because the adapter will reject any incorrect code.  Press "Enter" to continue. G. Select 001400311014 level and press "Enter" to flash the adapter. H. The following message will appear on the screen when download is completed: "Microcode download complete successfully.  The current microcode level for the device is ...  Please run diagnostics on the adapter to ensure that it is functioning properly."  I. If you selected more than one adapter to update, then steps 6-9 will repeat until all adapters are updated. J. Exit diagnostics. 11.3 Re-configure and Verify adapters A. Run "cfgmgr" to reconfigure the adapters that were moved to defined before the update.  B. Verify the code level is 001400311014 by typing "lsmcode -cd entX" for each adapter updated, where "X" is the instance of the PCIe3 2 PORT 25/10 Gb NIC&ROCE SR/Cu ADAPTER.
