Description:
Info
On an HPE system running Red Hat Enterprise Linux 8, the "mlnx_tune" script does not complete as shown below: [root@localhost ~]# /usr/sbin/mlnx_tune Traceback (most recent call last): File "/usr/sbin/mlnx_tune", line 3454, in <module> force_sw_dependencies(options.profile) File "/usr/sbin/mlnx_tune", line 3033, in force_sw_dependencies if "mlx" not in output: TypeError: a bytes-like object is required, not 'str'
Scope
Any HPE system running Red Hat Enterprise Linux 8 and attempting to run the "mlnx_tune" script included with the following driver versions: MLNX OFED 4.7-1.0.0.1 for Red Hat Enterprise Linux 8 MLNX-OFED 4.6-1.0.1.1 for Red Hat Enterprise Linux 8 Mellanox Ethernet+RoCE driver v4.7 (mlnx-ofa_kernel-4.7) for Red Hat Enterprise Linux 8
Resolution
Red Hat Enterprise Linux 8 installs the Python 3 package by default. The current version of "mlnx_tune" script does not support Python 3. As a workaround, run the script with Python 2 after installing the Python 2 package from the OS repository as described below: Install Python 2 if not already installed, by typing the following command: # yum install python2 Note : The OS YUM repository must be setup to use the above installation command. Run the "mlnx_tune" script explicitly with Python 2 as shown in the example below: # python2 `which mlnx_tune` -p HIGH_THROUGHPUT Alternatively, the following changes can be done to the script to make it use "python2" permanently. a. Type the command # vim /usr/sbin/mlnx_tune b. The First line is #!/usr/libexec/platform-python c. Remove "!" from this line, as follows: #/usr/libexec/platform-python d. Above #/usr/libexec/platform-python, add the line #!/usr/bin/env python2.7 e. Save the file. The file should display as shown below. f. Run "mlnx_tune" as is, for example, # mlnx_tune -p HIGH_THROUGHPUT RECEIVE PROACTIVE UPDATES : Receive support alerts (such as Customer Advisories), as well as updates on drivers, software, firmware, and customer replaceable components, proactively via e-mail through HPE Subscriber's Choice.
