If such ini file cannot be found in the firmware directory, you may want to dump the config-

uration file using mstflint. Run:

Step 4. Edit the ini file that you found in the previous step, and add the following lines to the [HCA]

section in order to support 63 VFs.

Step 5. Create a binary image using the modified ini file. Run:

The file <file name>.bin is a firmware binary file with SR-IOV enabled that has 63 VFs. It

can be spread across all machines and can be burnt using mstflint, which is part of the bun-

dle, using the following command:

4.13.7 Configuring Pkeys and GUIDs under SR-IOV

4.13.7.1 Port Type Management

Port Type management is static when enabling SR-IOV (the connectx_port_config script will

not work). The port type is set on the Host via a module parameter,

port_type_array, in

mlx4_core. This parameter may be used to set the port type uniformly for all installed Con-

nectX® HCAs, or it may specify an individual configuration for each HCA.

This parameter should be specified as an options line in the file

/etc/modprobe.d/

mlx4_core.conf

For example, to configure all HCAs to have Port1 as IB and Port2 as ETH, insert the following

line:

To set HCAs individually, you may use a string of

Domain:bus:device.function=x;y

For example, if you have a pair of HCAs, whose PFs are 0000:04:00.0 and 0000:05:00.0, you

may specify that the first will have both ports as IB, and the second will have both ports as ETH

as follows:

# mstflint -dev <PCI device> dc > <ini device file>

;; SRIOV enable

total_vfs = 63

num_pfs = 1

sriov_en = true

1. Some servers might have issues accepting 63 Virtual Functions or more. In such case, please set the

number of "total_vfs" to any required value.

# mlxburn -fw ./<fw name>mlx -conf <modified ini file> -wrimage <file name>.bin

# mstflint -dev <PCI device> -image <file name>.bin b

After burning the firmware, the machine must be rebooted. If the driver is only

restarted, the machine may hang and a reboot using power OFF/ON might be required.
