4.1.2 Removing Corrupted Configuration Files
In certain cases the old connectx_port_config script may leave behind some bogus port configu-
ration. To delete them, follow the steps below:
1. Retrieve the current configuration string. Run:
 On ESX:
cos# esxcfg-module -g mlx4_en
 On ESXi:
rcli# vicfg-module.pl --server <ip> -g mlx4_en
2. Configure the module without the port configuration. Run:
esxcfg-module -s <config line from previous step> mlx4_en
3. Configure the port types if needed, using the connectx_port_config script.
4.2 Configuring VMware ESX Server Settings
VMware ESX Server settings can be configured using the vSphere Client. Once the InfiniBand
OFED driver is installed and configured, the administrator can make use of InfiniBand software
available on the VMware ESX Server machine. The InfiniBand package provides networking and
storage over InfiniBand. The following sub-sections describe their configuration.
This section includes instructions for
configuring various module parameters.
From ESX 4.1 use
esxcfg-module -i <module name> for viewing all the available module
parameters and default settings.
When using ESXi, use vMA or remote CLI vicfg-module.pl to
configure the module parameters in
a similar way to what is done in the Service Console (COS) for ESX.
4.2.1 Subnet Manager
The driver package requires InfiniBand Subnet Manager (SM) to run on the subnet. The driver
package does not include an SM.
If your fabric includes a managed switch/gateway, ple
ase refer to the vendor's user's guide to acti-
vate the built-in SM.
If your fabric does not include a managed switch/gateway
, an SM application should be installed
on at least one non-ESX Server machine in the subnet. You can download an InfiniBand SM such
as OpenSM from www.openfabrics.org under the Downloads section.
