Setting Up the Converged Network Adapter Cards

1.2.4.3

For VMware vSphere 4

Record the module name for the Converged Network Adapter card that is loaded into VMware ESX.

The underlined portion indicates the loaded module name. In the following example, "lpfc820" is the

module name.

# vmkload_mod -l | grep lpfc*

lpfc820

Module names may vary depending on the Converged Network Adapter card that is used.

Check the default value for the Converged Network Adapter card.

Specify the module name for the Converged Network Adapter card that you recorded in

check the default value.

# esxcfg-module -g lpfc820

lpfc820 enabled = 1 options = ' '

Check that no value appears in the underlined portion.

Check the number of ports on the Converged Network Adapter card.

The SCSI Host numbers of the Converged Network Adapter card that are displayed represent the number

of ports.

In the following example, the number of ports is "two" since "4" and "5" (two underlined portions) are

displayed as the SCSI Host numbers of the Converged Network Adapter card.

# ls /proc/scsi/lpfc820

Change the setting values of the parameter for the Converged Network Adapter card driver.

Driver parameter

lpfcX_lun_queue_depth

*1: Recommended value = 512 ¸ (number of FCoE ports that are connected to a single CA port) ¸

number of LUNs

(Round the result down)

Use the value of "8" if the actual result is lower.

Use the following command to change the setting values when the driver parameter name is

"lpfcX_lun_queue_depth", the number of I/Os is "8", the module name is "lpfc820", and the number of

ports is "2".

# esxcfg-module -s "lpfc0_lun_queue_depth=8 lpfc1_lun_queue_depth=8" lpfc820

Input the number of I/Os ("8" in this example) for each driver parameter setting.
