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

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

module name.

# esxcli system module list | grep lpfc

lpfc820 true true

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

2 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

4 5

3 Check the default value for the Converged Network Adapter card.

Specify the module name for the Converged Network Adapter card that you recorded in Step 1 and

check the default value.

# esxcli system module parameters list -m lpfc820 | grep lpfc[0-1]_lun_queue_depth

lpfc0_lun_queue_depth int Max number of FCP commands we can queue to a specific LUN

lpfc1_lun_queue_depth int Max number of FCP commands we can queue to a specific LUN

[0-1] indicates that the number of ports is two.

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

Driver parameter Setting value

lpfcX_lun_queue_depth Arbitrary (*1)

(Up to 512 for each FCoE port of the ETERNUS DX)

*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.
