Displaying fnic_max_qdepth Parameter Value

The current and postconfiguration value of the fnic_max_qdepth parameter can be displayed using the following commands .

RHEL 6 .x / SLES11 / XS

1 . To display the current fnic_max_qdepth, run the following command:

# cat /sys/module/parameters/fnic_max_qdepth

2 . To display the current fnic_max_qdepth on a per-LUN basis, which is relevant if the value was changed using the run-time

configuration for newly discovered LUNs, run the following command at the command-line interface (CLI) (install lsscsi if

not already installed):

# lsscsi –l

ESX 5 .x

1 . From the ESX CLI, run the following command (the fnic_max_qdepth parameter will not be listed until it has been explicitly

set per the configuration instructions below):

# cat /etc/vmware/esx .conf |grep fnic

Results:

/vmkernel/module/fnic/options = fnic_max_qdepth=128

2 . From the ESX CLI, run the following esxcli command (the fnic_max_qdepth value will be empty until the fnic_max_qdepth

parameter has been explicitly set per the configuration instructions below):

# esxcli system module parameters list –m fnic
