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
