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
Results:
Name Type Value Description
