Here is the workflow for upgrading the nfnic driver: The host is put into maintenance mode (either from the CLI or esxcli system maintenanceMode set -enable true The nfnic folder was copied to a datastore in the VMware environment that each of the hosts were connected to, in this case an ISO ls /vmfs/volumes/sn1-m20-c12-25-ISO-Repository/VMware/Drivers/nfnic_ESXi_6.7U2/ TheР’В nfnic package can also be downloadedР’В from VMware.

No of outstanding IOs with competing worlds: 32 Confirm what version is currently running on the esxcli software vib list |grep nfnic.This means that this driver will need to be manually installed until a Cisco image or an image from VMware are released with an updated nfnic driver. This is not the default nfnic driver for ESXi 6.7 U2 and under. This could also affect any high workload and IOPs VMs that need higher queue depths across the board.Р”В¬isco released an updated version of the nfnic driver in 4.0.0.35Р’В to adjust 'lun_queue_depth_per_path'. This has primarily been an issue when using vSphere Virtual Volumes as the default device queue depth for a Protocol Endpoint should be 128. This would apply to device backings for VMFS Datastores, RDMs and Protocol Endpoints. With the default queue depth with the nfnic driverР’В set to 32, that in turn limits all Maximum Device Queue Depth and DSRNOР’В (Disk Schedule Number Requests Outstanding) to 32. This KB will cover updating the nfnic driver, adjusting the nfnic queue depth and device queue depth.Р”В¬isco has a published Bug outlining the issue, CSCvo09082, which can be referred to as needed.

Cisco released an updated version of the nfnic driver (4.0.0.28+) with a configurable module parameter, 'lun_queue_depth_per_path'.

With this update the default queue depth with the nfnic driver is set to 32 and initially there was not a module parameter to adjust the nfnic queue depth. With ESXi 6.7 the Cisco fnic driver was replaced with the Cisco nfnic driver for UCS Blades running ESXi.
