CSCwm26689

Upgrading the networking adapter nenic driver version to 5.13.24.2 or using this specific driver version on a newly installed Windows Server OS result in a BSOD followed by a host reboot.

If a lower nenic driver version is used instead of the version 5.13.24.2, then the BSOD does not appear.

4.3(2b), 4.3(4a), 4.3(5a)

CSCvy16861

In a Windows Hyper-V environment the VMQ feature is enabled. Event ID 113 is logged in the system event viewer when VMs are powered ON.

It has been determined that this issue does not have any functional or performance impact on the functioning of the VMQ feature. This issue will be investigated in a future release.

4.2(0.193)B

CSCvv76888

On a Cisco VIC 1300 Series adapters, using neNIC Driver version 4.3.0.6 and a 1300 Series adapter with a VMQ policy, a yellow bang appears when configured with a VMQ sub-vNIC value of 10 or less.

When a VMQ policy is created, ensure that there are at least 32 interrupts, even though the number of VMQs in the policy is lower. This will enable the driver to load and function correctly.

4.1(2.13)B

CSCvx81384

In a UCS Manager service profile where vHBAs are assigned with an FC adapter policy that has more than one I/O Queues, BSOD will be observed after loading the fNIC driver on Windows 2019. The issue is observed on VIC 1400 Series adapters on SAN and Local boot.The server showed BSOD or the below error:

Stop code: PAGE FAULT IN NONPAGED AREA

Modify the FC adapter policy and set the I/O Queues to 1.

CSCvr63930

On ESXi, a Cisco UCS B-series blade server and Cisco UCS C-series rack server with a a Cisco VIC 1440, VIC 1480,,1455, 1457, or 1467 adapter, the port link speed output is not updating after an uplink is Down /Up.

  • Reboot the ESXi host to get the correct port speed reporting.

  • If a new UIF link needs to be added or deleted to the existing system, a reboot is required to reflect the correct speed in ESXi.

CSCvt66474

On Cisco VIC 1400 Series adapters, the neNIC driver for Windows 2019 can be installed on Windows 2016 and the Windows 2016 driver can be installed on Windows 2019. However, this is an unsupported configuration.

If the Windows 2019 neNIC driver is installed on Windows 2016, RDMA is not supported.

If the Windows 2016 neNIC driver is installed on Windows 2019, the RDMA feature that is supposed to be enabled on Windows 2019 will be disabled.

The driver binaries for WS2016 and WS2019 are in folders that are named accordingly. Install the right binary on the platform that is being built or upgraded.

4.2(1.151)A

Behavior Changes and Known Limitations

Virtual Machine Multi Queue (14xx and 15xxx vNICs)

Disabling VMMQ state for vport is not taking effect.

Workaround

Use the power shell command to disable and assign queue to 1.

#Get-VMNetworkAdapter -vmname * | Set-VMNetworkAdapter -VmmqEnabled $false -VmmqQueuePairs 1

Cisco UCS VIC adapters with Cisco UCS VIC firmware version 4.1(2b) and later do not support Third Party Transceivers

Cisco UCS VIC adapters with Cisco UCS VIC firmware version 4.1(2b) and later do not support third party transceivers.

Use Cisco qualified transceivers or cabling for the physical links after 4.1(2b).

When LUNs per Target is set to more than 1024 in FC adapter policy of vHBAs, but the actual value deployed in FC vNIC is capped to 1024.

In Cisco UCS Manager 4.2(3c) release or later, when LUNs Per Target field is set to more than 1024 in FC adapter policy of vHBAs of Service Profile, the actual value deployed in FC vNIC is capped to 1024.

This issue occurs because the firmware version on the VIC adapter is old and does not support more than 1024 value for LUNs Per Target.

RHEL 8.7 boots to emergency shell when LUNs Per Target is set to greater than 1024

If LUNs Per Target is set to greater than 1024 with multiple paths running RHEL 8.7, the OS takes a long time to scan all the paths. Eventually, the scan fails and the OS boots to the emergency shell.

Reduce the number of LUNs Per Target (paths) to be scanned by the OS.

Q-in-Q Forwarding (14xx and 15xxx VNICs)

For double tagged frames (1Q + 1Q) generated by the host are sent out by the VICs, you must configure the following commands on the Linux host.

  1. Disable VLAN TX offload on the 14xx or 15xxx VNICs that need to transmit out double tagged (1Q + 1Q) frames.

    Perform this from the host and enter the following ethtool command:

    ethtool -K <interface_name> txvlan off

  2. To verify that the VLAN TX offload feature has been turned off, enter the following command:

    ethtool -k <interface_name> | grep tx-vlan-offload

Windows : Default adapter policy win-HPN-SMBd to be changed to 512+ for large logical processors value

Modify the interrupt value to 514 and re-deploy the updated setting.

Support for Physical NIC Mode

Beginning from release 4.2(3b), physical NIC mode is supported completely and the term Experimental is removed from Physical NIC mode for Cisco UCS C-Series Rack Servers.

Physical NIC mode is not supported in trunk mode.

Link Speed on ESXCLI is not updated at Runtime after Link Down/UP

This issue occurs when VMware API is not updating the Link status to Driver.

To avoid this, run the following command at FI or Up Link switch:

sh interface port-channel (uplink Po)

vNIC MTU Configuration

MTU on VIC 1400 Series adapters in Windows is now derived from the Jumbo Packet advanced property rather than from the UCS configuration

For VIC 14xx adapters, you can change the MTU size of the vNIC from the host interface settings. The new value must be equal to or less than the MTU specified in the associated QoS system class. If this MTU value exceeds the MTU value in the QoS system class, packets could be dropped during data transmission.

RDMA Limitations

  • The VIC 1400 Series Windows drivers on Blade and Rack servers do not support more than 2 RDMA engines per adaptor. Currently, Windows can only support RDMA on 4 VPorts on each RDMA Engine.

  • RoCE version 1 is not supported with any fourth generation Cisco UCS VIC 1400 Series adapters.

  • UCS Manager does not support fabric failover for vNICs with RoCEv2 enabled.

  • RoCEv2 cannot be used on the same vNIC interface as NVGRE, NetFlow, and VMQ features.

  • RoCEv2 cannot be used with usNIC.

  • RoCEv2 cannot be used with GENEVE offload.

Configuration Fails When 16 vHBAs are Configured with Maximum I/O Queues

Cisco UCS Manager supports a maximum of 64 I/O Queues for each vHBA. However, when you configure 16 vHBAs, the maximum number of I/O Queues supported for each vHBA becomes 59. In Cisco UCS Manager Release 4.0(2), if you try to configure 16 vHBAs with more than 59 I/O queues per vHBA, the configuration fails.

VM-FEX

ESX VM-FEX and Windows VM-FEX are no longer supported.

Auto-negotiation

When a palo_get_an_status mptool command is issued, it now shows that auto-negotiation is turned on all the time.

Link Training

The Link Training option is not configurable from CIMC for VIC 13xx adapters.

INTx Interrupt Mode

INTx interrupt mode is not supported with the ESX nenic driver and nfnic driver.

INTx interrupt mode is not supported with Windows nenic and fnic drivers.

INTx interrupt mode is not supported with Linux enic and fnic drivers.

FC-NVMe Failover

To protect against host and network failures, you must zone multiple initiators to both of the active controller ports. Passive paths will only become active if controller fails, and will not initiate a port flap. On operating systems based on older kernels that do not support ANA, dm multi-path will not handle the passive paths correctly and could send IOs to a passive path. These IO operations will fail.

FC-NVMe Namespaces

Starting with RHEL 8.5 nvme-cli version 1.14, the nvme list command will not display fc-nvme namespaces. Use nvme-cli from RHEL 8.4 or a nvme-cli version of 1.15 or later to view fc-nvme namespaces.

FC-NVMe ESX Configurations

VIC 15000 and 1400 Series adapters running ESXi currently only support a maximum FC-NVMe namespace block size 512B, while some vendors use a default 4KB block size for ESXi 7.0. The target FC-NVMe namespace block must therefore be specifically configured to 512B. Under Storage go to NVME and change the Block Size in NVMe from 4KB to 512B.

Configuration changes are also required to avoid a decrease in I/O throughput and/or BUS BUSY errors, caused by a mismatch between FC-NVMe Target controller Queue-depth and VM Device Queue-depth. To avoid this, run the following command to display all controllers discovered from ESXi Host:

# Esxcli nvme controller list

Check the list of controller queues and queue size for the controllers:

# vsish -e get /vmkModules/vmknvme/controllers/controller number/info

All Controllers on the same target will support same queue size, for exaple:

Number of Queues:4
Queue Size:32

To tune the VMs, change the queue_depth of all NVMe devices on the VMs to match the controller Queue Size. For example, if you are running a RHE VM, enter the command:

# Echo 32 > /sys/block/sdb/ device/queue_depth

Verify that the queue_depth was set to 32 by running the command:

# cat /sys/block/sdb/ device/queue_depth


Note

This change is not persistent after reboot.

Note

For additional driver configuration, it may be necessary to set the Adapter Policy to FCNVMeInitiator to create a FC-NVMe Adapter.

Adapter Policy can be found under Server > Service Profile>Policies> Adapter Policies Create FC Adapter Policy>

Adapter Policy can be found under Server > Service Profile> Storage> Modify vHBAs

Enabling FC-NVMe with ANA on ESXi 7.0

In ESXi 7.0, ANA is not enabled for FC-NVMe. This can cause failure of the Target side Path failover.

For a procedure to enable ANA, go to the following URL: https://docs.netapp.com/us-en/ontap-sanhost/nvme_esxi_7.html#validating-nvmefc
