On HPE Platforms running VMware ESXi 6.0 (or later), and configured with more than six network adapters but that do not exceed the network hardware maximums specified by VMware; some ports of the network adapters may not be available. Note: To verify that the system has not exceeded the ESXi Host Maximums (Networking Maximums) for the number of network ports, refer to the following URL: VMware Configuration Maximums Example In the following example configuration, one HPE FlexFabric 10Gb 4-port FLR-T 57840S Adapter and six HPE Ethernet 10Gb 2-port BASE-T BCM57416 Adapters are configured on the HPE platform. If the command "esxcli network nic list" is executed, only two ports on the HPE FlexFabric 10Gb 4-port FLR-T 57840S Adapter will be displayed. When this command is executed, all four ports should be displayed, but only two ports (vmnic4 and vmnic5) are available: esxcli network nic list Name PCI Device Driver Admin Status Link Status Speed Duplex MAC Address MTU Description ------- ------------ ------- ------------ ----------- ----- ------ ----------------- ---- ----------- vmnic0 0000:02:00.0 ntg3 Up Up 1000 Full 94:40:c9:1f:9f:76 1500 Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet vmnic1 0000:02:00.1 ntg3 Up Up 1000 Full 94:40:c9:1f:9f:77 1500 Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet vmnic10 0000:13:00.0 bnxtnet Up Up 1000 Full 9c:dc:71:b3:df:10 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic11 0000:13:00.1 bnxtnet Up Up 1000 Full 9c:dc:71:b3:df:18 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic12 0000:88:00.0 bnxtnet Up Up 1000 Full 9c:dc:71:bb:24:c0 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic13 0000:88:00.1 bnxtnet Up Up 1000 Full 9c:dc:71:bb:24:c8 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic14 0000:b0:00.0 bnxtnet Up Up 1000 Full 9c:dc:71:b3:54:70 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic15 0000:b0:00.1 bnxtnet Up Up 1000 Full 9c:dc:71:b3:54:78 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic16 0000:d8:00.0 bnxtnet Up Up 1000 Full f4:03:43:ea:aa:70 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic17 0000:d8:00.1 bnxtnet Up Up 1000 Full f4:03:43:ea:aa:78 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic18 0000:d9:00.0 bnxtnet Up Up 1000 Full 9c:dc:71:b3:df:50 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic19 0000:d9:00.1 bnxtnet Up Up 1000 Full 9c:dc:71:b3:df:58 1500 Broadcom BCM57416 NetXtreme-E 10GBASE-T RDMA Ethernet Controller vmnic2 0000:02:00.2 ntg3 Up Up 1000 Full 94:40:c9:1f:9f:78 1500 Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet vmnic3 0000:02:00.3 ntg3 Up Up 1000 Full 94:40:c9:1f:9f:79 1500 Broadcom Corporation NetXtreme BCM5719 Gigabit Ethernet vmnic4 0000:5d:00.0 qfle3 Up Up 1000 Full 9c:dc:71:ca:3e:40 1500 QLogic Inc.

This inactive ports issue occurs due to a vmkernel condition limiting the number of interrupts available for driver modules. In this case, the qfle3 driver module does not bond to all the configured network adapters. When PCI Passthrough devices request many interrupts to be allocated, it is possible that this limit has been reached, which causes the issue. For additional information, refer to the following VMware Knowledge Base Article: Increasing maxIntrCookies if default limit is reached in ESXi 6.x (78182) To determine if this issue is impacting the system, look into "/var/run/log/vmkernel.log," to find messages similar to the following: WARNING: IntrCookie: 1421: Unable to find a free interrupt number; see https://kb.vmware.com/s/article/78182
Any HPE Platform running VMware ESXi 6.0 (or later) and configured with more than six network adapters but that do not exceed the network hardware maximums specified by VMware. Important information: This issue was originally reported on an HPE ProLiant DL380 Gen10 server running VMware ESXi 7.0, and configured with one HPE Ethernet 1Gb 4-port 331i Adapter, one HPE FlexFabric 10Gb 4-port FLR-T 57840S Adapter (764302-B21) and six HPE Ethernet 10Gb 2-port BASE-T BCM57416 Adapter (813661-B21); but this condition is not limited to HPE products only, and other configurations may be impacted. Note: The network adapter(s) in this document are affected by a naming standard change for HPE products to help customers quickly and easily identify the specific vendor and model while configuring HPE platforms. For more information about the name changes and for identification purposes, refer to the following Customer Notice: HPE Network Adapters - Product Renaming Framework And Plan For HPE Network Adapters
To free up additional resources for driver modules to bond to the network adapter, perform the following steps: Execute the following command: esxcli system settings kernel set -s maxIntrCookies -v 4096 Reboot the server, and the impacted network ports should be available.
