To set up vDS, see the following VMware Knowledge Base articles. Pynfs can be detected by running the following command on any Controller VM. Else, use static binding for port groups where the Controller VM external network is connected. If pynfs is used, dvSwitch port group may need to be set to ephemeral. Assign the other interface to a port group that can communicate with the other hosts and Controller VMs over their public addresses. Assign one interface to the svm-isci-pg at all times. The Controller VM has two interfaces assigned to it. This is a common configuration and can disrupt the host communication with the Controller VM on the vSwitchNutanix network. If you are using the vmkernel port migration wizard for dvSwitch, ensure that vmk-svm-iscsi-pg is not automatically selected. On the Manage physical adapters page, you can add or. On the Select hosts page, under Member Hosts, select from the hosts that are associated with the distributed switch. On the Select task page, select Manage host networking and click Next. See the VMWare documentation for details. On the vSphere Client Home page, click Networking and navigate to the distributed switch. This condition is not unique to the Nutanix configurations. For example, if all the available uplinks are moved to a dvSwitch that is not configured properly, the host becomes unavailable on the network. The external management vmk address or the vmk address in the same public subnet as the Controller VM is needed for Nutanix autopath functionality.Įnsure that there are enough available uplinks to keep the host's vmk address during the dvSwitch migration. The datastore may become unavailable on the host being migrated because the external management vmk address may be unavailable during the migration. Migrate all VMs except the Controller VM when you are migrating that particular host to dvSwitch. A very common misconception is that VDS is a single switch that spans over multiple ESXi hosts.
In general, one Controller VM can be off the network at a given time while the others continue to provide access to the datastore. A vSphere distributed switch (VDS) was primarily built to reduce the administrative overhead involved in maintaining the network configuration in a large environment.
This ensures that the cluster services running on all Controller VMs continue to function during the migration. After migrating the host to the dvSwitch, confirm that the Controller VM can communicate with all other Controller VMs in the cluster. Only migrate one host to a dvSwitch at a time. Migrating the vSwitchNutanix to the vDS causes issues with upgrade, and also controller VM data path communication. It should remain as a standard vSwitch and should not be migrated over to the vDS. Keep the vSwitchNutanix, the vmkernel port (vmk-iscsi-pg), and the Nutanix Controller VM's virtual machine port group (svm-iscsi-pg) configuration intact. Nutanix recommendations for implementation Nutanix cluster works with the vDS and you can use the following guidelines and recommendations to configure the vmk and VM interfaces to be part of the vDS.
