Once we have configured the IP address of both vmk0 and vmk1, we are done with the procedure of configure vSAN witness appliance networking. If both vmk0 and vmk1 are configured on the same range, a multihoming condition will occur and vSAN traffic will flow from vmk0, rather than vmk1. This is because Management traffic and vSAN traffic use the default TCP/IP stack. Validate that “vSAN” is selected under the enabled services.Ĭlick on next and assign the IP address for the Witnesspg vmkernel interface. The vmk1 interface cannot be configured with an IP address on the same range as that of vmk0.
Select VMkernel adapters > vmk1 to view the properties of the “witnessPg”. we need to configure the IP address for the VMkernel interface If there is no DHCP server on the vSAN network (which is likely), then the VMkernel adapter will not have a valid IP address. This VMkernel port to be used for vSAN traffic is visible. The Witness appliance has a port group pre-defined called witnessPg. The next step is to configure the vSAN network correctly on the vSAN Witness To configure, Select the vSAN witness appliance, navigate to Configure > Networking > Virtual switches as shown below. We have configured the management network of the vSAN witness appliance. It has a light blue shading, to differentiate it from standard ESXi hosts.Ĭonfiguring vSAN Witness Appliance Networking you can see the difference in the appearance of the vSAN Witness Appliance ESXi instance in the vCenter inventory. VSAN witness appliance is added into vCenter inventory. Click Next.įollow other wizard instructions as same as adding ESXi hosts into vCenter inventory.
The witness switch password#
Specify the root username and password to add the vSAN witness appliance to vCenter server inventory. In this example, the vCenter server is managing multiple data centers, so we are adding the host to the witness data center (Witness-DC). The first step is to provide the name of the Witness. However, there are some interesting items to highlight during the process. There is no difference in adding the vSAN Witness Appliance ESXi instance to the vCenter server when compared to adding physical ESXi hosts. We need to add the witness appliance (ESXi) into the vCenter Server. Once the management network is configured for the vSAN witness appliance. The FQDN(fully qualified domain name)of the host should also be added at this point. A primary DNS server should be added and an optional alternate DNS server can also be added. Specify the IP address, subnet mask, and gateway for the management network. There will be two network adapters, each corresponding to the network adapters on the virtual machine. Press F2 to customize the system and login with the root credentials Open the console of the vSAN witness appliance virtual machine. Open the console of the vSAN Witness Appliance to configure networking information, such as IP address and DNS, for the management network. Log in to the vCenter server where the witness appliance is deployed. Configure vSAN Witness Appliance Management Network We need to configure the networking for the Witness host via DCUI which is very familiar for all of us. Its only purpose is to serve as a vSAN witness. Unlike a general purpose ESXi host, the witness appliance does not run virtual machines.
The witness switch license#
You don’t need to provide a license for ESXi (vSAN witness appliance). The vSAN virtual appliance is nothing but the virtual machine running ESXi host.
The witness switch how to#
In this article, Let’s understand how to configure vSAN witness appliance virtual machine. In my previous post, we have discussed how to deploy virtual vSAN Witness appliance in the vSphere cluster. Keeping a dedicated a physical ESXi host as witness host will need a license, Power consumption, and hardware maintenance and data center space, etc as all condition applies to run a workload in the physical server as compared to virtualization.
vSAN Witness can be run in both physical and virtual appliance. VMware vSAN Stretched Cluster supports the use of a vSAN Witness Appliance as the Witness host.
