Create the following constructs in vCenter if they do not already exist:
Data center.
Cluster within the created data center with ESXi hosts added. CSP High Availability (HA) is the default. HA requires a minimum of three ESXi hosts, and VMware HA must be enabled. Consult your solution documentation to determine if additional hosts are required.
Cluster with at least one datastore added. The VMware cluster used for Common Services must have access to a datastore. All ESXi hosts within the VMware cluster as well as the Cluster Control Manager and Common Services cluster node virtual machines must have access to the datastore.
Additionally, the datastore used for the Common Services cluster must have hosts that are associated only to the cluster where the product is being deployed. It must be accessible from the Cluster Control Manager and from the Common Services cluster nodes. If the datastore is made up of one or more host resources, these hosts must have access to the VMware cluster where Cluster Control Manager and Common Services cluster nodes are being deployed.
Note the following:
Local datastores and datastore clusters are not supported.
Solution deployment in VMware vApp is not supported.
Suspending and resuming a virtual machine in VMware is not supported.
You must have a VMware network switch. You can use a vSphere standard or distributed switch.
If you are using a vSphere standard switch, each ESXi host within the cluster must use the same name for the standard switch.
If you are using a distributed switch, each ESXi host must have access to the distributed switch.
The network used for the deployment should be under the datacenter.
Using VMware Distributed Resource Scheduler (DRS) is optional.
For HA CSP deployments, Avaya recommends to enable VMware DRS at the cluster level and set it to fully automatic. Use a conservative migration threshold when DRS is set to partially automatic or fully automatic.
If VMware DRS is not enabled, then the High Availability Audit feature must be disabled. When prompted to configure the HA audit during installation, decline the audit if DRS is disabled.
For information about hot migration (vMotion) support, see your solution documentation.
Enable the NTP service and synchronize the time on all ESXi hosts in vCenter with an external time source. Configure Cluster Control Manager and Common Services nodes with the same external time synchronization source.
Tip:
To find the time stratum, run chronyd -q -t 1 "server <ServerIP> iburst maxsamples 1", where <ServerIP> is the IP address of your NTP server.
