Step 4: Identify unique hostnames for VxRail management components
Each of the VxRail management components you will deploy in the VxRail cluster will require you to assign an IP address, and also
assign a fully-qualified hostname. During initialization, each of these VxRail management components will be assigned a hostname
and IP address.
You need to make a decision on the naming format for the hostnames to be applied to the required VxRail management
components: each ESXi host, and VxRail Manager. If you decide to deploy the vCenter Server in the VxRail cluster, then that also
requires a hostname. In addition, if you decide to deploy Log Insight in the VxRail cluster, that needs a hostname as well.
You cannot easily change the hostnames and IP addresses of the VxRail management components after initial
implementation
Domain
Begin the process by selecting the domain you want to use for VxRail, and want to assign to the fully-qualified hostnames. Be aware
that DNS is a requirement for VxRail, so select a domain where the naming services can support that domain.
ESXi Hostnames
All ESXi hostnames in a VxRail cluster are defined by a naming scheme that comprises: an ESXi hostname prefix (an alphanumeric
string), a separator (“None” or a dash ”-“), an iterator (Alpha, Num X, or Num 0X), an offset
1
(empty or numeric), a suffix
2
(empty or
alphanumeric string with no .) and a domain. The Preview field shown during VxRail initialization is an example of the hostname of
1
Offset is available starting in VxRail Release 4.0.200. It is only applicable when the iterator is numeric.
2
Suffix is available starting in VxRail Release 4.0.200.
