Function Get-vCenterServer {
<#
.SYNOPSIS
Retrieves the vCenter Server details and connection object from SDDC Manager using either a workload domain
name or ESXi host FQDN.
.DESCRIPTION
The Get-vCenterServer retrieves the vCenter Server details and connection object from SDDC Manager using either
a workload domain name or ESXi host FQDN.
The cmdlet connects to the SDDC Manager using the -server, -user, and -password values.
- Validates that network connectivity and authentication is possible to SDDC Manager.
- Validates that network connectivity and authentication is possible to vCenter Server.
- Validates that the workload domain exists in the SDDC Manager inventory.
- Connects to vCenter Server and returns its details and connection in a single object.
.EXAMPLE
Get-vCenterServer -server sfo-vcf01.sfo.rainpole.io -user [email protected] -pass VMw@re1! -esxiFqdn sfo01-m01-esx01.sfo.rainpole.io
This example retrieves the vCenter Server details and connection object to which the ESXi host with The fully qualified domain name of sfo01-m01-esx01.sfo.rainpole.io belongs.
.EXAMPLE
Get-vCenterServer -server sfo-vcf01.sfo.rainpole.io -user [email protected] -pass VMw@re1! -domain sfo-m01
This example retrieves the vCenter Server details and connection object belonging to the domain sfo-m01.
.PARAMETER server

.SYNOPSIS
Restarts an ESXi host and poll for connection availability.
.DESCRIPTION
The Restart-EsxiHost cmdlet restarts an ESXi host and polls for connection availability.
Timeout value is in seconds.
.EXAMPLE
Restart-EsxiHost -esxiFqdn sfo01-m01-esx01.sfo.rainpole.io -user root -pass VMw@re1! -poll $true -timeout 1800 -pollInterval 30
This example restarts an ESXi host and polls the connection availability every 30 seconds. It will timeout after 1800 seconds.
.PARAMETER esxiFqdn
The fully qualified domain name of the ESXi host.
.PARAMETER user
The username to authenticate to the ESXi host.
.PARAMETER pass
The password to authenticate to the ESXi host.
.PARAMETER poll
Poll for connection availability after restarting the ESXi host. Default is true.
.PARAMETER timeout
The timeout value in seconds. Default is 1800 seconds.
.PARAMETER pollInterval
The poll interval in seconds. Default is 30 seconds.
