Function Connect-Unity { <# .SYNOPSIS Connects to an EMC Unity Array .DESCRIPTION Connects to an EMC Unity Array. This cmdlet starts a new session with an EMC Unity Array using the specified parameters. When you attempt to connect to an array, the array checks for valid certificates. To avoid this use the -TrusAllCerts param. You can have more than one connection to the same array. To disconnect from an array, you need to close all active connections to this server using the Disconnect-Unity cmdlet. Every new connection is stored in the $global:DefaultUnitySession array. .NOTES Written by Erwan Quelin under MIT licence - https://github.com/equelin/Unity-Powershell/blob/master/LICENSE .LINK https://github.com/equelin/Unity-Powershell .PARAMETER Session Specifies an UnitySession Object. .PARAMETER Username Specifies the username. .PARAMETER Password Specifies the password.
