Virtual server become gray status.

Hello davidy2001 , 
               this gray mark related to " manual disable or manual forced offline " to Pool members or Virtual address of this virtual server , I will explain the 2 scenarios : 
Firstly : 
> let we say that virual server is the parent , and pool members are its children and they are combined in one pool. 
- when you manually disable pool members , their parent or Virtual server become gray. 
- gray virtual server could not handle traffic. 

To solve this issue : 

> go to the Pool that assigned to " New-virtual-server" >>>> open members tab >>> you will find your pool members such this snap shot : 

> put the check mark beside the Black circle and click enable , after tat you should see this pool member become available and marked with Green circle. 
> After enabling your pool member , the " New-virtual-server" will be marked with green circle as well and can handle traffic without issues. 

Secondly : 

> open ( local traffic >>> choose virtual servers list >>> click Virtual address list TAB ) , you will find it as below snap shot : 

> mark the check box beside the black circle , and click enabe , it will become available with green circle. 
> after that you will find its relevant virtual server become available as well and can process traffic.
