GlobalLB::Pool - How do I query GTM poolmember names?

Is this what you're looking for?

$poollist = (Get-F5.iControl).GlobalLBPool.get_list()
$memberlist = (Get-F5.iControl).GlobalLBPool.get_member($poollist)
$memcount = $memberlist.count
$i=0;while($i -le ($memcount-1)){$memberlist.Get($i).member;$i++}
