it possible (albeit not advisable) to mirror LUNs that are NSD’s to another
storage array in another site basically for DR purposes? Once it’s
mirrored to a new cluster elsewhere what would be the step to get the filesystem
back up and running. I know that AFM-DR is meant for this but in
this case my client only has Standard edition and has mirroring software
purchased with the underlying disk array.</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri"> </span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">Is
