I just got a used Clariion and I have reconfigured it. I disocovered the issue i am having when i went to connect to my Windows 2008 Backup server using iSCSI. I have registered the host in the Navisphere software, Created the Raid Groups, Luns and Storage groups. Windows see's it but says "Disk Not Ready" when i go to initialize. It is a 6TB partition so i attempt to initialize it using GPT. From there I noticed my LUN was offline and when I try to bring it online it says "One or more of the selected LUNs can not be brought on line, contact your Service provider." Is this the reason why i can't initialize the LUN on my Windows server or is the issue something else? does anyone have EMC Clariion experience? Thanks All.
