did you actually create new storage group in Navisphere ? What you need to do is to create a raid-5 group (4+1), create two LUNs (one on SPA and one on SPB, same size but not to exceed 2TB) and add them to the existing Celerra storage group.Rescan each datamover, after that you can create user-defined pools and add those LUNs there. See document "Managing Celerra Volumes and File Systems Manually"
 I need to add a set of 5 new 1TB SATA drives to my Celerra as a new RAID5 group and be able to create new filesystems & iSCSI targets that get directed to that Raid5 array distinct and separate from the rest of my iSCSI targets/filesystems.  I've followed the instructions here ([URL] as closely as they can be matched to my Celerra NS20, and bound the newly created LUNS to a new 'Storage Group' under Navisphere Manager.  When I go into Celerra Manager, there are still only two "Storage Pools" available to choose from, the original two as was installed by EMC personell when the system was brand new. Those are "clar_r5_performance" for the drive chassis filled with FC disks, and "clarata_archive" for the drive chassis full of existing SATA drives. The system was installed with a third, empty drive chassis, into which I've added the 5 new SATA drives.  I've already got many iSCSI targets / filesystems already defined and in production use on the "clarata_archive" referenced set of SATA drives, which are connected to several servers already.  I'm adding a brand new document imaging server to my network, and I wish for its iSCSI targets/filesystems to reside strictly on the new set of 5 disks defined as a RAID5 array, distinct and separate from that "clarata_archive" massive blob of SATA storage, so I believe I need to make a new "storage pool" which shall reference that new array, but there doesn't seem to be any clear way of doing that. The "Pools" folder under the "Storage" folder within Celerra Manager is grayed out and does nothing.   How can I accomplish what I need here?
How do I add new SATA-II disks as a new storage group / storage pool?
