I have a VNX5300.  Currently, all of our disk space is being consumed for CIFS file storage on a mix of NL-SAS and SAS drives.  We recently purchased and added 5 additional NL-SAS drives, which we'd like to use for additional file storage space.  We also need to configure iSCSI for VMWare images - how can I reallocate the file storage space to use the new NL-SAS drive, and repurpose the SAS drives from file storage for iSCSI?  Is there a way to do this without recreating the entire Storage Pool / File System?

Thanks,
