 2) nas_pool -extend of system_defined pool in order to use the new luns   there is no need to manually extend a system pool - when the Celerra discovers new LUNs they become automatically eligable for the system pool that matches their profile and they are "pulled in" on demand  for the rest of the procedure - I would suggest to look at using multiple checkpoints and differential copies to minimize the downtime. Or - if you have a the license - at using full-blown Replicator, which does this automatically  Rainer
Hello, probably this is an already threaten thread....  I've a NS480 box with NAS 5.6.49-3 version.  At the moment, my clar5_performance pool is composed of 4x 4+1 450 GB disks in RAID 5 configuration (6,3 TB of datas).  In one month, I'll receive brand new 600 GB disks (probably 20), and I want to migrate on them all of my cifs file systems. (consider that I'll configure all of disks in RAID 5 configuration [4+1 disks and creating 2x luns per storage group... ].  How should I do them? with Clariion Lun migration? With File system copy?  Can I do it without service outage?  Thanks for any answer.  PS: I'm using AVM  Riccardo Barone
