not much to do on the NS-480 expect creating the new LUNs.  For the merging part it depends on your "old HP server" config and OS you need some OS skills there or involve/hire someone who has them
Hi All,  I have a NS-480 , and has 120*8Gb Luns are assigned to old HP servers I need to migrate to Unity ! I cant afford 120 LUN iD's for only960 gig !   here is the question   1 ) is there any way I could merge all this LUNS to a single LUN .   2 ) Can I create a destination LUN of 960 GB and do the migration for all the LUNS at a single destination ...will this work ?    please note that these are old servers and We are about to De-commission those , how ever , we are trying to save this Read Only 960gig  Thanks
