You should be able to carve up the array that way. I think you're mixing your terminology there. gpt isn't a partition type, it's a disklabel. There's only one per disk (obviously), no matter how many partitions are on the disk. What some array controllers can do is carve a single array into multiple volumes (usually each presented on their own LUN). Then you could carve the one array into a small boot volume (with an msdos disklabel and multiple partitions) on one LUN and the rest in a large data bolume (with a gpt disklabel) on the other LUN. -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF
