Your array should keep on using the same HW ID, since you would rather "grow" the LUN, than re-create a bigger one. Many months ago I tried to get Solaris to recognize a bigger LUN after the initial branding... but I couldn't get it to work correctly. I do know that there has been work done in this area of "auto LUN resizing" ... but I don't know what the status is. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
