Hi All,

we've got 3 LUNs assigned to the same host with the same RAID group
LUN1 = 400GB
LUN2 = 100GB
LUN3 = 130GB

we want to change LUN1 capacity to 630GB from LUN2 and LUN3, my question are:
can the host detect the new 630GB without being restarted?
what happen to the data inside the LUN? , will the disk need to be formatted when the 400GB changed into 630GB?
