Did you try remounting the target (on initiator side)?
Also, did you inspect the LUNs (as "disks") formatting and
partitioning layout?

I believe that remounting the target should allow the full
LUN size to be seen. However the old partition table remains
in place, so you'd have to enlarge that (fdisk, parted). Then
in the increased partition you can increase the filesystem
with its tools - for ZFS this would mean increasing Solaris
slices first, then expanding the pool (possibly with explicit
"zpool attach -e ...").
