What do you see in Format Inquire (or Format Current) and in Format Verify? Any more information on "Solaris cannot use them" would be helpful. What kind of LUNs (OPEN-E, OPEN-*, something else? - What type of disk subsystem are you using and do you share SAN ports (targets) with non-solaris systems? Do you have any form of LUN-masking in place? What Type of Partition table? In certain situations EFI labels are needed - I'm not an expert on these and have not figured out the exact conditions yet, but I seem to recall that EFI labels are required for disks bigger than 1 TB (might have been 2 TB). I suspect 32-bit vs 64-bit kernel also affects the largest LUN size usable. Cheers, _hartz
