[OpenIndiana-discuss] Seagate 3000GB Drive only shows 746GB

[Rainer Heilke]

zpool create zname c4t0d0 succeeds, but this whacky partition table is 
what format is showing me. I did, at some point, see the EFI message you 
have, but I've been running in circles so much... When it did show this, 
it still said 746GB.
