Possibly not the right list, but the only appropriate one I knew about. I have a Solaris box (just reinstalled to Sol 10 606) with a 3.19TB device hanging off it, attatched by fibre. Solaris refuses to see this device except as a 1.19 TB device. Documentation that I have found (http://docs.sun.com/app/docs/doc/817-5093/6mkisoq1k?a=view#disksconcepts-17) Suggests that this will not work with the ssd or sd drives. Is this really the case? If that isn''t supported, what is? Before you ask, yes, we can divide the device up into LUNs and glue it back together again in Solaris, but that is a stupid solution, and if I were to buy a top of the line Sun storage solution with 330TB I wouldn''t be pleased if I had to glue 165 virtual disks back together because of this.

Well if in fact sd/ssd with EFI labels still have limit to 2TB than
create SMI label with one slice representing whole disk and then put
zfs on that slice. Eventually manually turn on write cache then.

Eventually manually turn on write cache then.Well, in fact it turned out that the firmware on the device needed upgrading to support the appropriate SCSI extensions. The documentation is still wrong in that it suggests that the ssd/sd driver shouldn''t work with >2TB, but I am happy, so no problem.

Hi Julian, Can you send me the documentation pointer that says 2 TB isn''t supported on the Solaris 10 6/06 release? The 2 TB limit was lifted in the Solaris 10 1/06 release, as described here: http://docs.sun.com/app/docs/doc/817-5093/6mkisoq1j?a=view#ftzen Thanks, Cindy J.P.
