Are you sure this is an 4k sector drive? The drives manual doesn''t
mention anything about 4k sectors or "advanced format".

hi there,

i cannot figure out how to make openindiana recognize the seagate ES.2 SAS 3TB
(ST33000650SS) as a 4k advanced sector drive.

in /kernel/drv/sd.conf i added the info for the drive:

	sd-config-list = "SEAGATE ST33000650SS",
"physical-block-size:4096";

to update the settings without a reboot

	update_drv -vf sd

destroy the pool and recreate it with

	zpool create test ?

testing with the command stills reports 512k blocks

	zdb test | grep ashift
		 ashift: 9


the funny thing is that the consumer SATA Drive Baracuda ST3000DM001 gets
recognized as a 4k drive perfectly out to the box.
