[OpenIndiana-discuss] How can one test in situ, and under OI, the physical blocksize a SATA disk actually reports??

[Reginald Beardsley]

FWIW 

This is how and shows what an ST2000DM001 properly configured using sd.conf reports:


oi%rhb {2} echo "::sd_state" | mdb -k | egrep '^un|blocksize'
un 0: ffffff0140ddfd00
    un_sys_blocksize = 0x200
    un_tgt_blocksize = 0x200
    un_phy_blocksize = 0x1000
    un_f_tgt_blocksize_is_valid = 1

0x200 = 512 bytes
0x1000 = 4096 bytes

Have Fun!
