Booting would not see the SAN disk but an explicit 'camcontrol rescan 1:0:4' would show the disk. My problem has to do with how cam code scans. If there is no device at lun 0 it does not probe the other luns. This should not be your problem since booting does pick them up. (and this is under 5.1, I'll reinstall 4.8 tomorrow not that I expect behaviour to change) What is the exact camcontrol command you use? -- tonym
