>Description:
Fails to boot FreeBSD 8.1-PRERELEASE from RAID volume under hptiop(4) (HighPoint RocketRAID 3xxx/4xxx RAID controller).
RAID controller seems to be detected normally as hptiop(4). However, RAID volume is not detected at all.

hptiop(4) had operated normally on FreeBSD 7.2-RELEASE.

If you have invalid mount options, reboot, and first try the following from
the loader prompt:

     set vfs.root.mountfrom.options=rw

and then remove invalid mount options from /etc/fstab.

>How-To-Repeat:
Try to boot FreeBSD 8.1-PRERELEASE with RAID volume under HighPoint RocketRAID 3xxx/4xxx.
>Fix:
I do not understand the cause though I am debugging.

During boot FreeBSD 7.2-RELEASE, xpt_scan_lun() (in src/sys/cam/cam_xpt.c) seems to be called immediately after hptiop(4) is detected. 
However, during boot FreeBSD 8.1-PRERELEASE, scsi_scan_lun() (in src/sys/cam/scsi/scsi_xpt.c) seems never to be called after hptiop(4) is detected.
Probing RAID volumes seems not to start at all.

I hope this problem solves by the time FreeBSD 8.1 is released.
