I'm running 6.2-RELEASE on an ASUS A7N8X-E Deluxe motherboard. It has the
Silicon Image sil3112 RAID chip on it driving two SATA drives. After much
searching, it seems that it's fake RAID is not supported. No problem,
but dmesg sees it and it's status:

ad4: 305245MB <Seagate ST3320620AS 3.AAC> at ata2-master SATA150
ad6: 305245MB <Seagate ST3320620AS 3.AAC> at ata3-master SATA150
ar0: WARNING - mirror protection lost. RAID1 array in DEGRADED mode
ar0: 305244MB <Silicon Image Medley RAID1> status: DEGRADED
ar0: disk0 DOWN no device found for this subdisk
ar0: disk1 READY (mirror) using ad6 at ata3-master


So,

- Is this warning just a part of a not-completely supported chip? (ie
only the status of ar0 can be determined?) 

- If yes, then the warning/status msgs should be ignored until a real
mirroring solution is put in place?

- Is there any problem with the basic SATA functionality of the chip? It's
listed as supported in the ata manpage, but Soren Schmidt seems to
dislike it quite a bit.

- And to mirror the two drives then, should I be looking at Gmirror?
Something else?


TIA for all help.


-Jason
