Hi,

I have not noticed this before, but my system rebooted this morning and
in the following security report I found a lot of messgaes in the
dmesg-part like:

+(probe0:arcmsr0:0:16:1): INQUIRY. CDB: 12 20 0 0 24 0
+(probe0:arcmsr0:0:16:1): CAM status: Command timeout
+(probe0:arcmsr0:0:16:1): Retrying command
+(probe0:arcmsr0:0:16:1): INQUIRY. CDB: 12 20 0 0 24 0
+(probe0:arcmsr0:0:16:1): CAM status: Command timeout
+(probe0:arcmsr0:0:16:1): Retrying command

And it seems that bus 16 is:
+pass6 at arcmsr0 bus 0 scbus0 target 16 lun 0
+pass6: <Areca RAID controller R001> Fixed Processor SCSI-0 device

The system has been running
FreeBSD zfs.digiware.nl 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #3: Wed
Nov 14 13:25:55 CET 2012
root@zfs.digiware.nl:/usr/obj/usr/srcs/src9/src/sys/ZFS  amd64
for already a while.

Anybody suggestions as to why I have these messages?

They are during the boot sequence, so no smartd talking to the disks at
that moment.
