These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD
using either SAS or SATA II drives.
arcmsr
supports management and monitoring of the controller through the
bioctl(8)
and
envstat(8)
commands.
Please note, however, that to use some features that require special
privileges, such as creating/removing hot-spares, pass-through disks
or RAID volumes will require to have the
password
disabled in the firmware; otherwise a
Permission denied
error will be reported by
bioctl(8).
When a RAID 1 or 1+0 volume is created, either through the
bioctl(8)
command or controller's firmware, the volume won't be accessible until
the initialization is done. A way to get access to the
sd(4)
device that corresponds to that volume without rebooting, is to issue
the following command (once the initialization is finished):
$ scsictl scsibus0 scan any any
The
arcmsr
driver will also report to the kernel log buffer any error that might
appear when handling firmware commands, such as used by the
bioctl(8)
command.
EVENTS
The
arcmsr
driver is able to send events to
powerd(8)
if a volume or any drive connected to the volume is not online.
The
state-changed
event will be sent to the
/etc/powerd/scripts/sensor_drive
script when such condition happens.
