arcmsr
driver provides support for the PCI-X and PCI
Express RAID controllers from Areca Technology Corporation:
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.
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.
arcmsr
driver first appeared in
NetBSD 5.0.
arcmsr
driver was originally written for
OpenBSD by David Gwynne. It
was ported to NetBSD and extended by
Juan Romero Pardines.
