I did, and I'm not seeing anything. It does talk about this: -a alarm-function Control the RAID card's alarm functionality, if supported. alarm-function may be one of: disable Disable the alarm on the RAID controller. enable Enable the alarm on the RAID controller. get Retrieve the current alarm state (enabled or disabled). silence | quiet Silence the alarm if it is currently beeping. The alarm-function may be specified as given above, or by the first letter only (e.g. -a e). But this all seems related to turning on/off the beeper, rather than giving me some textual indication of the health of the raid system. If my server is in a colo miles away, the "alarm" buzzer is not going to be particularly useful to me. Compare this to the ami driver, which states: Logical disk status is exposed under the hw.sensors sysctl(8) and can be monitored using sensorsd(8). For example: $ sysctl hw.sensors.ami0 hw.sensors.ami0.drive0=online (sd0), OK hw.sensors.ami0.drive1=degraded (sd1), WARNING hw.sensors.ami0.drive2=failed (sd2), CRITICAL This exactly the kind of thing I am asking if arc supports, and if it doesn't (which is what I suspect), then IMHO, OpenBSD's support for Areca cards is not as awesome as its support for LSI Megaraid boards > > > > On Tue, Oct 28, 2008 at 4:24 PM, Don Jackson <[EMAIL PROTECTED]> > wrote: >> On Oct 28, 2008, at 5:46 AM, Claudio Jeker wrote: >>> >>> Have a look at the man -k RAID output. >>> >>> Especially arc(4) and ami(4) are great SATA RAID controllers on >>> OpenBSD. >> >> Does OpenBSD's arc(4) driver support any method to report RAID >> status >> and/or failures? >> >> If not, then how is an admin supposed to understand the health of arc >> supported RAID array?
