I have a number of servers with almost identical hardware (Supermicro MB, Areca 1210 or 1220 RAID card).
These span from OpenBSD 4.5 to 5.0. In anything before 5.0, I am able to monitor the RAID status via snmp at OPENBSD-SENSORS-MIB::sensorStatus. The 5.0 boxes are returning unknown status (and the device IOD has changed from 3 to 46). sysctl reports differently in 5.0: 4.9 box (this is same in 4.8): hw.sensors.arc0.drive0=online (sd0), OK 5.0 box: hw.sensors.arc0.drive0=unknown (sd0), UNKNOWN I can't seem to find any mention that I should be doing something different as of 5.0. Has something broken? Do I need to do something different? Thanks for any help. dmesg from 4.9 box: OpenBSD 4.9 (GENERIC.MP) #819: Wed Mar 2 06:57:49 MST 2011 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 3486973952 (3325MB)
