Question List RAID devices?

With bioctl, I can get info on a particular RAID device. For example:

Code:
# bioctl softraid0
Volume      Status               Size Device  
softraid0 0 Online       938117554176 sd2     RAID1 
          0 Online       938117554176 0:0.0   noencl <sd0m>
          1 Online       938117554176 0:1.0   noencl <sd1m>
But how can I get a list of RAID devices? i.e., if there were multiple RAID devices, what could I execute to list them (softraid0, softraid1, etc.)

bioctl without args gives usage, and I couldn't find anything on the bioctl or softraid man pages that suggested an appropriate incantation.

You can try one of these commands :
$ sysctl -a|grep softraid
$ dmesg|grep softraid

Thanks - hadn't thought of sysctl.

I don't think I want to rely on dmesg because that eventually wraps, no? I think the softraid device list would only show up there when first discovered, so after some period of time it might scroll off.

/var/run/dmesg.boot will keep an "unwrapped" dmesg -- but it will not survive a drop to single user mode and subsequent return to multiuser.

It also won't show any RAID devices added after boot.

Seems odd that there's no straightforward command to list RAID devices. Seems like bioctl should do it somehow.

Oh well...sysctl it is.
