Hello all,
I have just recently setup a RAID 1 system running FreeBSD 6.0-RELEASE
on an Adpatec 1200A card. Getting the system installed and working seems
to have been the easy part. What I am trying to do now is find a simple
and reliable way to monitor the array. So far I have tried to get
raidutil. acccli, and hptraidconf (Highpoint software) working. The only
thing that works is atacontrol. Here is what I have come to discover
(please tell me if I'm wrong) ..
raidutil is for asr systems (I'm have ar0)
acccli is for aac systems (again, ar0)
hptraidconf requires the highpoint driver which I don't seem to need in
6.0. However, the software does work with some minor tweaking of
symlinks in /usr/lib.
So, here's my question. It is reasonable to setup a cron job to monitor
the output of atacontrol status ar0 and if I see anything other than
READY, send an alert? I would then use the cards bios to handle the
rebuild of the array with the new drive.
The other option that I can think of is to load the Highpoint Rocketraid
driver but I don't know if that's a good idea or not. I'm assuming the
hptraidconf software will detach the controllers if I'm using their
driver. However, all I did to get the system installed as to create the
array using the cards bios and put the 6.0 disc in. The installer found
ar0 and I installed to it.
Any help would be greatly appreciated. I've looked and looked all over
google and the this mailing list but most posts are about different
cards using asr.
Thanks much,
Demian
