OTOH any important status change in the RAID set is reported by the ciss(4) driver. Monitoring /var/log/messages might to the job. I posted this some weeks ago to the list [2], so you can get some impression if this is good enough for your requirements. > environmental monitoring: > > It seems that the mbmon port does not work with the DL385 hardware.

It would be very nice to have hardware monitoring via iLO. This can be achieved under so called supported platforms, aka Linux or Windows, where you have to run HP agent software which does hardware monitoring of the underlying hardware. IMHO a rather weired approach, seems like HP has solved the chicken-and-egg problem ;) IIRC the results of the agents are being written in some kind of message buffer which can be polled by the iLO. Unfortunatelly the iLO doesn't have any OS independent logic to do all the stuff on its own. I address this as feature request several times at HP but it seems that one single customer is not important enough. > "raid5-angst" - opinions: I guess this depends on your application. For database applications RAID5 might result in poor write performance. In such scenaries I prefer 3 RAID1 sets where I'm distributing my table spaces. If you need just max file capacity with redunandy there are not many alternatives to a RAID5 set. Speaking for HP's SCSI drives I've never seen two disks failing at the very same time in the past 5 years. After all they are quite reliable. Nevertheless, this is no guarantee. But keep in mind, of both sub-mirrors of a RAID 1/0+1 fail a the same time, the result is the same.
