Editing RAID Cards (section)

== CLI notes ==
On all of our 2450 servers and a handful of old FreeBSD boxes, we are running on adaptec RAID cards. 

The CLI program is <tt>aaccli</tt> on FreeBSD and <tt>afacli</tt> on linux

Once you're in the CLI, open the container - either `open aac0` on fbsd or `open afa0` on linux - everything else is the same regardless of the OS.

Here are the most common things we ever do:

type exit to leave it.

All the mirrors you are getting are healthy - so even if a drive fails you should be ok.  If an unexplained system crash occurs, after restarting all the systems you should check the mirrors with `container list /f` to see if one has degraded (one disk has died).

Once in a while a mirror degrading will cause the system to crash - but not usually - usually it is just silent.
