I'm using SNMP (polling not traps) to monitor a Snap Server with MIB-II (RFC 1213). Since there is no specialized MIB for this device I am stuck via standard MIB-II. My main goal is to poll the disks and make sure they are not disconnected and mounted. I'm really just looking for best practice here since I'm not much of a Linux admin.
The snap server has a RAID 1.
My plan is to monitor /dev/sda, /dev/sdb, /dev/sdc ect. Starting at OID: .22.214.171.124.126.96.36.199.188.8.131.522 and up. Right now the string just returns /dev/sda/ which I told my software is the proper string to return. If disk 0 goes down I assume it will no longer return /dev/sda for .184.108.40.206.220.127.116.11.18.104.22.1682 at least this is what I'm hoping.
Can anyone confirm my suspicion on this one? I don't really have an easy way of testing this one without physically building a PC and unplugging a drive as the linux boxes I have access to are in production.
