RAID 1 - How to monitor it?

[nydiow]

Hello guys, its me again!

We need to monitor with pandora one server with 2 disks in RAID 1 (http://en.wikipedia.org/wiki/Standard_RAID_levels).

The idea is to know with the both disks are running ok or not (one ok, other fail and vice-versa)

Is that possibile with Pandora? we'll use some Linux OS

Thanks!

Best regards!

Which model are the servers? DELL, HP, Fujistu Siemens?

You can do it using SNMP OIDs.

HP                                1.3.6.1.4.1.232.3.1.3.0   (this return a number: 2=ok, 3=degradate, 4=failure)

DELL                              1.3.6.1.4.1.674.10893.1.20.130.4.1.4.1 (3=ok, if is diferent, something is wrong)

Fujitsu Siemens                1.3.6.1.4.1.231.2.10.2.11.2.1.0 (This OID indicates the Global state, not only RAID disk failure. 1=OK, 2=Degradate,3=Error, 4= Failure)

You have to install provideer administrative tools (DELL Open Manager, HP insight Manager ...) Look for them in the official web page.

Good luck

I doing by SW Raid1 on Debian 6.0

My solution!

# Module for RAID1
module_begin
module_name hds_raid1
module_type generic_data
module_exec mdadm --detail /dev/md0 | grep "Active Devices" | cut -d: -f2 | sed 's/ //'
module_description Numero de dispositivos em Raid1
module_end

I have 2 disks in Raid1, if the value is different of 2 = PROBLEM!
