[rhn-users] Hardware RAID health monitor

[Jeremy Eder]

If your hardware is dell, they have mibs for net-snmp for array status (among a billion other things...).
 
Basically, it will show the array status as an integer; you can then configure your snmp monitoring application to snmpwalk the box periodically, and alert you as to array status.  For example, if array status snmpmib !=0 then email me.
 
Most monitoring apps should be able to do this for you.
 
If it's not a dell, perhaps the manufacturer has similar mibs for you to load into net-snmp ?

Thank you.  Yes, I tried to ask them first.  Here is what I asked their tech support guy:

Ok, this sounds a bit stupid, but is there a website / documentation that explains the benefits of using a driver like this?

Ultimately I'm looking to get emails when the hardware detects a drive is down or not doing well.  Beyond that I care about performance, and possibly the ability of the file system to automatically grow should I throw in more hard drives.

But I'm unsure if I get all this by installing a driver.  Do I?

--- and here is their answer:


Bernt, 
 
Not really...  I'm pretty sure there will be a driver in the OS already.  If there is then I would just use that.  We do not have a utility that sends emails or pages when a drive is failing.   
 
Thank you,

So I'm guessing that I'm out of luck.  What hardware RAID card should I have gotten?
