How to monitor raid hardware on Linux server

Hi, I am using CentOS 5.11 on IBM x3200 M3 machine.
There are 4 SAS drive (RAID5).
I succesfully installed OS, anyway I would to be able to monitor single hard disk status.
Controller is:

IBM ServeRAID M1015 SAS/SATA Controller

I tried with SAS2IRCU utility, but it seems not working fine.

# ./sas2ircu LIST

Thank you

Not familiar with Centos, But usually the first inkling of RAID issues is an amber led on one of the hard drives, or worse red.
This will be an interesting post to follow, as I have considered putting up an Ubuntu or Suse server here, and that would also be my question.

Most modern servers have a module installed that allows you to connect to it's hardware and RAID controller remotely via an IP address and a web-browser. On Dell it is the "iDRAC", and on HP "ILO". As far as I know IBM's X servers have something similar. It just needs to be configured. Once that is done you should see the exact state of the hardware by logging in to that module.

Hi, I would like to use something that is capable of sending email in case of disk failure (as in software raid with mdadm for example)
