I recently worked on a project that requires scheduled status monitoring of a RAID1 (mirrored) volume facilitated via the inexpensive JMicron JMB36x chipset.
To my disbelief, JMicron's xRaidSetup (the facility to create RAID volumes) does not have the ability to report RAID status via email notification which other brands such as Marvell do (I believe Silicon Image as well). So, I had to do it the hard way - reverse engineer xRaidSetup.exe and painstakingly via dis-assembly figure out what it does to get a RAID volume's status (all I wanted to know was if it's running normally!).
I've created xRaidChecker (download) for those who needed the same feature. It's a console application that returns a number indicating the RAID status of the first RAID volume (currently only supports one volume).
Return value of 1 indicates volume is running normally. Any other values indicate an 'Abnormal' status according to xRaidSetup.exe. I'm convinced, however, that there must be specific values that indicate statuses such as 'Rebuild Required' and 'Rebuilding'. If you encounter a return value other than 1, do find out what it means and let me know.
p.s. xRaidChecker needs to be run in elevated command prompt (run as Administrator), or, as I've got it set up, via Task Scheduler running with System privileges and sending out email notifications via a batch file.
p.p.s. JMicron's xRaidSetup must already be installed and your RAID volume set up before you run xRaidChecker (it uses xRaidAPI.dll).
