I am interested in determining the status of a RAID array on my system (using Debian, and Intel ICH10R sata RAID controller = fakeRAID). What I have learned so far is that:
- I can use CSMI I/O control codes in order to get the status (and a bunch of other info) about the RAID.
- I need to open a device node for the host bus adapter in order to get a file descriptor so that I can use ioctl() and send the CSMI control codes.
The constraint for my problem is that the solution must be done using C or C++, and not through a shell script. I have managed to solve this in Windows, so I know that at least it is possible.
Right now, I'm stuck because I am not sure of the name of the device node for the hba, and I'm uncertain as to how I can find out. Also, I'm wondering if there's a better way... I have thought about libdevmapper, but I'm still unsure how I could use it.
Does anyone know what concepts I still need to look into, and the direction that I need to look?
Thanks for your help!
