RAID Physical Device Access - Where to begin?


I need to access each drive of a RAID array in order to update the firmware - I am completely new to linux.

I think there are probably some potential challanges along the way to get this "working"

For example, it seems to me that the array may present itself to application code as a single device. I need to drill down into the RAID and talk to each physical device in turn via some sort of pass-through mechanism.

I'm currently pretty lost - can anyone point me in the "right" direction

thanks,
pj

First the question: what type of RAID do you have?

- external true hardware RAID with a single connector to the machine?
- internal true hardware RAID?
- internal fake RAID?
- software RAID?

Reuti,

Thank you for taking the time to consider my problem.

As I understand the situation - as yet I haven't actually seen the particular installation(s) - there is a hardware RAID controller running under some flavor of linux; it is a SAS RAID interface talking to SATA drives.

I will get more information in the next few days I suspect. I'll post that as soon as I get it.

regards,
pj
