Thanks for the reply.

I looked through the driver code and wrote an "ipsstat" utility that 
uses the user command ioctl to query what is going on.  The output isn't 
pretty; my main purpose is to have someone be notified if a logical 
drive goes into degraded mode.

Example output below.  The implementation is pretty straightforward; 
I'm happy to hand out the source.

Regards,

Jan.
