ISR Statistics / fcdutil

HP Admins:

We have around 12 /dev/fcdX files. Each one I am sure belongs to each port
of the dual port FC cards that we have on this system. We are wondering what
the ISR Statistics mean when we run:

# /opt/fcms/bin/fcdutil /dev/fcd1 stat

I see a large number (to the tune of 40Million) of interrrupts and spurious
interrupts. Do these interrupts mean something? Is this something which
needs concern? Any input would be most appreciated.

Regards.
-Kennedy
