Yes, that's the first thing to check. I could not quite figure out
from the OP whether
the NCR card was removed and the Qlogic KZPBA-CX replaced it or that
the Qlogic
was added to the system.
In the latter case disks connect to the Qlogic card will have another
controller letter
(DKDn00 or something). Even if the Qlogic replaced the NCR card but
was placed in another
slot then the controller id might change.
The real problem may be in the personality module though. The
dipswitch settings must be
set exactly right otherwise weird things happen.
With the Qlogic KZPBA-CX in place, what is the output of >>> SHOW
DEVICES
