Increase the timeout value for commands sent to the controller device. - controller can become slow to respond to INQUIRIES resulting in the SML off-lining the controller device. - when large RAID volumes are created along with I/O stress, the controller can be slow to respond to INQUIRIES. - set/sense config along with device resets can delay controller responses.
