CAUTION: Wait for FRUTIL to quiesce the device ports—indicated by an “All device
ports quiesced” message. Failure to allow the ports to quiesce might result in data
loss. Quiescing might take several minutes.
7. Replace the failed I/O modules:
a.
Disconnect the SCSI bus cable from each failed I/O module (see
Figure 4–11).
b.
Remove all failed I/O modules.
c.
Install all replacement I/O modules.
d. Reconnect the appropriate SCSI bus cable to each replacement I/O module.
8. Press Enter/Return to resume device port activity and restart the “other
controller.”
NOTE: A controller restart can take as long as 60 seconds, indicated by the temporary
cycling of the port LEDs and a F
LASHING
reset button.
IMPORTANT: If the “other controller” did not restart, press the controller reset button.
9. Enable failover and re-establish the dual-redundant configuration with one of the
following commands:
SET FAILOVER COPY=THIS_CONTROLLER
or
SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER
This command copies the subsystem configuration from “this controller” to the
“other controller.”
10. If desired, verify the failover configuration with the following command:
SHOW THIS_CONTROLLER FULL
11. Disconnect the PC or terminal from the controller maintenance port.
