Configuring the Controller
Note: If the other controller was unplugged then plugged
back in or replaced by a different controller, the surviving
controller will automatically unkill the other controller.
To unkill the other controller:
1 From the System Menu, select Other Controller Menu and
press Enter.
The Other Controller menu is only available if the system is
configured to run in active-active mode.
The Other Controller menu appears.
2 Select Unkill Other and press Enter.
The system confirms that you want to make the change.
3 Select Yes and press Enter to make the change.
The other controller boots.
4 Press Esc to return to the Other Controller menu.
Disabling SCSI Channel 3
You can disable SCSI channel 3 from the Flash Utility.
Note: Because disabling SCSI channel 3 may affect the
configuration of nonvolatile memory, SCSI channel 3
cannot be disabled if host data is present. Shut down the
controller gracefully to flush out host data (see Rebooting
the Controller on page 5-2), or select Clear Battery Back Up
from the Flash Utility menu, which will clear the host data.
Disabling SCSI channel 3 results in only one available host channel,
meaning that the controller can only be run in stand-alone single-
port mode.
