Displaying the control device state

The control device is in either a neutral or a switched state. When it is neutral, the control device
accepts commands from any channel that has established a logic path with it and accepts
commands from alternate managers. When the control device is switched, it establishes a logical
path and accepts commands only from that logical path ("device allegiance"). Commands from
other paths cause a FICON CUP Busy Error. Most "write" operations from alternate managers are
also rejected.
Device allegiance usually lasts for a very short time. However, under abnormal conditions, device
allegiance can get "stuck" and fail to terminate. It might cause the switch to be unmanageable with
CUP, and you will continue to receive the FICON CUP Busy Error. In this case, you should check the
control device state and the last update time to identify if the device allegiance is stuck. The Web
Tools Switch Admin displays the control device state and last update time (see
page 220). You can click Refresh to get most recent update.
