ESCON/FICON host adapter XTCC
Channel Nodes List of host channels used to establish a logical path. Each line
corresponds to one ESCON channel. The list shows the node
ID of the ESCON port in the host. The hexadecimal number
separated by a blank represents the port number of the host
channel on the ESCON Director (= link address).
The colon is followed by “chi” (= Channel Image) with a list of the
virtual channels of the host connected via this physical path.
To display formatted output of ESCON parameters, use the
“Show Node ID Details” command (see page 381).

Connecting lines to the hosts
The connecting lines from the host adapter that go over the top of the screen show the host
devices connected.
The circle at the top of the line contains the device mnemonic. If the name is underscored
and the line continuous, the connection is active; the device is reserved and a logical path
has been established.
A dashed line indicates that a path has been established but no reservation exists.
If no line is displayed, no path has been established.
