DISCONNECT Command
DISCONNECT Command
The DISCONNECT command logically disconnects a link on the FOX ring subnetwork
for the specified LBU object, preventing packets from traveling in the specified
direction. DISCONNECT is a sensitive command.
The DISCONNECT command syntax is
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
LBU
is a keyword specifying that an LBU name comes next on the command line.
LBU-name
is the name of the LBU ($ZZFOX.#X or $ZZFOX.#Y) associated with the
ServerNet/FX adapter that is to disconnect its left or right side from the FOX ring
subnetwork.
{ LEFT | RIGHT }
specifies the direction in which communications are to be disconnected.
Considerations
•
To better understand the effect of the DISCONNECT command, visualize a
ServerNet/FX adapter as having two sides, as shown in Figure 4-1 on page 4-18.
You must disconnect both the left and right sides of the ServerNet/FX adapter to
fully stop packets from flowing to or from the local cluster on that adapter. See
Figure 4-1 to see how the DISCONNECT command compares to the START LBU,
STOP, and ABORT commands.
•
Executing the DISCONNECT command to disconnect the left (or right) side
prevents messages from flowing in or out the left (or right) side.
•
When removing a FOX cluster from a FOX ring, disconnect the corresponding left
and right neighbors of the ServerNet/FX adapter using the DISCONNECT
command on the local cluster. Then use the ABORT command to stop the
ServerNet/FX adapter.
