Moving Unshared Channel Paths
You can move reconfigurable channel paths owned by one LP to another LP.
Moving Unshared Channel Paths from a z/OS System
1. Select the LP that owns the channel path to display channel path information for
the LP.
2. Move the channel path from the z/OS console.
a. Enter CF CHP( nn ),OFFLINE , where nn is the number of the desired channel
path, from the z/OS operator console that has the reconfigurable channel
path online.
b. Enter CF CHP( nn ),ONLINE , where nn is the number of the desired channel
path, from the z/OS operator console that is the target LP.
Notes:
1) If a channel path is configured offline while the LP is isolated and
remains offline when you change the LP’s isolation status from enabled
to disabled, the channel path must be configured offline again. See
“Releasing Reconfigurable Channel Paths.”
2) If the channel path you want to move is currently assigned to a
deactivated LP, you must configure it offline from the hardware console.
3) If the LP is not running a system control program that supports channel
path configuration commands, you can move the channel path from the
hardware console.
Moving a Channel Path from the Hardware Console
1. Select the LP that owns the channel path to display channel path information for
the LP.
2. Select a reconfigurable channel path from the CHPIDs work area. Drag and
drop the CHPID on the Reassign Channel Path task available from the CHPID
Operations task list.
3. The Reassign a Channel Path panel displays the targeted channel path, the
current owning LP, and a list of target LPs to which you can reassign the
channel path. Select the LP to which you want to reassign the channel path.
4. Click on the Reassign push button and confirm the action to release the channel
path.
5. When the “Requested operation is complete” message appears, click on the OK
push button.
Releasing Reconfigurable Channel Paths
Use this procedure when the owning LP has LP isolation enabled.
1. Select the LP that owns the channel path to display channel path information for
the LP.
2. Select a reconfigurable channel path from the CHPIDs work area. Drag and
drop the CHPID on the Release task available from the CHPID Operations task
list.
A Confirm the Action panel will display warning you that the channel paths will
be released and made available for reassignment to other LPs. Confirming the
action will release the channel path and a “Requested operation is complete”
message will display. Click on the OK push button to complete the task.
