Considerations

When deleting signaling paths, consider the following:

The operator cannot stop the last active signaling path to or from another system in the sysplex. MVS™ requires full connectivity (at least one outbound and one inbound signaling path) between each of pair of systems in a sysplex.
When an MVS system in the sysplex is running as a guest under VM, exercise care when changing paths. If a device is detached and linked via CP commands while it is online to MVS, MVS boxes the device, which makes it unusable until the guest MVS system is re-IPLed.
