5.1.3 Channel path spanning

With the implementation of multiple LCSSs, a channel path can be available to LPARs as
dedicated, shared, and spanned.
Although a shared channel path can be shared by LPARs within a same LCSS, a spanned
channel path can be shared by LPARs within and across LCSSs.
By assigning the same CHPID from different LCSSs to the same channel path, a PCHID for
example, the channel path can be accessed by any LPAR from these LCSSs at the same
time. That CHPID is then spanned across those LCSSs. Using spanned channels paths
decreases the number of channels needed in an installation of z Systems servers.
