Working with channel paths

Channel paths can be dedicated, reconfigurable, shared, or spanned. The following list explains when to use which channel path operation mode.

DED

Dedicated; if you want only one logical partition to access a channel path, specify that channel path as dedicated. You cannot reconfigure a dedicated channel path. This is the default mode.

REC

Reconfigurable; if you want only one logical partition at a time to access a channel path and you want to be able to reconfigure the channel path from one partition to another, specify that channel path as reconfigurable.

SHR

Shared; if you want more than one logical partition to access a channel path simultaneously, specify that channel path as shared.

SPAN

Spanned; if in XMP processors for certain channel types, you want to have a shared channel accessed by partitions from multiple logical channel subsystems, specify that channel path as spanned.

On the Add Channel Path panel, enter a channel path type and use F4=Prompt for the operation mode to find out the allowed operation modes for the specified type.

Channel paths can also be categorized as static or managed. For more information, see Defining managed channel paths.
