Working with Virtual Channel-to-Channel Adapters

A virtual channel-to-channel adapter (CTCA) provides a communications link between two virtual machines, regardless of whether your installation has defined a real channel-to-channel adapter. To check the status of any virtual channel-to-channel adapters in your virtual machine configuration, enter:

query virtual ctca

Note: z/VM® supports CTCAs designed after 1981. For more information on what commands are supported by the z/VM VCTCA, see the IBM® Channel-to-Channel Adapter Manual.
