This operation reports the storage control sessions that exist for a storage control. You can perform this operation regardless of whether XRC or concurrent copy is active on the system. You can only issue the MODIFY command with the LISTSESS operation from a system which has the ANTAS000 address space active.
Specify a device address for a device that is attached to the storage control for which you want session information. You can also specify the word ALL to obtain information about all the sessions in the system. The storage control LIC must at least support concurrent copy.
LISTSESS, LSTDVCS, DVCDATA, and SCDATA may now all display 'E' for the storage control session type, representing an XRC enhanced (multiple reader) session.
When using LISTSESS with a device address, you may also include the E parameter, to obtain a display of the XRC enhanced (multiple reader) session structure.
