SCDATA operation (XRC, CC)

This operation reports the status of a session on a primary storage control. You may perform this operation regardless of whether XRC or concurrent copy is active on the system. You can only issue the MODIFY SCDATA command from a system which has the ANTAS000 address space active.

The following example is the command syntax:

F ANTAS002,SCDATA ddd ss X

The following definitions apply to the syntax above:

ddd: Specifies the address of a device that is attached to the primary storage control you want to display. The storage control must have XRC-capable Licensed Internal Code (LIC) that supports this function.
ss: Specifies the storage control session number (which you can obtain by issuing a F ANTAS000,LISTSESS xxxx command, see LISTSESS Operation for more information).
X: Specifies that the channel extender status for a device be provided by way of the ANTX8970I message.

Result: If you specify the X parameter, the following example message displays the channel extender status for the device:

ANTX8970I F40 CHANNEL EXTENDER TYPE=CNT LEVEL=01 ALLOC=4000  
    BUFFER=000B0000

Result: If there is no channel extender, the following message appears:

ANTX8970I 0F40 NO CHANNEL EXTENDER

Without the X parameter, the command returns a system data mover message of number ANTX8936I.

Example: If you issue the following command to list the current status of session 01 on the primary storage control that is associated with device F40:

F ANTAS002,SCDATA 0F40 01

Result: An example of the output is:

ANTX8936I 0F40 - SESSION=XA01 RESIDUAL=0005 NEXTDEV=0F40 MAXSIZE=2048
                 TIME(1997.234 12:24:32.273568) TIMEOUT(00.05.00)

The following is a sample message produced by the SCDATA command:

ANTX8936I 0F60 - SESSION=XA09 RESIDUAL=0000 NEXT DEV=0F60* MAXSIZE=E000 
TIME(************************) TIMEOUT(00.05.00)

Note: For a description of the ANTX8936I message, refer to z/OS MVS System Messages, Vol 1 (ABA-AOM).
