Raddr raddr is not a valid real subchannel address.

Explanation

When using the CHANNEL or MMC protocol, the radder operand on the EWXCONN LINK command was incorrectly specified. (It must be a three- or four-character hexadecimal number specifying the even subchannel address of a read/write address pair.)

System action

Command processing ends. The system status remains the same.

System programmer response

None.

User response

Reenter the EWXCONN LINK command with the correct subchannel address.
