DFS2062I MODENAME UNKNOWN TO VTAM NODE x (USER y).
Explanation
An unknown mode name condition was returned on a VTAM® SIMLOGON issued due to an IMS /OPNDST command for NODE x or USER y. Either an incorrect mode name was specified on the IMS /OPNDST command or a mode table entry was not defined to VTAM with the specified name.
System action
The attempt to establish a session with NODE x or USER y has been terminated. (1) An IMS trace log record (X'67') containing pertinent information was produced with an ID of CVCT. (2) An IDC0 trace table entry is created if the IDC0 trace is active (for nonexisting dynamic terminals).
Programmer response
When the problem is corrected, session initiation can be attempted again using an IMS /OPNDST command. The session can also be requested or initiated by NODE x or USER y.
