Sense code 0857

SSCP-LU Session Not Active: The SSCP-LU session, required for the processing of a request, is not active; for example, in processing REQECHO, the SSCP did not have an active session with the target LU named in the REQECHO RU.

Bytes 2 and 3 following the sense code contain sense-code-specific information.
0000
No specific code applies.

VTAM® hint: The primary logical unit (PLU) or secondary logical unit (SLU) is not available.

0001
The SSCP-SLU session is in the process of being reactivated.
0002
The SSCP-PLU session is inactive.

VTAM hint: For a USERVAR, an APPL or CDRSC definition with the same name as the USERVAR was found and was not active.

0003
The SSCP-SLU session is inactive.

VTAM hint: For independent logical units, the independent logical unit is inactive.

0004
The SSCP-PLU session is in the process of being reactivated.
0005
The SSCP lost connectivity with the PLU after the LU-LU session was started, and has no other way to learn that the session has ended; the SSCP either never had a session to a gateway node in the LU-LU session path, or had previously lost connectivity to it.
0006
The SSCP lost connectivity with the SLU after the LU-LU session was started, and has no other way to learn that the session has ended; the SSCP either never had a session to a gateway node in the LU-LU session path, or had previously lost connectivity to it.
0007
The selected ALS for the OLU is not in a state permitting LU-LU sessions to be established using it. The condition is detected when the session request (BFINIT) was received, but, when the request was processed, the ALS was no longer in an active state. The session request is rejected.
0008
The selected ALS for the DLU is not in a state permitting LU-LU sessions to be established using it. The condition is detected when the session request was being processed in the DLU domain and the ALS selected for the DLU is no longer in an active state. The session request is rejected.
