Issue/Introduction

One LPAR showing up as inactive in CPF status. This was after getting a message this morning on the HUB LPAR: N 0020000 SDV21 19044 09:45:54.49 S0661452 00000010 TSS9807I COMMUNICATIONS FAILURE (0611), COMMAND NOT SENT TO DESTINATION S ENFSA21 N 0000000 SDV21 19044 09:45:54.49 S0661452 00000210 IEF196I TSS9807I COMMUNICATIONS FAILURE (0611), COMMAND NOT SENT TO N 0000000 SDV21 19044 09:45:54.49 S0661452 00000210 IEF196I DESTINATION ENFSA21 N 0020000 SDV21 19044 09:45:54.49 S0661452 00000010 TSS9815I CAICCI REASON TEXT: RECEIVER NOT FOUND N 0000000 SDV21 19044 09:45:54.49 S0661452 00000210 IEF196I TSS9815I CAICCI REASON TEXT: RECEIVER NOT FOUND

Cause

The problem was reproduced in-house.  A routine that cleans up CCI resources left around by address spaces that have ended mishandled the second start of TSS. This occurred because it did not properly check the ASID of the terminating task against the owning ASID of the resources. The error is specific to tasks that run as SUB=MSTR. 

Environment

z/OS

Resolution

Fix ST07366 has been written to solve the problem.
To implement: Deploy updated CAW0LOAD, refresh LLA if necessary and restart the ENF address space.
