EZY1937I

MVP system subsystem unavailable. system functions
will fail.
Explanation
 During a scan of the Subsystem Communication Vector
Table (SSCVT) control blocks, the platform code could not locate the
SSCVT associated with the indicated subsystem.

System action
 The task is terminated, and control is returned
to the system with a task completion code of 600. When the error occurs
in module MVPVXI (implying a failure during the initialization of
the Virtual Machine Communication Facility (VMCF) subsystem itself),
subsystem initialization is terminated, and control is returned to
the system with a completion code of 4000.

Operator response
 Tell the system programmer about the error.

System programmer response
 Check that the identified subsystem
is created and initialized during system initialization. See  Step 3: Configure VMCF and TNF in z/OS Communications Server: IP Configuration
Guide for more information about starting VMCF
and TNF. Check for previous operator messages that might indicate
why the particular subsystem failed to initialize. See the appropriate System
Messages book for information about possible error messages
from subsystem processing. A programming error is the most probable
cause of the problem if subsystem processing error messages occur.
If the problem cannot be remedied by modifications to subsystem definitions,
gather all available documentation, and contact the IBM® Software Support Center.
