This error occurs when an instance has a VCMP socket error, The “sybase” user must own the VCMP socket (/tmp/vcmp_socket) before it can read and write to the socket and communicate with VxFEN.
Use the ls -l UNIX command to validate that the “sybase” user owns /tmp/vcmp_socket:
ls -l /tmp/vcmp_socket
If the “sybase” user does not own /tmp/vcmp_socket, change the ownership using the UNIX chown command:
chown sybase /tmp/vcmp_socket
