Vantage task is receiving the error "VAN0850E TCP/IP Request: BIND failed, ERRNO= 13" during startup

Products

• Vantage Storage Resource Manager

Issue/Introduction

During Vantage task startup, the following messages are received almost immediately: 

VAN0850E TCP/IP Request: BIND          failed, ERRNO=    13
GENTCPSV FAILED DURING INITIALIZATION  

The Vantage task fails to startup, and shuts down almost immediately.

 

Environment

Release : 14.1

Component : Vantage Storage Resource Manager

Cause

The port number being used by the Vantage task has not been properly assigned in the TCP/IP task. 

Resolution

The TCP/IP task needs to have the Vantage port defined to it and allocated for Vantage.  Once this is done, the Vantage task is able to initialize successfully (without TCP/IP errors). 

Note that in the customer's case the following items were NOT a factor in this problem: 

1) The same Port number was being used (successfully) by multiple Vantage tasks, including the failing Vantage task, but each Vantage task was running in a separate LPAR within the Sysplex.

2) The Vantage VKGPARMS parameters TCPPARMD  and TCPPARMM were not defined for any of the Vantage tasks (and these parameters do not have any default value assigned if they are not specified).  Interestingly, the TCP/IP tasks did not have a SYSTCPD DD statement defined, but info from this DD is needed to define the values for the TCPPARMD and TCPPARMM Vantage parameters.
