IBM Platform LSF 9.1.1 Fix 358140 Readme File

Abstract

P101338. Fix to ensure that LSF compares both the host name and the mbatchd process ID before restarting a new mbatchd daemon process.

Description

Readme documentation for IBM Platform LSF 9.1.1 Fix 358140 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

If the master host fails and a master candidate host takes over, mbatchd might not start on the master candidate host. This issue occurs if there is some process running on the master candidate host with the same process ID as that of the mbatchd process running on the original master host.

This fix resolves the issue by comparing both the host name and the process ID of the mbatchd process (from the lsb.event.lock file in the master host) before starting a new mbatchd daemon process.
