IBM Spectrum LSF Suite 10.2.0.14 Fix 601719 Readme File

Abstract 

This contains bug fixes for IBM Spectrum LSF  V10.1 Fix 601649

 

Description

Readme documentation for IBM Spectrum LSF Suite V10.2.0.14 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issues:

This fix adds a new parameter LSB_RC_EXTERNAL_HOST_ABNORMAL_TIME to lsf.conf that controls the number of minutes that LSF waits before timing out LSF resource connector hosts that are in an abnormal status (that is, closed_LIM, unavail, or unreach status).

 

Syntax
LSB_RC_EXTERNAL_HOST_ABNORMAL_TIME=soft_timeout_integer:hard_timeout_integer

Description
The timeout values (in minutes) and LSF behavior when a LSF resource connector host reaches its soft and hard timeout limits. Specify integers for the values and separate the values with a colon (:).

The value before the colon means a soft timeout. When a host reaches its soft timeout, and there are still jobs on it, the mbatchd daemon will log a warning message. Cluster administrators can monitor this log message, and take immediate action, such as check and restart the LSF daemons on the host. If there are no jobs on the host when the host reaches the timeout, the host will be relinquished. The default soft timeout is 10 minutes.

The value after the colon means a hard timeout. When a host reaches its hard timeout, LSF will relinquish the host, and jobs on the host will be re-queued or exited. The default hard timeout is 60 minutes.

Default:
10:60
