LSF_DATA_HOSTS

Specifies a list of hosts where the LSF data manager daemon (dmd) can run, and where clients can contact the LSF data manager that is associated with the cluster. The dmd daemon can run only on the listed hosts.

Syntax

LSF_DATA_HOSTS=host_list

Description

Note: Do not specify the LSF management host or management candidate hosts if LSF_DAEMONS_RUN_AS_ADMIN=Y is defined in the lsf.conf file.
All LSF data manager clients, including the mbatchd daemon, use this parameter to contact the dmd daemon. This parameter must be defined in every cluster that talks to the LSF data manager. Defining this parameter acts as a switch that enables the overall LSF data management features.

The order of host names in the list decides which host is the LSF data manager management host, and order of failover. All host names must be listed in the same order for all LSF data managers.

To have LIM start the LSF data manager daemon automatically, and keep monitoring it, the hosts that are listed in LSF_DATA_HOSTS must be LSF server hosts.

When the LSF data manager starts, it verifies that its current host name is on this list, and that it is an LSF server.

To change the LSF_DATA_HOSTS parameter, complete these steps:
  1. Run the bctrld stop lim command to shut down LIM on the LSF data manager candidate hosts.
  2. Run the bdata admin shutdown command to shut down the dmd daemon on the LSF data manager candidate hosts.
  3. Change the parameter.
  4. Run the bctrld start lim command to start LIM on the LSF data manager candidate hosts.
  5. Run the badmin mbdrestart command to restart all LSF management candidate hosts.
