by placing the resource_management role on two or more nodes. These nodes are not members
of any availability set, and the SLURM and LSF-HPC with SLURM software is not managed by
any availability tool.
When you assign two or more nodes with the resource_management role, SLURM availability
is automatically enabled. If you assign the resource_management to two or more nodes, you
must manually enable availability for LSF-HPC with SLURM; see “Perform LSF Postconfiguration
Tasks” (page 108) for instructions.
Standard LSF also contains it's own automatic failover mechanisms. See the Platform LSF
documentation for more information on node failure scenarios with standard LSF.
1.9.7 Using the Improved Availability Planning Worksheet
After you have completed the advance planning of your service availability strategy, use the
worksheet in Table 1-3 to record the following information:
• The node names to associate into availability sets.
• The availability tool that will manage the services in each availability set (if you installed
and configured more than one availability tool).
• The roles (and thus, the services) to assign to both nodes in each availability set
The cluster_config utility prompts you for this information, so have the worksheet handy.
