5.10 Task 9: Image and Boot the System and Start Compute Resources
Follow this procedure to image and boot all nodes after the upgrade and start LSF:
1. Use the following startsys command on systems with fewer than 300 nodes to image and boot all
nodes. For larger hardware configurations, see the next step.
# startsys --image_and_boot
2. Use the following startsys commands on systems with more than 300 nodes. The image and boot
process for hardware configurations of this size is completed in two phases:
a. Image the nodes:
# startsys --image_only
b. Boot the nodes:
# startsys --boot_group_delay=240
NOTE: Use the --boot_group_delay=240 option only the first time nodes are booted after
being imaged; the value 240 specifies the number of seconds to wait between groups of nodes
as they are booting. For more information about this value, see startsys(8)
3. Make sure all nodes are up:
# power --status
4. If the system is configured with LSF-HPC with SLURM, run the SLURM postconfiguration utility to
update the slurm.conf file with compute node names and attributes:
# spconfig
5. Set up the LSF environment by sourcing the LSF profile file:
# . /opt/hptc/lsf/top/conf/profile.lsf
6. Determine the node on which the LSF daemons are running:
# controllsf show current
LSF is currently running on node n32, and assigned to node n32
7. Log in to the node that is running LSF if it is not running on the head node. If LSF is running on the
head node, bypass this step.
# ssh n32
8. Restart the LIM daemon:
# lsadmin limrestart
Checking configuration files ...
No errors found.
Restart LIM on <lsfhost.localdomain> ...... done
Restarting the LIM daemon is required because the licensing of LSF-HPC with SLURM occurs when
the LIM daemon is started. This means that the LIM daemon will be licensed only for processors that
are actually available at that time, which may be fewer than the total number of processors available
after all of the nodes have been imaged and are up and running.
