2. Configure the MCS devices to send their SNMP traps to the management server IP alias; use the IP
alias obtained in the previous step:
# mcs_webtool -H MCS_IP_address -p MCS_Admin_password \
-i -a IP_address -e IP_address
Adding trap receiver 1: IP_address
Enabling trap receiver 1: IP_address
Trap Receiver Status for MCS at MCS_IP_address:
Authentication Traps: Disable
Trap Receiver 1: IP_address Enable
Trap Receiver 2: 0.0.0.0 Disable
Trap Receiver 3: 0.0.0.0 Disable
Trap Receiver 4: 0.0.0.0 Disable
3. Verify that the SNMP trap destination has been set properly on the MCS devices:
# mcs_webtool -H MCS_IP_address -p compaq -i
Trap Receiver Status for MCS at MCS_IP_address:
Authentication Traps: Disable
Trap Receiver 1: IP_address Enable
Trap Receiver 2: 0.0.0.0 Disable
Trap Receiver 3: 0.0.0.0 Disable
Trap Receiver 4: 0.0.0.0 Disable
Proceed to “Task 17: Finalize the Configuration of Compute Resources”.
3.18 Task 17: Finalize the Configuration of Compute Resources
Perform the following tasks only if you configured SLURM or LSF or both; bypass this task if neither
SLURM nor LSF are configured.
• “Perform SLURM Postconfiguration Tasks” (page 86)
• “Perform LSF Postconfiguration Tasks” (page 87)
3.18.1 Perform SLURM Postconfiguration Tasks
If SLURM was configured, follow this procedure to finish configuring SLURM:
1. Begin this procedure as the root user on the head node.
2. Use the SLURM postconfiguration utility to update the slurm.conf file with the correct processor
count and memory size. If a QsNet
II
interconnect switch is present, an elanhosts file is created with
an entry for each compute node. The elanhosts file is part of the QsNet
II
switch support that is
provided by SLURM.
# spconfig
Detected the Quadrics Elan interconnect; configuring SLURM support...
The new 'elanhosts' file contains entries for 16 nodes...
Configured nodes n[1-15] with 2 CPUs and 8108 MB of total memory...
Configured node n16 with 4 CPUs and 9549 MB of total memory...
Restarting SLURM...
SLURM Post-Configuration Done.
In this example, the spconfig utility was run on a system with a QsNet
II
interconnect. For all other
interconnect types, the first two lines of the command output are not displayed.
NOTE: If a compute node did not boot up, the spconfig utility configures the node as follows:
