HP XC System Software Installation Guide Version 3.2.1

/hptc_cluster/adm/log/consolidated.log file and the
/hptc_cluster/adm/logs/snmptraps.log file. This enables Nagios to generate alerts for
all MCS traps posted with a priority of WARNING or greater.
1. Use one of the following methods to determine the management server IP alias:
• If Nagios is configured for improved availability, the management server IP alias is the
nagios_master_alias as defined in the /etc/hosts file:
# grep nagios_master /etc/hosts
IP_address nagios_master_alias
• Otherwise, the management server IP alias is the internal IP address of the head node:
# grep nh /etc/hosts
IP_address n16 nh hplsadm n16.localhost.localdomain
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 18: Finalize the Configuration of Compute Resources”.
3.19 Task 18: Finalize the Configuration of Compute Resources
Perform the following tasks only if you configured SLURM or LSF or both; omit this task if
neither SLURM nor LSF are configured.
• “Perform SLURM Postconfiguration Tasks” (page 108)
• “Perform LSF Postconfiguration Tasks” (page 109)
3.19.1 Perform SLURM Postconfiguration Tasks
If SLURM was configured, follow this procedure to finish the configuration process:
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.
