HP XC System Software Release Notes for Version 3.0

14.3.1 System Event Logs
This new functionality was delivered to your HP XC system through the PK01 patch for Version
3.0.
Each hardware platform provided by HP supplies an event logging mechanism to capture
platform-specific events to track hardware states and changes. Information in the system event
log (SEL) varies, but it typically contains information including, but not limited to, the following:
• Memory ECC errors
• Power supply failures
• Voltage problems
Event logs are stored by the firmware and can become full over time. Some hardware models
require regular maintenance to clear the logs to avoid losing critical events. In addition, errors
that indicate failure or pending failure of a component need to be brought to the operator's
immediate attention.
The HP XC system event log functionality provides complete management of all log types of
supported HP platforms. Log information is regularly read and archived, and the information
is used to generate Nagios alerts when applicable. Logs that approach a critical size are cleared
to prevent event loss.
Event logs are typically accessed through the management port requiring
platform/protocol-specific user authentication as well as network access to the console port
(cp-nxxx, where nxxx is the node number).
System event log history is captured in the /hptc_cluster/adm/logs/sel/sel-nxxx.log
file where nxxx represents the name of the individual node.
System event logs are managed by the standard logrotate functionality. For more information
on this utility, see logrotate(8).
14.3.2 Configuring System Event Logging
This new functionality was delivered to your HP XC system through the PK01 patch for Version
3.0.
System event log and hardware sensor information is gathered using the input interface for
platforms without an iLO management port. Some platforms require additional user name and
password setup to allow access to the BMC/IPMI connection on the console port. In addition,
depending on how your head node is attached to the network, additional password setup may
be required.
On HP XC systems whose head node is either an HP CP6000 HP Integrity system or an HP
CP4000 HP ProLiant system, you can only obtain the sensor and system event log information
remotely.
See “Required Task: Configure the BMC Password On Itanium Systems” (page 32) for instructions
to configure the BMC password on HP Integrity systems.
14.3.3 Modifying System Event Log Rotation and Nagios Alerts
This new functionality was delivered to your HP XC system through the PK01 patch for Version
3.0.
You can use the logrotate command to change the rotation of the system event logs and the
rules for Nagios alerts.
In this release (with all patches installed), Nagios is able to alert you with power, memory,
voltage, and automatic system recovery (ASR) messages.
Nagios alert rules are defined in the /opt/hptc/nagios/etc/selRules file. Edit this file if
you want to modify the alert rules.
