4 Accessing the health of an HSP cluster
Hyper Scale-Out Platform Supporting and Troubleshooting
Monitoring alert conditions using the management
interfaces
Alert conditions are issues or negative circumstances that may require
customer support or administrative attention and/or corrective action.
Alerts are automatically removed by the HSP software once the underlying
issue that caused the alert condition is resolved.
The following summarizes the alert conditions that are raised for the various
HSP resources:
• cluster—Warning severity alert conditions are raised when the
administrator-defined high and low watermark thresholds for the
storage space of the cluster are out of the specified range.
• node—Warning severity alert condition is raised when a node is down or
is put in maintenance mode. Error severity alert condition is raised
when the run-state of a node is ERROR.
• disk—Error severity alert condition is raised when the run-state of a
disk is ERROR.
• ip-address—Warning severity alert condition is raised when the
run-state of an IP address is DOWN.
• file system—Warning severity alert conditions are raised when the
administrator-defined high and low watermark thresholds for file
system space are out of the specified range. Warning severity alert
condition is raised when the run-state of a file system is IMPAIRED.
Error severity alert condition is raised when the run-state of a file
system is ERROR.
Alert conditions are also raised when a node’s power supply, fan speed, and
CPU temperature sensors detect the following:
• Power supplies—Warning severity alert condition is raised when a
power supply cord on a node has been unplugged. Error severity alert
condition is raised when a power supply has failed.
• Sensors—Warning severity alert conditions are raised when the
thresholds that have been set for them have been exceeded.
Alert conditions include a resolution property describing the administrative
action that should be considered to correct or clear the alert condition.
The HSP software can be configured to send mail notifications to
administrators about alert conditions. You need to configure alert condition
notifications for each user account that you want notified of alert conditions
and you must set up a valid SMTP configuration in HSP. Consult the
documentation for the interface you are using to manage your HSP cluster
(API, CLI, or GUI) for details.
