System Management
Responding to the Alert Monitor
Alerts warn you when Storage Center requires attention. The current status of the Storage
Center is indicated by the color of the System Status icon in the top-right corner of the
System Manager software.
Alert indicators
Alerts occur in various types depending upon the area of the Storage Center affected. The
type of the alert is indicated by the icon that appears before the alert message.
• Red (Critical): The System Status icon is red when an alert exists that has a status
of Down, Critical, or Emergency. When the System Status icon is red, this indicates a
condition that requires immediate attention.
• Yellow (Warning): The System Status icon is yellow when an alert exists that has
a status of Degraded or Unavailable. This indicates a condition of which you should be
aware, but which does not require immediate attention.
• Green (Normal): The System Status icon is green when no alerts exist, when the
only alerts that exist are to inform you. The System Status icon returns to green when
all alerts higher than Inform are acknowledged.
Alert Categories
• Alert: This category contains normal alerts. These alerts represent current issues
present on the Storage Center. They are also being actively monitored by the system,
and will clear themselves automatically should the situation that has caused them
corrects itself. Once an alert of this type becomes cleared, a record that it occurred can
be found under the Alert History category.
• Indication: This category contains alerts that are for informational purposes only. These
alerts exist to warn you about a condition on the Storage Center that may require direct
user intervention to correct.
• Maintenance: This category contains any alerts that occur while the Storage Center's
Operation Mode is set to Install, Maintenance, or PreProduction. This category exists to
isolate these alerts from alerts that occur during normal operation.
• History: This category contains a history of the normal alerts that appeared and were
cleared automatically. This category exists to allow you to keep a record of any past
conditions that have occurred on the Storage Center.
Alert Status
Down: Alerts with an alert status of Down indicate that an item on the Storage Center is
down and not currently operational.
Critical: Alerts with an alert status of Critical indicate that an item on the Storage Center is
in a critical state and may be nearing failure.
Emergency: Alerts with an alert status of Emergency indicate that an item on the Storage
Center requires immediate attention in order to remain operational.
Degraded: Alerts with an alert status of Degraded indicate that an item on the Storage
Center is currently operating in a degraded mode. Items in this condition may operate in
degraded mode indefinitely, but are not functioning to their full capability.
