Events and event messages
When an event occurs in a storage system, an event message is recorded in the system’s event log and, depending on the system’s event
notification settings, can also be sent to users (using email) and host-based applications (using SNMP or SMI-S).
TIP:
A best practice is to enable notifications to be sent for events having severity Warning and higher.
Each event has a numeric code that identifies the type of event that occurred, and has one of the following severities:
•
Critical: A failure occurred that might cause a controller to shut down. Correct the problem
immediately
.
•
Error: A failure occurred that might affect data integrity or system stability. Correct the problem as soon as possible.
•
Warning: A problem occurred that might affect system stability but not data integrity. Evaluate the problem and correct it if necessary.
•
Informational: A configuration or state change occurred, or a problem occurred that the system corrected. No immediate action is
required. In this document, this severity is abbreviated as “Info.”
•
Resolved: The condition that caused an event to be logged has been resolved.
An event message might specify an associated error code or reason code, which provides additional detail for technical support. Error
codes and reason codes are outside the scope of this guide.

Event descriptions
This section describes event messages that may be reported during system operation and specifies any actions recommended in response
to an event.
This section describes all event codes that exist as of this publication. Depending on your system model and firmware version, some events
described in this document may not apply to your system. The event descriptions should be considered as explanations of events that you
do see. They should not be considered as descriptions of events that you should have seen but did not. In such cases those events
probably do not apply to your system.
In this section:
•
The term
disk group
refers to either a vdisk for linear storage or a virtual disk group for virtual storage.
•
The term
pool
refers to either a single vdisk for linear storage or a virtual pool for virtual storage.
Resources for diagnosing and resolving problems
