Chapter 4: Events And Event Messages; Event Descriptions - Dell PowerVault ME5 Series Owner's Manual

When an event occurs in a storage system, an event message is recorded in the system event log. Depending on the event
notification settings of the system, the event message can also be sent to users using email, and to host-based applications
using SNMP.
NOTE: A best practice is to enable notifications to be sent for events having a 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 the event messages that may be reported during system operation and specifies any actions
recommended in response to an event.
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.
