Event Severities
The storage system generates events having three severity levels:
■ Informational – A problem occurred that the system corrected, or a system
change has been made. These events are purely informational; no action required.
■ Warning – Something related to the system or to a virtual disk has a problem.
Correct the problem as soon as possible.
■ Critical – Something related to the system or to a virtual disk has failed and
requires immediate attention.
There are a number of conditions that trigger warning or critical events and can
affect the state of status LEDs.
Viewing the Event Log
Some of the key warning and error events included in the event log during operation
include the following:
■ Disk detected error
■ Disk channel error
■ Drive down
■ Virtual disk critical
■ Virtual disk offline
■ Temperature warning
■ Temperature failure (this leads to a shutdown which is also logged)
■ Voltage warning
■ Voltage failure (this leads to a shutdown which is also logged)
The event log stores the most recent events with a time stamp next to them with
one-second granularity.
Note – If you are having a problem with the system or a virtual disk, check the
event log before calling technical support. Event messages might enable you to
resolve the problem.
You can save the event log to a file; see “Saving Log Information to a File” on
page 192.
