14 Event Logs
Overview
StorView has the ability to manage the events generated by the controller, SES processor’s or SAF-TE
processes. StorView also has its own unique events that are related to the StorView server component
of the software. Events can be used to assist with troubleshooting, monitoring components, and
determining the status of hardware components, logical drives and arrays. The following event types
are logged:
• Drive and Array
• Controller
• Network communication (applicable to the host-based version only)
• Temperature and Voltage
• Fibre Loop and Bus (Drive and Host)
• Enclosure components
• StorView server (applicable to the host-based version only)
There are two event logs maintained: one set of log entries the controller maintains and one set
StorView maintains. There are some differences and limitations between the controller set of event
logs and StorView’s set of event logs. The differences include the type of events logged and in some
cases the ease of interpretation. StorView event logs provide a more user friendly language approach
to describing the event.
The controller’s maximum event log size is 4096 entries with the oldest events being overwritten as
the log reaches the size limit. Some repetitive events are appended to previous events, so entries
are not used up unnecessarily. The controller logs are managed by clicking the Controller icon and
accessing the Operation tab. From there you can export the controller logs to an external file or clear
the log entries.
Enclosure event monitoring can be disabled which reduces the polling that StorView performs thereby
increasing the performance that may be necessary in certain applications. This is accomplished by
deselecting the Enclosure Support option in the Advanced Settings window. Disabling this option
will stop enclosure component monitoring, which can be noted on the Main screen by the dimming
of the enclosure rear view graphics and a notation above the graphic stating “Enclosure Information
Not Available” see ”Controller Environmentals” beginning on page 71.
StorView’s event log will maintain the controller’s compilation of events and the software’s specific
events. The controller’s compilation of events include Controller Events (those unique to the RAID
Controller), Drive Events and Host Events, and if the Enclosure Support option is enabled, enclosure
component events.
 NOTE
If the “Enclosure Support” option is disabled, E-mail notifications established for those enclosure
events will not occur.
The StorView server will also perform a synchronization of its event log to the controller log when the
StorView server starts. Since the controller(s) can continue to operate when StorView Server is shut
down, the StorView log would have missing events during this down period. The event synchronization
feature of StorView will append the log with the controller events that occurred while the StorView
server was shutdown.
