APPENDIX B: Event Logs www.gateway.com

Overview
StorView has the ability to manage the events generated by the controller, SES
processors, 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)
The controller and StorView both maintain a set of event logs.
There are some differences and limitations between the controller’s 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.
You can disable enclosure event monitoring to reduce the polling that StorView
performs. This increases the performance that may be necessary in certain
applications. This is accomplished by de-selecting the
Enclosure Support
option in the ADVANCED SETTINGS window. Disabling this option stops
enclosure component monitoring, which is noted on the Main window by the
dimming of the enclosure rear view graphics and a notation above the graphic
stating
Enclosure Information Not Available . For more information, see
“Controller environmentals” on page 72 .
Important
If the Enclosure Support option is
disabled, e-mail notifications established
for those enclosure events do not occur.
StorView’s event log maintains 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. If the
Enclosure Support option is enabled, enclosure component
events are also logged.
The StorView server also performs a synchronization of its event log to the
controller log when the StorView server starts. Because the controller(s) can
continue to operate when StorView Server is shut down, the StorView log would
have missing events during this down period. StorView’s event synchronization
feature appends the log with the controller events that occurred while the
StorView server was shutdown.
