Monitoring the device event logs:
The ServeRAID adapters and controllers store information
concerning various events in the event logs. There are
four types of event logs: a device event log, a hard event
log, a soft event log, and a configuration event log. (See
“ServeRAID Configuration Program” on page 70 and
“ServeRAID Mini-Configuration Program” on page 94 for
information about the configuration event log.)
To view the hard, soft, or device event logs:
1. Select the adapter on the Main screen of the
Administration and Monitoring Program.
2. Select an event log button from the bottom of the
screen.
The Device Event Log contains event counters for each
attached physical device, as follows:
Ÿ
Parity Event - The ServeRAID adapter or controller
detected a parity event while transferring data on the
SCSI bus. A large number of parity events might
indicate a problem with the SCSI cable, connectors,
or terminators on the SCSI channel.
Ÿ
Soft Event - These events are detected by the SCSI
device and reported to the ServeRAID adapter or
controller through the SCSI Check Condition status.
Ÿ
Predictive Failure Analysis (PFA) - The device has
signaled the adapter or controller that it might fail in
the near future.
Ÿ
Hard Event - These events are detected by the
ServeRAID adapter or controller. The most likely
cause of a hard event is a problem with the SCSI
cabling, termination, or adapter seating. If one of
these is not the problem, replace the controller.
Ÿ
Misc Event - These miscellaneous events are
detected by the ServeRAID adapter or controller.
These events do not include parity, soft, PFA, or hard
events. The most likely cause of a miscellaneous
event is a cable, termination, or connector problem.
Note
Under normal operating conditions, the event logs will
contain entries that are not errors.
Monitoring the logical drive information:
You can monitor the logical drive information by clicking on
the desired logical drive button on the Main screen of the
Administration and Monitoring Program.
Descriptions of the information that appears on the Logical
Drive Information screen are as follows:
Logical Drive Number The number of the logical drive.
