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: 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. Soft Event - These events are detected by the SCSI device and reported to the ServeRAID adapter or controller through the SCSI Check Condition status. Predictive Failure Analysis (PFA) - The device has signaled the adapter or controller that it might fail in the near future. 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. 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. Netfinity 5500 M20 - Type 8662 117
