Appendix A. Disk Array Controller Log

The array controller continually monitors all components of the disk array, and logs any information that may be of helpful in
evaluating the performance and operation of the array. All aspects of array operation are logged, including:
•
changes to the operating status of the array
•
changes to the configuration of the array
•
performance data
•
port error statistics
Table 1 lists all event codes that can appear in the controller log event pages. The table also includes events that are not
logged, but can still generate SCSI sense data. Appropriate corrective action is included for all events that require it. Many
events are informational and require no action on the part of the user. The Suspected Component column lists the hardware
components potentially implicated by the event code.
