Understanding SCSI Errors
The event log includes SCSI errors reported by SEPs and disk
drives on your system. If you see these errors in the event log, the
information below may assist you. For more information about
viewing the event log, see Displaying the Event Log on page 3-1.
Disk Errors
If a disk drive detects an error, it reports the error, which is
recorded in the event log. Figure 7-1 shows an example of a disk
drive-detected error.
Figure 7-1 Disk-Detected Error Example
Using the information in Table 7-3 and Table 7-4, you can see that
the example in Figure 7-1 is a medium error, unrecovered read
error—recommend reassignment.
Table 7-3 lists some of the most common SCSI sense key
descriptions (in hexadecimal). Table 7-4 lists the descriptions for
the most common sense codes (ASC) and sense code qualifiers
