Disk Channel Errors
Disk channel errors are similar to disk-detected errors, except they
are detected by the controller, instead of the disk drive. Some disk
channel errors are displayed as text strings, others are displayed as
hexadecimal codes.
Figure 7-2 shows a disk channel error displaying the hexadecimal
code. Table 7-5 lists the error code descriptions. Most disk channel
errors are informational because the controller issues retries to
correct any problem. Errors that cannot be corrected with retries
will result in another critical event describing the affected disk
array (if any).
