Diagnosing Disk Faults
To determine which disk failed, you can view the FMA fault error log, use
fmdump
command, or open the system cover to look for illuminated LEDs. If you use the
fmdump
command to isolate a disk, you should also open the system cover and look
for amber LEDs. The following is an example of the
fmdump
command you can use
to display disk faults.
The following is an example of information that is displayed when a disk fault is
detected and the
fmdump
command is used.
Based on the information displayed, you can determine which disk failed and the
attachment point.
For more information, see the
fmdump
(1M) man page.
