When automatic data recovery has finished, the online LED of the replacement drive stops blinking
and begins to glow steadily.
Failure of another drive during rebuild
If a non-correctable read error occurs on another physical drive in the array during the rebuild
process, the Online LED of the replacement drive stops blinking and the rebuild abnormally
terminates. If this situation occurs, restart the server. The system might temporarily become
operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive,
replace it, and restore data from backup.
Handling disk drive failures
If the controller was configured with hardware fault tolerance, complete the following steps after
a disk drive failure:
1.
Determine which physical drive failed. On hot-plug drives, an amber drive failure LED
illuminates.
2.
If the unit containing the failed drive does not support hot-plug drives, perform a normal
shutdown.
3.
Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug
drives, after you secure the drive in the bay, the LEDs on the drive each flash once in an
alternating pattern to indicate a successful connection. The online LED flashes, indicating that
the controller recognized the drive replacement and began the recovery process.
4.
Power up the server, if applicable.
5.
The controller reconstructs the information on the new drive, based on information from the
remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives,
the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.
iSCSI module diagnostics and troubleshooting
Diagnostic information is also available through HP P6000 Command View and the CLI event logs
and error displays. This section describes diagnostics.
iSCSI and iSCSI/FCoE diagnostics
The iSCSI and iSCSI/FCoE self test status and operational status are indicated by the MEZZ LED
as shown in
