Rebuilding logical drives after disk failures 9–67
When the disks have been replaced, the error messages shown above may continue to be generated; this
is because the logical drive needs to be rebuilt. You can rebuild the logical drive using the
hpacucli
utility
(on one of the servers to which the array is attached), as described here. In the example shown here, array
42 is the array where the logical drive failed and the disks have been replaced. The
ld all show
command in the
hpacucli
utility shows the status of the logical drives on the array as
Failed
. The
modify reenable
command is used to change the status of the logical drives to
OK
.

When the logical drive has been rebuilt, it can be accessed again. There is a small possibility that you may
then be able to recover some of the original data from the LUN associated with the logical drive by using
the MPI Lustre repair utility. For information on using this utility, see Section 9.26.5.
