15.3.5 Forcing a Logical Drive with Multiple Drive Failures Back Online

If multiple disk drives fail in the same logical drive, you may be able to recover the data by forcing the logical drive back online. For instance, if two drives fail in a RAID 5, forcing it online may allow you to access the data, depending on which disk drives failed.
CAUTION: This procedure is not guaranteed to successfully recover your logical drive. The surest way to recover your data is to restore the failed logical drive from backup.

To force a logical drive online:

  1. In the Enterprise view, select the failed logical drive (see Identifying a Failed or Failing Component).
  2. On the ribbon, in the Logical Device group, click Force Online.
  3. Click Force, then click OK.
