Adding Hot Spare Drives

Note: Start a consistency check immediately after the rebuild is
complete to ensure data integrity for the virtual drives.
See Section 10.2, "Running a Consistency Check,"
information about checking data consistency.
2. Scenario #2: If some of the drives in a configuration are removed and
re-inserted, the controller considers the drives to have foreign
configurations.
Import or clear the foreign configuration. If you select Import,
automatic rebuilds will occur in redundant virtual drives.
Note: Start a consistency check immediately after the rebuild is
complete to ensure data integrity for the virtual drives.
See Section 10.2, "Running a Consistency Check,"
information about checking data consistency.
3. Scenario #3: If all of the drives in a virtual drive are removed, but at
different times, and re-inserted, the controller considers the drives to
have foreign configurations.
Import or clear the foreign configuration. If you select Import, all
drives that were pulled before the virtual drive became offline will be
imported and then automatically rebuilt. Automatic rebuilds will occur
in redundant virtual drives.
4. Scenario #4: If the drives in a non-redundant virtual drive are
removed, the controller considers the drives to have foreign
configurations.
Import or clear the foreign configuration. No rebuilds will occur after
the import operation because there is no redundant data to rebuild
the drives with.
Hot spares are drives that are available to automatically replace failed
drives in a RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, or RAID 60
virtual drive. Dedicated hot spares can be used to replace failed drives
in a selected drive group only. Global hot spares are available to any
virtual drive on a specific controller.
To add a dedicated or global hot spare drive, follow these steps:
