HP Smart Array P700m Controller - Manual (Page 25)

Replacing, moving, or adding hard drives 25
• The controller is not running capacity expansion, capacity extension, or RAID or stripe size
migration.
• The controller is using the latest firmware version (recommended).
If you want to move an array to another controller, all drives in the array must be moved at the same time.
When all the conditions have been met:
1. Back up all data before removing any drives or changing configuration. This step is required if you
are moving data-containing drives from a controller that does not have a battery-backed cache.
2. Power down the system.
3. Move the drives.
4. Power up the system. If a 1724 POST message appears, drive positions were changed successfully
and the configuration was updated.
If a 1785 (Not Configured) POST message appears:
a. Power down the system immediately to prevent data loss.
b. Return the drives to their original locations.
c. Restore the data from backup, if necessary.
5. Verify the new drive configuration by running ORCA or ACU (" Configuring an array " on page 11 ).
Adding drives
You can add hard drives to a system at any time, as long as you do not exceed the maximum number of
drives that the controller supports. You can then either build a new array from the added drives or use the
extra storage capacity to expand the capacity of an existing array.
To perform an array capacity expansion, use ACU. If the system is using hot-pluggable drives and ACU is
running in the same environment as the normal server applications, you can expand array capacity
without shutting down the operating system. For more information, see the Configuring Arrays on HP
Smart Array Controllers Reference Guide.
