HP Smart Array P731m Controller - Manual (Page 28)

Drive procedures 28
2. Power down the system.
3. Move the drives.
4. Power up the system.
5. Observe the POST messages:
o If a 1785 POST message appears, the drive array did not configure properly. Continue with step 6.
o If a 1724 or 1727 POST message appears, drive positions were changed successfully and the
configuration was updated. Continue with step 7.
6. If the array did not configure properly, do the following:
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.
7. Verify the new drive configuration by running HP SSA (" Configuring an array " on page 16 ).
Adding drives
You can add drives to a system at any time, if 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.
If the drives that you intend to add to the system are already configured into logical drives, you must meet
certain conditions before adding drives to the system. For more information, see "Moving drives and arrays
(on page 27 )." When you have successfully added the drives, reset the server so that the controller can
recognize the logical drives.
To perform an array capacity expansion, use HP SSA. If the system uses hot-pluggable drives and HP SSA
runs 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 HP Smart Storage Administrator User
Guide on the HP website ( http://www.hp.com/go/smartstorage/docs ).
