Replacing, moving, or adding hard drives 25
•
If the other controller is connected to one or more arrays of configured logical drives, the total number
of logical drives on the controller after the drives have been moved must not exceed the number of
logical drives that the controller supports. This number depends on the controller model and on the
controller firmware version.
•
If moving the logical volume to a hardware-based Smart Array controller that is connected to one or
more logical drives, confirm that the total number of logical drives does not exceed the number of
logical drives that the controller supports.
•
If moving the logical volume to an controller in another server, remove all physical drives from the other
server.
When all the conditions have been met, move the drives:
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 cache module.
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 ACU ("
" on page
After the drives have been moved, confirm that the total number of hard drives on the new controller does not
exceed the maximum number of supported hard drives for that controller model and firmware version.
Adding drives
You can add hard drives to a system at any time if you do not exceed the maximum number of drives that the
controller supports. You can then build a new array from the added drives.
If the hard drives that you intend to add to the system are configured into logical drives, you must meet certain
conditions before adding the hard drives to the system. For more information, see "Moving hard drives and
)."
Migrating hard drives to an optional Smart Array
controller
1.
Install the optional controller. To install an optional Smart Array controller, see the HP Smart Array
Controllers for HP ProLiant Servers User Guide on the HP website
