Moving Hard Drives And Arrays - HP Smart Array B140i User Manual

Moving hard drives and arrays

When moving drives, observe the following guidelines:
•
You can move drives to other ID positions on the same array controller.
•
You can move drives from a B-series controller to a P-series controller.
CAUTION: Back up all data before moving drives from a B-series controller to a host bus
adapter. Otherwise, data will be lost.
•
You can move drives from a B-series controller to a host bus adapter. However, any volume
configuration will not be migrated to the new HBA.
•
You cannot move drives from a P-series controller to a B-series controller.
Observe the following conditions for moving drives:
•
Power down the server.
•
If moving the drives to a different server, confirm that the new server has empty bays to
accommodate all the drives simultaneously.
•
Confirm that the array has no failed or missing drives.
•
Confirm that no spare drive in the array is acting as a replacement for a failed drive.
•
If moving the drives to a different server, confirm that the new server has the latest system ROM and
drivers. For more information, see the Hewlett Packard Enterprise website
(http://www.hpe.com/support/hpesc).
Observe the following conditions for moving an array to another controller:
•
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:
Back up all data before removing any drives or changing configuration. This step is required if you
1.
are moving data-containing drives from a controller that does not have a cache module.
Power down the system.
2.
Move the drives.
3.
Power up the system.
4.
Observe the POST messages:
5.
If a 1785 POST message appears, the drive array did not configure properly. Continue with step
o
6.
If a 1724 or 1727 POST message appears, drive positions were changed successfully and the
o
configuration was updated. Continue with step 7.
If the array did not configure properly, do the following:
6.
Power down the system immediately to prevent data loss.
a.
Return the drives to their original locations.
b.
Replacing, moving, or adding hard drives 20
