HP Smart Array B110i SATA RAID-Controller - Manual (Page 17)

Replacing, moving, or adding hard drives 17
You might be able to enable a recently failed drive temporarily by cycling the server power. To cycle the
server power:
1. Power down the server.
2. Remove the replacement physical drive (the one undergoing a rebuild), and then reinstall the drive
that it is replacing.
3. Power up the server.
If the newly failed drive is operational, do the following:
1. Back up any unsaved data.
2. Remove the original drive that was being replaced, and then reinsert the replacement physical drive.
The rebuild process restarts automatically.
3. When the rebuild process has finished, replace the newly failed drive.
If the newly failed drive has not recovered, do the following:
1. Remove the original drive that was being replaced, and then reinsert the replacement physical drive.
2. Replace the newly failed drive.
3. Restore data from the backup.
Moving hard drives and arrays
You can move drives to other ID positions on the same array controller. You can also move a complete
array from one controller to another.
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 HP website (
http://www.hp.com/go/support ).
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 HP Smart Array B110i SATA RAID 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.
