Increase the capacity of an existing array by adding currently existing unassigned drives to it. Any drive that you want to add must meet the following criteria:
It must be an unassigned drive.
It must be of the same type as existing drives in the array example, NVMe SSD, SAS HDD, SAS SSD, SATA HDD, or SATA SSD.
It must have a capacity no less than the capacity of the smallest drive in the array.
This operation uses the Modify Array option in the HPE MR Storage Administrator user interface. This feature is supported when there is a single logical drive
configured in the array.
Replace driveReplace drive
The replace drive operation allows you to replace failed physical drives in the array with healthy physical drives. The original array and logical drive numbering is
unaffected after the replacement. Note the following conditions and restrictions for the Heal Array operation:
The replacement physical drives and the original drives must be the same interface type such as SAS or SATA as the original drives.
The operation is available only if enough unassigned physical drives of the correct size are available.
The array is not transforming for example, rebuilding to a spare.
The array has a working cache, making it capable of transformation.

Transportable controllerTransportable controller
The controller firmware supports a transportable battery-backed cache memory to recover the data from a faulty server. This transportable controller recovers
from a faulty server by moving the entire controller to a new replacement server.
In this design, the controller firmware assumes that the new server has the same configuration. That is, the configuration includes the same server generation and
family, and logical drives are migrated to the new target server to facilitate cache flush when the data is restored.
Expand volumeExpand volume
The expand volume feature allows the capacity of a logical drive to be expanded by using unused space on existing disks, without requiring a reboot. Extending a
