Embodiment Construction

[0040] The principles of the disclosure will be described below with reference to several example embodiments illustrated in the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that these embodiments are only described to enable those skilled in the art to better understand and implement the present disclosure, but not to limit the scope of the present disclosure in any way.

[0041] figure 1 is a schematic diagram of a physical drive array according to an embodiment of the disclosure. Such as figure 1 As shown, the array of the present disclosure includes a plurality of physical drives, and a plurality of slots respectively corresponding to each physical drive (ie, slot 0, ... slot 4 ... slot n). Each physical drive is capable of making an electrical connection (for data transfer and power transfer) to a slot. figure 1 The physical drive array shown in includes system drives (drives 0 th...

Abstract

Embodiments of the present disclosure provide a method and apparatus for handling the movement of a physical drive by generating a provision drive for a physical drive that is moved; establishing a connection from the provision drive to the physical drive; and updating the provision drive via the connection according to location information of the physical drive.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of storage devices, and more particularly, to a method and apparatus for handling movement of physical drives. Background technique [0002] Before releasing the storage device VNX2, EMC 2 Released block storage device products such as VNX and AX / CX. However, block storage devices such as VNX, AX / CX do not support the movement of user drives and system drives, in other words, they require all drives to be fixed in their corresponding slots, and only when the drive fails or is damaged Only then is it allowed to replace it with a new drive. [0003] at EMC 2 In the VNX2 array, it is no longer required that the physical drives in the system must be bound in specific slots, thus making "portable drives" one of its characteristics. In other words, physical drives with bound LUNs and disk groups (Raid groups) (Raid groups mainly provide data reconstruction, verification, and Raid algorithms) can b...
