Therefore, the disk management method in the storage system can automatically identify the newly added disk in the storage system and acquire the effective information of the newly added disk, including the disk information and the disk array information, and reasonably allocate the newly added disk to the storage system according to the disk array information of the disk.
The following describes the disk management method in the storage system of this embodiment in detail. The method for managing the disk in the storage system provided by the embodiment comprises the following steps:
s10: the change of the magnetic disk in the storage system is monitored, and a new magnetic disk is identified.
The change of the disk equipment in the storage system is monitored in real time, and when a new disk is added, the change can be found in time. There may be one or more disks added at a time.
S11: and scanning the newly added disk to obtain disk information and disk array information of the newly added disk.
And scanning the newly added disk to acquire disk information and disk array information, wherein the disk information comprises hardware information and storage information of the disk, and the disk array information refers to information of a disk array to which the disk belongs.
S12: and comparing the disk array information of the newly added disk with the original disk array information of the storage system, and configuring the newly added disk into the storage system according to the comparison result.
Comparing the disk array information of the newly added disk with the disk array information in the storage system, wherein the comparison result specifically comprises the following conditions:
in the first case: the disk array of the newly added disk exists in the storage system.
In the second case: the disk array of the newly added disk does not exist in the storage system.
In the third case: the newly added disk does not have disk array information.
In the first case, when the disk array of the newly added disk exists in the storage system and it is detected that the disk array corresponding to the newly added disk is in a failure or degraded state in the storage system, the newly added disk is added to the disk array and the disk array is recovered. Referring to fig. 2, for the newly added disk 2, if the disk array corresponding to the newly added disk 2 exists in the storage system, but is in a degraded state, the newly added disk 2 is added to the corresponding disk array in the system, and the disk array is repaired to be a normal disk array.
When the disk array of the newly added disk exists in the storage system and the disk array corresponding to the newly added disk is detected to be in a normal state in the storage system, initializing the newly added disk, and setting the newly added disk as a free disk to be configured in the storage system. Referring to fig. 2, for the newly added disk 1, if there is a corresponding disk array in the storage system and the disk array is in a normal state, the newly added disk 1 is initialized and set as a free disk.
In the second case, when the disk array of the newly added disk does not exist in the storage system, comparing the disk array information of the newly added disk with the disk array information of other newly added disks, if the comparison shows that other newly added disks with the same disk array information exist in the newly added disk, forming the disk array by all the newly added disks with the same disk array information, and configuring the newly added disk with the same disk array information and the affiliated disk array into the storage system together. Referring to fig. 2, for the newly added disk 3, the corresponding disk array does not exist in the storage system, but the newly added disk includes three newly added disks 3 with the same array information, the three newly added disks 3 form a disk array, and all the disk arrays 3 and the disk arrays to which the disk arrays belong are added to the storage system.
And if the comparison shows that other newly-added disks with the same disk array information do not exist in the newly-added disks, initializing the newly-added disks, and setting the newly-added disks as free disks to be configured in the storage system. As shown in fig. 2, for the newly added disk 4, the disk array corresponding to the newly added disk does not exist in the storage system, and the newly added disk having the same disk array information as the newly added disk does not exist in the newly added disk, the newly added disk 4 is initialized and configured as a free disk to be added to the storage system.
In a third case, if the newly added disk does not have the disk array information, the newly added disk is initialized and set as a free disk to be configured in the storage system. As shown in fig. 2, for a new disk without disk array information (corresponding to a blank box in the new disk in the figure), the new disk is added to the storage system for initialization and configured as a free disk.
For the existing storage system, when a plurality of disks are added at one time, only the information of each disk can be identified one by one, and a disk array formed by a plurality of new disks or a disk originally belonging to a certain disk array in the system cannot be effectively identified. If a new disk with a complete disk array or originally belonging to the system disk array is desired to be effectively identified, technicians can only manually configure the information of the disk array into the system, which is not favorable for the recovery of degraded or failed arrays in the system and the migration of the whole disk array between storage systems.
In the disk management method in the storage system of this embodiment, when a plurality of new disks are added to the storage system at one time, the newly added disk can be automatically identified, the disk information and the disk array information of the newly added disk can be acquired, and the newly added disk can be reasonably added to the storage system according to the disk array information.
