In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two non-identical entities with the same name or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements does not include all of the other steps or elements inherent in the list.
In view of the foregoing, a first aspect of the embodiments of the present invention provides an embodiment of a disk management method. Fig. 1 is a schematic diagram illustrating an embodiment of a disk management method provided by the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
step S10, acquiring drive symbols and corresponding serial numbers of all disks in the storage system, and storing the drive symbols and the corresponding serial numbers in a first query list;
step S20, respectively acquiring names and corresponding serial numbers of all SAS cards and names and corresponding serial numbers of all RAID cards in the storage system, and sequentially acquiring drive symbols and corresponding serial numbers of all disks in each SAS card according to the serial numbers of all SAS cards and storing the drive symbols and the corresponding serial numbers in a second query list;
step S30, acquiring the drive letter and the corresponding serial number of each disk in each RAID card in turn according to the serial number of each RAID card, and storing the drive letter and the corresponding serial number into a third query list;
step S40, information in the second query list and the third query list is integrated into the first query list according to the serial numbers, discs which are not identified by the storage system are found out based on the integrated first query list, and the serial numbers of the discs which are not identified are marked to be distinguished from other identifiable discs in the integrated first query list;
and step S50, setting different styles for the distinguished unidentified disk and the identifiable disk on the interface of the storage system for management.
In the embodiment of the present invention, different patterns are respectively set for the distinguished unidentified disk and the distinguished disk on the interface of the storage system for management, and specifically, the method includes: two information interface display modes are constructed in an interface, the first mode is that a system cluster diagram with an equipment physical view is constructed aiming at an identifiable disk of a storage system, and functions of disk replacement, capacity expansion and contraction, disk positioning and the like are integrated in the interface to form an integrated disk management interface; and another loose interface display form is constructed aiming at the unidentifiable disk (namely the unidentified disk) of the storage system, and is displayed from the topological form of cluster-node-disk information, and the loose disk information display interface does not support the functions of disk replacement, capacity expansion, disk positioning and the like. The cluster disk information can be comprehensively classified and displayed by setting two different forms of reconstructed disk information interface display, so that the defect of the conventional classification management of unrecognizable disks in a storage system is overcome; the functions of disk management are integrated according to the characteristics of the identifiable disks and the unrecognizable disks, so that the functions are not influenced mutually, and the centralized classified management of the disks is realized.
RAID (Redundant Array of Independent Disks) is a technique that combines a plurality of Independent hard Disks (physical hard Disks) in different ways to form a hard disk group (logical hard disk), thereby providing higher storage performance than a single hard disk and providing data redundancy. The RAID card can support SAS and SATA hard disks to form RAID6\5\3\1\0\10 and the like.
SAS cards, also known as disk array cards, are used for RAID. The system is generally supported to be RAID0\1\10\1E or directly identify SAS hard disks, and is compatible with SATA hard disks (serial hard disks). Sas (serial Attached SCSI), which is a serial Attached SCSI, is a new generation of SCSI technology, and like the popular SATA hard disk, serial technology is used to obtain higher transmission speed and improve internal space by shortening connection lines. SAS is a completely new interface developed after parallel SCSI interfaces, which are designed to improve the performance, availability and scalability of storage systems and to provide compatibility with SATA hard disks.
In the embodiment of the invention, the drive symbols and the serial numbers of all the disks in the storage system are obtained and stored in the first query list, the drive symbols and the serial numbers of the disks belonging to the SAS card in the storage system are obtained and stored in the second query list, and the drive symbols and the serial numbers of the disks belonging to the RAID card are obtained and stored in the third query list, so that the identifiable disks and the unidentifiable disks in the storage system are completely obtained; the second query list and the third query list are integrated into the first query list according to the serial number of the disk, so that the disk which cannot be identified by the storage system can be found out; the recognizable disk and the unrecognizable disk of the storage system can be directly distinguished conveniently by marking the serial number of the unrecognizable disk; the identifiable disks and the unidentifiable disks are classified, arranged and displayed on the storage system interface, so that the disks can be comprehensively managed.

In some embodiments, finding disks not identified by the storage system based on the integrated first query list comprises: and taking the disk corresponding to the serial number which does not exist in the second query list and the third query list as the disk which is not identified by the storage system.
In the above embodiment, after the second query list and the third query list are integrated into the first query list according to the serial number, the recognizable disk and the unrecognizable disk of the storage system may be distinguished by querying the slot information. Specifically, if the serial number does not have corresponding slot position information in the integrated first query list, the disk corresponding to the serial number is an unidentifiable disk of the storage system; correspondingly, if some serial numbers in the integrated first query list have corresponding slot position information, the disks corresponding to the serial numbers are identifiable disks of the storage system. For the unidentifiable disk without the slot position information, the functions of disk replacement, capacity expansion, disk positioning and the like are not arranged on the system interface.
In some embodiments, obtaining drive signatures and corresponding serial numbers of all disks in the storage system comprises: and acquiring the drive letter and the corresponding serial number of all the disks in the storage system by using the ls tool and the smartcll tool.
