Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a method for automatically identifying and mounting a hard RAID device node according to an embodiment of the present invention is shown, where the method includes:
s11: and determining that any equipment node in the storage system is the current equipment node, and judging whether the product model information of the current equipment node is SAS card information.
It should be noted that, the execution subject of the method for automatically identifying and mounting a hard RAID device node according to the embodiment of the present invention may be a corresponding device, and the device may be disposed in a storage system. In the embodiment of the application, the hard RAID device nodes are queried and identified by traversing all the device nodes, specifically, it may be determined that any device node in the storage system is a current device node, and it is determined whether product model information of the current device node is SAS card information, where the SAS card information is a sign of an SAS card, such as information that is set according to actual needs, such as an identifier, an attribute, and the like. In the storage system, other device nodes are not realized through an SAS card but are directly inserted into corresponding hardware boards, and only hard RAID device nodes are realized through the SAS card, so that whether the device nodes are hard RAID device nodes or not needs to be determined by judging whether the device nodes are realized through the SAS card.
S12: and if the product model information of the current equipment node is SAS card information, judging whether the SAS card corresponding to the SAS card information belongs to the storage system, if so, determining that the current equipment node is a hard RAID equipment node, and mounting the hard RAID equipment node.
If the product model information of the current equipment node is SAS card information, the current equipment node is realized through an SAS card, so that the current equipment node can be preliminarily determined to be a hard RAID equipment node needing to be identified; in order to further determine whether the current device node is a hard RAID device node that needs to be searched, in this embodiment, it is further necessary to determine whether the identified SAS card information corresponds to the SAS card located on the storage system, that is, it is determined whether the SAS card information belongs to the storage system, so that a situation that an error occurs in acquiring the SAS card information is avoided. Therefore, the current equipment node is determined to be a hard RAID equipment node under the condition that the two judgments are both yes, mounting is realized, otherwise, the current equipment node is not the hard RAID equipment node, and therefore the accuracy of equipment node identification is improved through the double judgment steps.
S13: and if the product model information of the current equipment node is not the SAS card information, determining any equipment node which is not taken as the current equipment node in the storage system as the current equipment node, and returning to execute the step of judging whether the product model information of the current equipment node is the SAS card information.
If the product model information of the current equipment node is not SAS card information, the current equipment node is not realized through an SAS card, so that the current equipment node can be directly determined to be not a hard RAID equipment node device, and the step of judging whether other equipment nodes are hard RAID equipment nodes is returned. In addition, if the device node which is not used as the current device node does not exist and the hard RAID device node is not determined, the identification failure is determined and corresponding prompt information is output.
When judging whether equipment nodes in a storage system are hard RAID equipment nodes or not, the method is realized by judging whether the equipment nodes are realized based on an SAS card or not and whether the SAS card exists in the storage system or not corresponding to the equipment nodes; in order to avoid misreading of SAS card information, whether the SAS card corresponding to the SAS card information of the equipment node is positioned in the storage system or not is judged, so that the accuracy of hard RAID equipment node identification is further ensured; therefore, the technical scheme of the application can accurately identify and mount the hard RAID equipment nodes.
The method for automatically identifying and mounting the hard RAID device node provided in the embodiment of the present invention may further include, before determining whether product model information of the current device node is SAS card information:
and judging whether the equipment mark of the current equipment node is a corresponding mark of the hard RAID equipment node, if so, executing the step of judging whether the product model information of the current equipment node is SAS card information, otherwise, determining any equipment node which is not taken as the current equipment node in the storage system as the current equipment node, and returning to execute the step of judging whether the product model information of the current equipment node is SAS card information.
It should be noted that, when setting a hard RAID device node, a corresponding flag may be set for the hard RAID device node, so that whether the device node is a hard RAID can be determined by the flag. Therefore, the reason why the judgment of whether the judgment is implemented based on the SAS card is needed after the judgment of the flag is to avoid the situation that the flag is misread or the flag is added to other device nodes.
The method for automatically identifying and mounting the nodes of the hard RAID equipment provided by the embodiment of the invention can also comprise the following steps:
and if the product model information of the current equipment node is SAS card information, setting the status flag of the current equipment node as a flag indicating that the current equipment node is a preliminarily determined hard RAID equipment node.
It should be noted that, in order to quickly locate a corresponding device node when it is determined at a later stage that a device node whose product model information is SAS card information corresponds to whether a SAS card exists in the storage system, in this embodiment, a corresponding flag is added to current device information after it is determined that the product model information of the current device node is SAS card information, so as to improve implementation efficiency.
The method for automatically identifying and mounting the hard RAID device node provided in the embodiment of the present invention determines whether the SAS card information of the current device node corresponds to the SAS card belonging to the storage system, and may include:
the method comprises the steps of obtaining the WWID of the SAS card corresponding to the SAS card information of the current equipment node and the SAS card list of all SAS cards contained in a storage system, if the WWID corresponding to the current equipment node is the same as the WWID of any SAS card in the SAS card list, determining that the SAS card corresponding to the SAS card information of the current equipment node belongs to the storage system, and otherwise, determining that the SAS card corresponding to the SAS card information of the current equipment node does not belong to the storage system.
It should be noted that when determining whether the SAS card corresponding to the SAS card information belongs to the storage system, the WWID of the SAS card may be acquired, and since the WWID is a unique identifier corresponding to each SAS card, different SAS cards may be effectively distinguished, and then whether the SAS card belongs to the storage system is accurately determined, and the accuracy of identifying the hard RAID device node is further enhanced.
The method for automatically identifying and mounting the hard RAID device node according to the embodiment of the present invention may further include, after determining that the current device node is the hard RAID device node:
and recording the name, RAID level and RAID state of the hard RAID device node for query.
It should be noted that after determining the hard RAID device node, the relevant information of the hard RAID device node may be recorded for query as needed; specifically, the information of the hard RAID device node may include a name, RAID levels (including RAID0 to RAID5), and RAID states (normal operating states, abnormal operating states, and the like), and of course, other settings may be performed according to actual needs, and all of them are within the protection scope of the present invention.
The method for automatically identifying and mounting the nodes of the hard RAID equipment provided by the embodiment of the invention can also comprise the following steps:
and after the storage system is determined to be started, executing the step of determining any equipment node in the storage system as the current equipment node.
It should be noted that, in order to avoid a situation that a disk replacement or other reasons of the system cause that it is not possible to determine which identified hard RAID device node is, and thus cause a mounting error, in this embodiment, identification and mounting of the hard RAID device node are automatically achieved after the storage system is started up each time, so that mounting correctness is ensured, and a problem that client software, metadata and the like cannot be used is also avoided.
