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.
The embodiment of the invention discloses a node topology information determination method, a device, equipment and a computer readable storage medium based on a storage network, which are used for rapidly determining the topology information of a storage node according to the interconnection information of an FC port.
Referring to fig. 1, a method for determining node topology information based on a storage network according to an embodiment of the present invention includes:
s101, obtaining interconnection information among FC ports of nodes in a storage network;
it should be noted that the interconnection information between the FC ports refers to information communicated between the FC ports, for example: if P1 and P2 respectively indicate port numbers of FC ports, the interconnection information (P1 and P2) indicates that the P1 port and the P2 port are connected. For nodes in a storage network, each node may have multiple FC ports, and the interconnection information only indicates interconnection conditions between different FC ports, and it is not possible to know whether different ports belong to the same node, so that the interconnection conditions between nodes cannot be directly reflected by the interconnection information, and topology information of the nodes cannot be directly obtained according to the interconnection information. By the node topology information determining method, the storage end can analyze the FC port interconnection information identified by storage to obtain the topology structure information of the FC network where the storage is located. According to the analyzed result, the user can visually see the actual interconnection information based on the network node.
S102, determining an independent sub-network of the storage network according to the interconnection information; each independent sub-network is composed of FC ports and switches with interconnection relation;
in the present application, since the interconnection information describes the communication status of different FC ports, based on the communication status of each FC port, an independent sub-network of the storage network can be obtained, and the number of the independent sub-networks may be 1 or more, and is determined mainly based on the port communication status described in the interconnection information. And, since the reality of network connection is that one port can only be directly connected with another port, just like a line has only two vertices. If multiple ports are reachable from one port, there must be a bifurcation between the ports, and the switch must exist at the intersection of the bifurcation. For example: there is interconnection information (P1, P2) and (P1, P3), and it can be seen that P1 can communicate with both P2 and P3, i.e.: the port P1 can reach the ports P2 and P3, and in the independent sub-networks composed of P1, P2 and P3, the cross point between P1, P2 and P3 is necessarily existed, and the cross point is the position where the switch exists. In the present application, therefore, the independent sub-networks are formed by FC ports and switches having an interconnecting relationship.
S103, aggregating and replacing FC ports belonging to the same node in the independent sub-networks by utilizing the corresponding relation between each node and the FC ports to obtain the actual topology information of each node.
It should be noted that, in this scheme, the independent sub-networks included in the storage network may be analyzed according to the interconnection information of the FC ports acquired by the storage end, and the FC ports are divided into corresponding sub-independent sub-networks, so as to generate the attribution information of the ports and the network. After the network analysis is finished, the ports are aggregated by using the corresponding relation between the stored nodes and the ports, and are abstracted into nodes, so that the node-based topology information is generated. S103 is explained here by taking one case: if the independent sub-network comprises: p1 is connected to P2 and P3 through switches, and P1 and P2 have a corresponding relationship with node 1, and P3 has a corresponding relationship with node 2, then in this independent sub-network, P1 and P2 are aggregated and replaced by node 1, and P3 is replaced by node 2, then the actual topology information of the node corresponding to the independent sub-network is generated as follows: and the node 1 and the node 2 are interconnected in a topological relation.
Further, in this application, after obtaining the actual topology information of each node, the method further includes: comparing the actual topology information with planning network topology information, and judging whether the actual topology information is the same as the planning network topology information; and if the link failure information is different, generating failure link prompt information.
It should be noted that, after the actual topology information is obtained, the actual topology information may be compared with the preset planning network topology information for analysis, whether the actual topology information is consistent with the planning topology information is judged, if not, a faulty link may exist in the network, and at this time, a faulty link prompt message may be generated, so as to prompt a user to store a fault that may exist in the network, thereby effectively assisting the user in analyzing and processing the network connection problem.
Therefore, the scheme can automatically realize the work of manual analysis and manual investigation originally, improve the analysis efficiency and avoid manual omission. According to the analysis result, the user can quickly master the actual network topology information, quickly find the problem, locate the problem and solve the problem.
Based on the foregoing embodiment, in this embodiment, the determining, in the step S102, an independent sub-network of the storage network according to the interconnection information specifically includes the following steps:
s11, selecting unanalyzed initial interconnection information from the interconnection information;
s12, setting the interconnection relationship of the two FC ports of the initial interconnection information in the initial sub-network, and taking the FC ports with the interconnection relationship as identified ports;
in this embodiment, when an independent sub-network is established, it needs to be determined according to the interconnection relationship between the ports, and if there is interconnection information in two ports, the two ports are considered to have the interconnection relationship. For example: assume that the unanalyzed FC port interconnection information constitutes a set S1; an initial interconnection information (P1, P2) is selected from the set S1, and the initial interconnection information includes port numbers of two FC ports that can be identified to each other, P1 and P2.
Here, for better illustration of the process of establishing an independent subnetwork, assume P1, P2 are two points on the horizontal axis of the planar coordinate system, P1 is at the origin of the coordinate system, and P2 is a point sufficiently far from P1 on the horizontal axis, which can be considered as the initial subnetwork N1 of an independent subnetwork. In this embodiment, the interconnection information selected from the interconnection information is referred to as analyzed interconnection information, the interconnection information not selected from the interconnection information is referred to as unanalyzed interconnection information, and similarly, the FC port in the selected interconnection information is referred to as an identified port, for example: the initial interconnection information (P1, P2) selected from the interconnection information is analyzed interconnection information, and P1, P2 are identified ports.
S13, selecting unanalyzed target interconnection information from interconnection information, wherein one FC port of the target interconnection information is an identified port;
s14, updating the port interconnection relation of the initial sub-network according to the target interconnection information, and setting a switch at the intersection of the port interconnection relation;
it should be noted that, in the process of establishing an independent sub-network, it is necessary to select unanalyzed interconnection information from interconnection information to update the initial sub-network, and in the process of selecting, it is necessary to select interconnection information including an identified port. Moreover, the process of updating the port interconnection relationship of the initial sub-network according to the target interconnection information and setting a switch at the intersection of the port interconnection relationship may specifically include: adding the interconnection relationship between the identified port and the unidentified port in the target interconnection information in the existing port interconnection relationship of the initial sub-network, and setting a switch at the newly added cross point of the port interconnection relationship; judging whether a target switch exists in the existing port interconnection relationship of the initial sub-network, wherein the port corresponding to the target switch and the unidentified port in the target interconnection information have interconnection relationship; and if so, merging the newly added switch and the target switch.
It will be appreciated that since one port needs to communicate with a plurality of ports through a switch, a switch needs to be provided at each intersection of the original sub-networks, and since a switch can achieve communication of one port with a plurality of ports, satisfactory switches can be merged. For example: the existing port interconnection relationship of the initial sub-network is as follows: if the switch H1 exists, the switch H1 realizes the communication between the P1 and the P2 and the P3, and the selected target interconnection information is (P1, P4), the interconnection relationship between the identified port P1 and the unidentified port P4 is added in the existing port interconnection relationship, and the switch H2 for realizing the interconnection between the P1 and the P4 is generated at the newly added cross point of the port interconnection relationship; at this time, it is necessary to check whether there is a target switch, which is a switch having an interconnection relationship between a corresponding port and an unidentified port P4 in the target interconnection information (P1, P4), and in the existing port interconnection relationship, there is a P3 port in the switch H1, and at this time, it is necessary to determine whether the P3 port of the switch H1 has an interconnection relationship with the unidentified port P4 in the target interconnection information (P1, P4) from the interconnection information, and if there is, H1 and H2 may be merged to be a switch.
Here, based on the above process of establishing the N1 network, a specific case is listed to explain the process of S13-S14:
1) selecting target interconnection information containing identified ports in the N1 network from the set S1, where the target interconnection information is (, P1) or (, P2), and represents an unidentified port, and the target interconnection information is (P1, P3);
2) selecting a cross point of an intermediate position between an entity (currently, P2) nearest to P1 in a P1 and N1 network as H1, wherein H1 exists in the network in the role of a switch, the P3 is interconnected with the P1 through H1, and due to the characteristics of the FC network, it can be determined that an interconnection message (P3, P2) exists in S1, and P3 and P2 are also interconnected through H1;
it should be noted that, since the present application abstracts the positions of P1 and P2 into a coordinate system, for convenience of calculation and understanding, the position of the switch H1 is selected to be an intermediate position on a straight line segment defined by two points P1 and P2, and of course, the position of H1 may be selected to be an arbitrary position on a straight line segment defined by two points P1 and P2, and is not particularly limited herein.
3) Continuing to extract a piece of target interconnection information containing the identified ports in the N1 network from the set S1, i.e., (# P1) or (# P2) or (# P3), where the interconnection information is assumed to be (P1, P4);
4) selecting a point in the middle position between the P1 and an entity (currently, H1) in the N1 network, which is closest to P1, as a switch H2, and assuming that P4 is interconnected with P1 through H2;
5) searching whether interconnection information exists from the set S1 (P3, P4), if yes, considering H2 as a target switch, H2 can be merged with H1, and if not, considering H2 as an entity independent of H1;
it should be noted that if P3 cannot communicate with P4, configuration is made on H2, which limits communication between P3 and P4, and is considered to be independent H2 in form. If P3 can communicate with P4, then H2 is formally considered to be H1, although two may be independent in practice, but one in business performance, which cannot be determined only by interconnection information.
S15, judging whether target interconnection information with an identified port exists in the interconnection information; if so, continue to S13; if not, go to S16;
s16, taking the final initial sub-network as an independent sub-network, deleting the analyzed interconnection information from the interconnection information, and deleting the identified port;
s17, judging whether the interconnection information contains the unanalyzed interconnection information; if yes, continuing to execute S11 to identify other independent sub networks in the interconnection information; if not, the flow ends.
It can be understood that, after the target interconnection information is analyzed, it is necessary to continue to obtain target interconnection information (Pm, Pn) related to the identified ports in the N1 network from the set S1, where Pn is the identified ports in the N1 network, and Pm is the ports that are not identified in the N1 network, and continue to perform S13-S14 to perform subnet aggregation until the target interconnection information related to the identified ports in the N1 network does not exist in S1, and the N1 network topology identification is completed, so as to obtain an independent subnet, and remove all the identified interconnection information from the set S1; if the interconnection information has unanalyzed interconnection information, the process continues to S11 to identify a new subnetwork until the set S1 becomes an empty set, the storage network topology identification is completed, and the corresponding information of the port and the network is generated.
It should be noted that, in the present application, storage node information needs to be acquired, where the information includes FC port number information of each storage node, and then host port number binding information already configured by the storage system is acquired, where the information includes port number host aggregation information already configured, that is: the information describes the correspondence between a certain node and a port number. After the independent sub-networks reflecting the attribution information of the ports and the sub-networks are obtained through the steps, the obtained storage node information and the host port number aggregation information can be combined to correlate the nodes and the network, and the network topology information based on the nodes is generated.
In conclusion, the storage end can analyze the topology structure of the FC network where the storage is located, and generate the network topology information based on the nodes, so that the network topology information can be quickly and accurately obtained, and after the logic analysis is completed, the network topology information can be displayed in a graphical mode, so that a user can visually see the FC network topology structure where the storage is located, and the user experience is improved.
