Detailed Description

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 entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for setting a storage device network. Fig. 1 is a schematic diagram illustrating an embodiment of a setting method for a storage device network according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:

s01, in response to the fact that the storage device in the cluster is detected to start to operate, judging whether the storage device is a configuration node of the cluster;

s02, if the storage device is a configuration node of the cluster, respectively setting a cluster IP and a service IP on a first port of the storage device; and

s03, sequentially carrying out device service IP on other ports of the storage device;

wherein, the cluster IP and the service IP are distinguished by the network name and the label.

In the present embodiment, in the network technology, a network Port (Port) has two meanings: one is a physical port, such as an ADSL Modem, a hub, a switch, and an interface of a router for connecting other network devices, such as RJ-45 ports, SC ports, and the like; the second is a port in a logical sense, which generally refers to a port in a TCP/IP protocol, and the port number ranges from 0 to 65535, such as 80 ports for browsing a web service, 21 ports for an FTP service, and the like. The network port referred to in this method refers to the former, physically referred ethernet (ethernet) port. Ethernet is currently the most widely used lan communication method and also a protocol. The ethernet protocol defines a series of software and hardware standards to connect different computer devices together. The basic elements of ethernet device networking are switches, routers, hubs, optical fibers, and ordinary network cables, as well as ethernet protocols and communication rules. The port of the network data connection in the ethernet is the ethernet interface. In a local area network, two IP addresses are unique, one is a network number and one is a broadcast address. The network number is an address for three-tier addressing, which represents the entire network itself; the other is a broadcast address, which represents the entire host of the network. The network number is the first address in the network segment, the broadcast address is the last address in the network segment, and the two addresses cannot be configured on the host computer. For example, in the network segments 192.168.0.0 and 255.255.255.0, the network number is 192.168.0.0 and the broadcast address is 192.168.0.255. Thus, in a local area network, two less addresses (network number, broadcast address) can be allocated in the computer than in the network segment, these addresses being referred to as host addresses. In the above example, only 192.168.0.1 to 192.168.0.254 of the host address can be configured on the computer.

In this embodiment, for a multi-control cluster, the management network and the service network need to be separated. After managing the network settings, the corresponding routing rules and routing table information of the managed network need to be set. The routing table and the routing table rule are independently set according to each port, so that network faults caused by routing conflicts are avoided.

In this embodiment, when the storage device runs, the corresponding management network address needs to be set, where the management network address includes a cluster IP, a service IP, and a service IP. The cluster IP and the service IP are set on the first port of the device, and are distinguished by the network name + label. The service IP is in turn set on the following port. For a dual-control cluster, cluster IP is configured only on the configuration nodes. Service IP is configured on each controller.

Matching a routing rule with a routing table name eth0 in an ip rule, and clearing the corresponding ip rule; according to the cluster IP setting, matching an IP route with a routing table name eth0 in the IP route, and clearing the corresponding IP route; a routing table named eth0 is created, the route corresponding to the cluster ip is created, and the command on the default route eth0 is set as follows:

Ip route add gateway dev eth0 proto kernel scope link src ip_addr

Ip route add default via gateway dev eth0

And creating a routing table named sat, and creating a route corresponding to the service IP. And the commands on the default route eth0 are set as follows:

Ip route add gateway dev eth0 proto kernel scope link src ip_addr

Ip route add default via gateway dev eth0 proto kernel scope link src ip_addr

In this embodiment, if the service IP is configured continuously, and when the service IP is set, an IP route in eth1, for example, with a routing table name as a corresponding port is matched in the IP route, and the corresponding IP route is cleared. According to the service IP setting, matching an IP route with a routing table name eth1 in the IP route, and clearing the corresponding IP route. A routing table named eth1 is created, and a route corresponding to the service IP is created, with the following commands:

Ip route add gateway dev eth1 proto kernel scope link src ip_addr

and creating a routing rule with prio of 200, wherein the routing rule is correspondingly a cluster ip _ addr and matches the routing of table eth 1.
