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 obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a configuration method of an IP address of a storage device according to an embodiment of the present invention is described in detail. Fig. 1 is a signaling diagram of a method for configuring an IP address of a storage device according to an embodiment of the present invention, where the method includes:
s101: after the storage equipment is powered on and started, whether the storage equipment is configured with the IP address or not is detected.
After the storage equipment is powered on and started, whether the IP address is configured or not can be automatically detected. And when the IP address is configured, executing normal operation. When the storage device itself does not configure the IP address, the storage device needs to acquire the IP address at this time, i.e., S102 is performed.
S102: when the self is not configured with the IP address, the storage device broadcasts an IP allocation request carrying the self device identification outwards.
In the embodiment of the invention, in order to avoid the situation that different storage devices share the same IP address, the storage devices carry the device identifiers when broadcasting the IP allocation request outwards.
S103: and when the management center acquires the IP allocation request, traversing all IP addresses in the preset IP network segment, and screening out available IP addresses.
In the embodiment of the present invention, in order to improve the efficiency of the management center in allocating IP addresses to the storage device, an IP network segment may be set in advance in the management center, and the IP network segment includes a plurality of IP addresses.
In practical application, one IP address can only be used by one device, and in order to ensure the availability of the IP address allocated to the storage device, the management center can traverse all the IP addresses in the preset IP network segment, and detect the availability of each IP address, thereby screening out the available IP addresses.
In a specific implementation, whether the IP address is available or not may be detected in a ping communication manner. The management center can sequentially execute ping operation on all IP addresses in the preset IP network segment; when the IP address is already occupied by other devices, the management center can realize ping communication with the IP address, so that the management center can mark the IP address of ping communication as an unavailable IP address. When the IP address is not occupied by other devices, the management center cannot ping the IP address, so that the management center can mark the IP address which is not ping as an available IP address.
S104: the management center selects a target IP address corresponding to the equipment identifier from all available IP addresses depending on the equipment identifier carried in the IP allocation request.
It is considered that there are often a plurality of available IP addresses, and there may be a plurality of IP allocation requests received by the management center at the same time. In practical application, the management center can select a corresponding number of target IP addresses from the available IP addresses according to the number of the IP allocation requests; and a one-to-one correspondence relationship between each device identifier and the target IP address is established, namely, a corresponding target IP address is allocated to each device identifier, so that the condition that the IP addresses allocated to each storage device are not repeated is ensured.
S105: the management center broadcasts the target IP address and the equipment identification as configuration information.
The management center may use each destination IP address and its corresponding device identification as a piece of configuration information. Considering that there may be multiple storage devices that need to acquire IP addresses at the same time, the management center may obtain multiple pieces of configuration information.
In practical application, the management center may sequentially broadcast each piece of configuration information outwards, or may package all pieces of configuration information into one data packet to be broadcast outwards.
S106: and when the storage equipment acquires the configuration information broadcasted by the management center, judging whether the equipment identifier carried in the configuration information is matched with the equipment identifier of the storage equipment.
When the management center broadcasts each piece of configuration information outwards in sequence, the storage device can judge whether the device identifier carried in the piece of configuration information is matched with the device identifier of the storage device after acquiring each piece of configuration information. When there is a match between the device identifier carried in a certain piece of configuration information and the device identifier of the user, S107 is executed.
When the management center packs all the configuration information into a data packet for broadcasting, the storage device may sequentially determine the configuration information carried in the data packet after acquiring the data packet, and when there is configuration information matching with the device identifier of the storage device, execute S107.
S107: and when the equipment identifier carried in the configuration information is matched with the own equipment identifier, the storage equipment takes the target IP address carried in the configuration information as the own IP address.
In consideration of the fact that in practical application, in the period from the time when the management center broadcasts the configuration information to the time when the storage device acquires the configuration information, the target IP address carried in the configuration information may be occupied by other devices, so that, in order to further ensure the availability of the target IP address acquired by the storage device, the storage device may first determine whether the target IP address carried in the configuration information is ping-on before the target IP address carried in the configuration information is used as its own IP address; when the target IP address cannot ping, it indicates that the target IP address is not occupied, and at this time, the storage device may use the target IP address as its own IP address.
In practical application, the storage device may call an underlying CLI interface to configure the target IP address as its own IP address.
According to the technical scheme, after the storage equipment is powered on and started, whether the storage equipment is configured with the IP address or not is detected; and when the self is not configured with the IP address, the IP allocation request carrying the self equipment identification is broadcasted outwards. And when the management center acquires the IP allocation request, traversing all IP addresses in the preset IP network segment, and screening out available IP addresses. By screening the IP addresses in the IP network segment, the availability of the screened IP addresses can be ensured. In order to avoid the situation that different storage devices share the same IP address, the management center can select a target IP address corresponding to the equipment identifier from all available IP addresses depending on the equipment identifier carried in the IP allocation request; and broadcasting the target IP address and the equipment identification as configuration information. When the storage equipment acquires the configuration information broadcasted by the management center, judging whether the equipment identification carried in the configuration information is matched with the equipment identification of the storage equipment; when the device identifier carried in the configuration information matches the device identifier of the storage device, it indicates that the target IP address carried in the configuration information is the unique IP address allocated to the storage device by the management center, so that the storage device can use the target IP address carried in the configuration information as the IP address of the storage device. In the technical scheme, the IP address configuration process is initiated by the storage device, the management center allocates the IP addresses for the storage device depending on the device identifier, the situation that the same IP address is occupied by a plurality of storage devices is avoided, and the management center can realize automatic configuration of the IP addresses of the plurality of storage devices. The efficiency of IP address configuration is improved on the premise of ensuring the availability of the IP address.
In order to avoid that the management center reallocates the target IP address allocated to the storage device to other devices, the management center can record the corresponding relationship between the target IP address and the device identifier after selecting the target IP address corresponding to the device identifier from all available IP addresses, so that the management center can clearly know which IP addresses in the preset IP network segment have been allocated to the storage device.
In practical application, the management center may record the corresponding relationship between the target IP address and the device identifier in the LLDP message body manner. After the management center allocates a corresponding target IP address to the new device identifier each time, a TLV field may be added to the LLDP message body, and the target IP address, the device identifier corresponding to the target IP address, and the message type are written into the TLV field.
In consideration of that the LLDP message body of the management center records other types of information besides the corresponding relationship between the target IP address and the device identifier, in order to facilitate the management center to intuitively know the function of the stored information, the TLV field may store the corresponding message type, for example, the message type is an IP allocation request, in addition to the target IP address and the device identifier corresponding thereto.
By adopting the LLDP message body to record the target IP address and the corresponding device identification thereof, the management center can clearly know which IP addresses in the preset IP network segment are occupied by the storage device, thereby effectively avoiding the situation that the target IP address allocated to the storage device is reallocated to other devices, and ensuring the reasonable calling of the management center to the IP address in the preset IP network segment.
