Embodiment 1
[0022] figure 2 It is a schematic flowchart of a hot backup method according to an embodiment of the present invention. Such as figure 2 As shown, the hot backup method includes:
[0023] Step S201, the slave management board in the standby state receives the domain identifier of the hot backup device and exchange link parameter negotiation information sent by the main management board in the working state, wherein the hot backup device includes the slave management board in the standby state and the The main management board of the working status;
[0024] Step S202, the slave management board in the standby state receives a master-slave switch trigger message, and switches to the working state in response to the master-slave switch trigger message;
[0025] Step S203, the slave management board switching to the working state initiates a non-interrupted fiber channel network architecture reconfiguration process, so as to obtain the network state synchronization informati...
Embodiment 2
[0038] On the basis of the first embodiment above, if the hot backup device is the main switch in the fiber channel network architecture, it also includes:
[0039] The domain identifier of the ordinary switch in the fiber channel network architecture sent by the master management board receiving the working state from the management board in the standby state;
[0040] Correspondingly, the keeping the domain identifier of the hot backup device unchanged in the reconfigured Fiber Channel network architecture specifically includes:
[0041] In the reconfigured Fiber Channel network architecture, keep the domain identifiers of the master switch and the common switch unchanged.
[0042] below in figure 1 Executing the hot backup method of this embodiment on the main switch (for example, switch A) will be described.
[0043] Specifically, when switch A is working on the master management board, in addition to synchronizing the switching link parameter negotiation information and...
Embodiment 3
[0047] The hot backup device in this embodiment is, for example, an FC switch. image 3 It is a schematic structural diagram of a hot backup device according to an embodiment of the present invention. Such as image 3 As shown, the hot backup device includes a first management board 31 and a second management board 32, wherein the first management board 31 and / or the second management board 32 (only the second management board 32 is shown as an example in the figure specific structure) including:
[0048] The synchronous receiving module 321 is used to receive the domain identification of the hot backup device and exchange link parameter negotiation information sent by another management board in the working state in the standby state;
[0049] The master-slave switching module 322 is configured to receive a master-slave switch trigger message, and switch to a working state in response to the master-slave switch trigger message;
[0050] The reconfiguration module 323 is co...

Abstract
The invention provides a hot backup method and a piece of hot backup equipment. The method comprises the following steps: receiving the domain identifier of the hot backup equipment and the parameter consultation information of exchange links which are all transmitted from a principal management plate in a working state by a subordinate management plate in a spare state, wherein the hot backup equipment comprises the subordinate management plate in the spare state and the principal management plate in the working state; receiving the principal and subordinate switching trigger messages by the subordinate management plate in the spare state, and responding and switching the principal and subordinate switching trigger messages into the working states; initiating the structure re-configuration process of a non-interrupt fiber channel network by the subordinate management plate in the working state, obtaining the synchronous information of the network states of the hot backup equipment through the structure re-configuration process of the non-interrupt fiber channel network, and keeping the domain identifier of the hot backup equipment unchanged in the re-configured structure of the fiber channel network; and executing the work by the subordinate management plate in the working state according to the parameter consultation information of the exchange links and the synchronous information of the network states.
Description
technical field [0001] The invention relates to a hot backup technology, in particular to a hot backup method and equipment, and belongs to the technical field of communication. Background technique [0002] With the rapid development of the Internet (Internet), the network has become an indispensable part of social life. The communication and exchange of enterprises and individuals cannot be separated from the use of the network, so the requirements for the reliability of the network are becoming more and more high. Hot backup technology is a high fault-tolerant application method combining software and hardware. It can replace the faulty module with a spare module without interrupting the operation. After the fault is eliminated, the system can automatically re-synchronize the operation, thereby effectively improving Equipment reliability, to avoid interruption of operation due to equipment failure. [0003] Currently, a master management board and a slave management boa...
