Embodiment one
A kind of path loading method is present embodiments provided, is applied in first server, as shown in figure 1, the path carries
Enter method and specifically include following steps：
S101：First server is obtained in routing information according to the standby routing information from second server for receiving
Network interface identification information；
S102：First server according to network interface identification information, judge and second server between with standby routing information pair
Whether the standby path answered is legal path；
S103：First server is loaded into standby path after it is determined that standby path is legal path.
Wherein, first server can be the home server in InfiniBand networks, or InfiniBand
Far-end server in network.It is then corresponding, when first server is the home server in InfiniBand networks, second
Server is the far-end server in InfiniBand networks；Remote service in first server is InfiniBand networks
During device, second server is the home server in InfiniBand networks.Certainly, first server and second server also may be used
Think the far-end server and corresponding home server in other networks.
In embodiments of the present invention, the far-end server in first server as InfiniBand networks, remote service
QP on device is QP2, and second server is the home server in InfiniBand networks, and the QP on home server is QP1
As a example by the technical scheme in the embodiment of the present invention is explained.
When far-end server and home server are in communications status by main path, the state of QP1 and QP2 is
" Migrated " state, is under communications status, home server when far-end server and home server by main path
When preparing to be loaded into standby path, far-end server receives the standby routing information from home server, obtains in routing information
Network interface identification information；In the first embodiment, the network interface identification information that far-end server is obtained at least includes：Locally
The standby network interface SLID of the server and standby network interface DLID of far-end server.For example, home server and remote service
Device passes through main path（SLID=1, DLID=3）When under communications status, home server prepares to be loaded into standby path（SLID=2,
DLID=4）, then far-end server receives the standby routing information from home server includes SLID=2 and DLID=4.Second
Plant in implementation method, the network interface identification information that far-end server is obtained includes the GID (global of the standby network interface of far-end server
Identity, global identity mark) and the standby network interface of home server GID.
After the network interface identification information that far-end server is obtained in standby routing information, step S102 is performed, i.e.,：Distal end takes
Business device judges whether standby path corresponding with standby routing information between home server is legal according to network interface identification information
Path.
In specific implementation process, when continuing to use above-mentioned the first implementation method, step S102 is specifically included：Far-end server
According to the standby network interface number of far-end server and the standby network interface number of home server that standby routing information includes, remote service is judged
Whether the standby path between device and home server is legal path.
In specific implementation process, when continuing to use above-mentioned second implementation method, step S102 is specifically included：Far-end server
The global identity mark GID of the standby network interface of far-end server in standby routing information and the standby network interface of home server
GID, judges and whether the standby path between home server is legal path, such as, standby routing information is SLID=2 and DLID=
When 4, standby path is judged（SLID=2, DLID=4）Whether the path between two network interfaces is legal path.
Second implementation method is continued to use below to explain the technical method in the embodiment of the present invention.
Preferably, judge whether the standby path between far-end server and home server is legal path, specifically：Pass through
Judge whether the standby network interface SLID of far-end server is legal port numbers, at the same detect far-end server and home server it
Between link whether be in connection status.
Specifically, judge whether the standby network interface SLID of far-end server is that legal port numbers specifically may determine that distal end
The standby network interface SLID of server whether there is in far-end server and whether the standby network interface SLID of far-end server is in
" UP " state, such as, and the standby network interface SLID=4 of far-end server that the standby routing information that far-end server is received includes, then
Far-end server is detected and whether there is network interface number 4 on far-end server, and when far-end server has network interface number 4, then distal end takes
Business device continues to detect that whether network interface number 4, in " UP " state, when network interface number 4 is in " UP " state, then shows that SLID=4 is remote
Hold the legal port numbers of server.
Specifically, whether the link between detection far-end server and home server is specially in connection status：
Far-end server obtains the standby path of far-end server according to the standby routing information for receiving, and then far-end server judges standby path
Whether connection status is in determine the availability in standby path.It is determined that the availability in standby path is specifically included：Detection remote service
Whether the standby network interface of device damages, and whether the netting twine in standby path is pulled out etc., is by remote service in specific implementation process
Whether the state of network interface is in " down " shape on interface " ib_get_port_state " the detection network interface card contained on network interface card on device
State, when the state of network interface is in " down " state, then shows that network interface is damaged, or the netting twine in standby path is pulled out or damages.For example,
The standby routing information that far-end server is received includes SLID=2 and DLID=4, and far-end server is obtained according to the standby routing information for receiving
The standby path of the far-end server for arriving（SLID=4, DLID=2）.Then standby path is judged（SLID=4, DLID=2）Network interface 4 be
Whether the state of network interface 4 is in no damage, and interface " ib_get_port_state " detection network interface card on far-end server
" down " state.
Far-end server is performed after step S102, then performs step S103：Far-end server is it is determined that standby path is
Behind legal path, standby path is loaded into.
Specifically, standby routing information from home server of the far-end server in step S101 obtains distal end
The standby path of server, after being loaded into standby routing information, the state of QP2 from " Migrated " state transition be " Rearmed " state,
Such as, the standby routing information that far-end server is received includes SLID=2 and DLID=4, and far-end server is according to the standby path for receiving
The standby path of the far-end server that information is obtained is（SLID=4, DLID=2）, in standby path（SLID=4, DLID=2）It is legal road
During footpath, standby path is loaded into（SLID=4, DLID=2）.
Because far-end server is verified according to the standby routing information from home server to the legitimacy in standby path,
When the standby path of checking is legal path, far-end server is just loaded into standby path, thus it is guaranteed that far-end server loading is standby
The legitimacy in path.
Preferably, far-end server is after it is determined that standby path is legal path, far-end server sends one and shows standby road
Footpath is that legal path feeds back to home server.So that home server is receiving the feedback of far-end server transmission
After information, home server is just loaded into standby path.
Because far-end server determines standby path after legal path, to be loaded into standby path, will indicate that standby path is conjunction again
Method path feeds back to home server, thus it is guaranteed that the legitimacy in the standby path of the loading of home server side, and
Ensure that far-end server and home server are loaded into the uniformity in standby path.
Preferably, far-end server is when the standby network interface number of far-end server is judged for illegal port numbers, have and not only
There is the following two kinds implementation method.
The first implementation method performs following steps：
Step 1：One legal network interface number of far-end server of selection；
Step 2：Judge the suggestion path between the legal network interface number of far-end server of selection and home server network interface number
Link whether be in connection status；
Step 3：If the suggestion path between the legal network interface number of far-end server and home server network interface number of selection
Link be in connection status, it is determined that the legal network interface number of far-end server and the standby network interface number of home server of selection it
Between path be legal path, far-end server is loaded into the suggestion path, and the legal network interface number of the far-end server of selection is returned
Back to home server；
Step 4：If the suggestion path between the legal network interface number of far-end server and home server network interface number of selection
Link be not on connection status, then determine whether non-selected legal network interface number：If non-selected legal network interface
Number then return to step 1, does not have non-selected legal network interface number then to determine that suggestion path is illegal path.
For example, far-end server includes network interface number 2（Main path network interface number）, network interface number 5, far-end server is in step S101
The standby routing information from home server of middle acquisition includes SLID=2 and DLID=4, then judge distal end according to standby routing information
The standby network interface card slogan 4 of server is illegal port numbers, and far-end server selects legal network interface number 5, and judges legal network interface number 5
Whether connection status is in the suggestion path between the standby network interface number 2 of home server, if it is, far-end server is loaded into building
View path（SLID=5, DLID=2）.
In specific implementation process, the legal port numbers of far-end server that far-end server returns to home server are logical
Main path transmission is crossed, specifically, home server can be sent to by way of routing information, or individually send
The form of the legal network interface number of remote service, does not enter to the form for sending the legal port numbers of far-end server in embodiments of the present invention
Row limitation.
Because far-end server is when standby path is illegal path, far-end server knows other network interfaces number of local terminal,
Therefore, one far-end server end of far-end server selection is present and the network interface number in upstate is used as legal network interface number,
Improve standby path（It may be suggestion path）It is the possibility in legal path, therefore further ensures guarantee InfiniBand
The reliability of network communication link.
Second implementation method：One legal network interface number of far-end server of selection sends in the form of advising path or individually
The form of legal network interface number returns to home server, therefore, in step S101 far-end server receive from local service
The standby routing information of device can be the standby routing information that home server sends first, or be based in far-end server
After the standby routing information authentication failed that home server sends first（The corresponding standby path of standby routing information for sending first is not for
Legal path）Return to the suggestion routing information of home server.
It is above-mentioned for network interface identification information be server network interface number as a example by the technical scheme in the embodiment of the present invention is carried out
Describe in detail, according to the corresponding relation of server network interface number and the GID of server network interface, those skilled in the art will be seen that
It is succinct for specification for the detailed embodiment that network interface identification information is loaded into for the path of the GID of server network interface,
This is repeated no more.
Further, in specific implementation process, first server is home server, and second server is far-end server
When, those skilled in the art can be loaded into according to the implementation principle realizing route described in embodiment one, for the letter of specification
It is clean, will not be repeated here.
