| 00-0D-88-F8-33-47 | b | T2 | 1.1.1.1 |
| 00-0D-88-F8-33-48 | c | T3 | 1.1.1.1 |
In an embodiment of the present invention, main frame need be configured to DHCP when adding network and obtain the IP address automatically, then by obtaining the IP address alternately with Dynamic Host Configuration Protocol server, this moment, Dynamic Host Configuration Protocol server was noted the MAC Address of main frame, be divided into two kinds of situations again: when main frame when direct-connected with Dynamic Host Configuration Protocol server (promptly not being connected) by route equipment, host computer system directly sends to Dynamic Host Configuration Protocol server with the DHCP request message, and the source MAC of this message is host MAC address; When main frame and Dynamic Host Configuration Protocol server when not direct-connected (promptly being connected) by routing device, DHCP request message message by routing device after its source MAC can become the MAC Address of router interface, this interface is exactly the interface that links to each other with Dynamic Host Configuration Protocol server.In this case, Dynamic Host Configuration Protocol server can not be determined the MAC Address of main frame according to the source MAC of the DHCP message that is obtained, the way that addresses this problem is to open DHCP Relay function on routing device, and support DHCP option Option82, like this when router when Dynamic Host Configuration Protocol server is transmitted the DHCP request message, host MAC address can be filled in the option Option82 field, thereby allow Dynamic Host Configuration Protocol server obtain host MAC address information.
Main frame uses client software (for example DiskSafe) to create storage resources usually on storage server, at this moment, main frame is set up iSCSI with storage server and is connected, storage server record host MAC address (storage server obtains host MAC address from Dynamic Host Configuration Protocol server) and corresponding iSCSI link information, and send it to Dynamic Host Configuration Protocol server.
When main frame need carry out the data recovery, use usually and recover CD (for example RecoveryCD) startup, after the system start-up, to Dynamic Host Configuration Protocol server transmission DHCP request, the request Dynamic Host Configuration Protocol server is its distributing IP address.
When Dynamic Host Configuration Protocol server receives from the DHCP of main frame request, in related information, search the MAC Address whether this main frame is arranged, also be divided into two kinds of situations here:
In related information not during the MAC Address of this main frame, it then is this host assignment IP address, and the MAC Address of record main frame, corresponding to when carrying out data backup, set up the step (referring to the processing in the step 201) of the related information of host MAC address and iSCSI link information;
When the MAC Address of this main frame is arranged,, also send private message in related information, corresponding " Initiator title, Target title, Target address " sent to main frame to main frame then except being this host assignment IP address.
For example, Dynamic Host Configuration Protocol server receives DHCP when request that MAC Address is the 00-0D-88-F8-33-46 main frame, searches the MAC Address whether this main frame is arranged in related information, if there is not this MAC Address, then notes and the distributing IP address; If this MAC arranged, then Inistiator title " a ", Target title " T1 " and Target address " 1.1.1.1 " are sent to main frame by proprietary protocol.
After the main frame that use to recover optical disk start-up receives the private message that comprises " Initiator title, Target title, Target address " from Dynamic Host Configuration Protocol server, set up iSCSI according to information wherein with storage server and be connected.For example, MAC Address is that the main frame of 00-0D-88-F8-33-46 receives and comprises information: the private message of Inistiator title " a ", Target title " T1 " and Target address " 1.1.1.1 " relies on these information to set up iSCSI and connects.Afterwards, passing through the iSCSI that set up connects and from storage server data is returned to local host.
In the present invention, Dynamic Host Configuration Protocol server also can be built in the storage server, also is that storage server provides the DHCP function simultaneously, and its data recovery procedure does not have essential distinction with the data recovery procedure among the above-mentioned embodiment.
Corresponding to the description of above data reconstruction method, below introduce the described data recovery system of the embodiment of the invention.Please refer to Fig. 3, the described data recovery system of the embodiment of the invention comprises main frame, Dynamic Host Configuration Protocol server and storage server.
