The invention provides the centralized control changing method of a kind of data center, described method is used for the master of at least one pair of server at two data centers (master data center and preliminary data the center)-relation of being equipped with is exchanged, described two data centers respectively comprise an intelligence memory and multiple servers, lay respectively at and have relation one to one between the server at described two data centers, and the consistency group STgroup and the corresponding logical storage area of every pair of server in the intelligence memory that lays respectively at two data centers, have been defined, every station server has a service IP address and a unique management ip address, and every pair of server timesharing uses same production IP address as the service IP address.
The server at master data center for example is the n station server of HOST (H1) to HOST (Hn), and the external Storage S that is stored as at master data center has defined each server logical memory block, master data center among the Storage S; The server at preliminary data center then is HOST (H1 ') to the n station server of HOST (Hn '), and the external Storage S ' that is stored as at preliminary data center has defined each server logical memory block, preliminary data center among the Storage S '.According to techniques well known as can be known; so-called STgroup group is LUN (the Logical Unit Number of intelligence memory disk; LUN) notion of aspect; to be distributed on the LUN on Storage S and the Storage S '; definition becomes a consistency group; if one of them LUN can't carry out write operation, the write operation of other LUN also will be failed in then organizing hereto, thereby realize the consistency protection for the data of a storage LUN group.Two intelligent storages in the embodiment of the invention can be by intensive multiplexed optical wave (Dense Wavelength DivisionMultiplexing, DWDM) network connects and realizes the disk synchronization replication, the server of each data center can pass through the storage area network network, and (Storage Area Network, SAN) intelligence memory with the notebook data center is connected.As shown in Figure 1, the centralized control changing method of described data center comprises:
Step S101: receive switching command, specify at least one pair of to lay respectively at the server at described two data centers in the described switching command;
Step S102:, treating to carry out the inactive script of server on the inactive server by management ip address;
Step S103: on described at least one pair of server, carry out IP according to described switching command and revise script, the production IP address of described at least one pair of server is switched to waiting that enabling server uses by the server of waiting to stop using;
Step S104: the master-inferior relation of the consistency group of described at least one pair of server in intelligence memory is exchanged;
Step S105:, waiting to enable the script of carrying out the startup of server application on the server by management ip address.
Below be that HOST (H1) is switched to HOST (H1 ') is that example describes with the switching command of in step S101, receiving.Each server of data center has two IP addresses: one is the service IP address that is used to provide service, and another is the management ip address that is used to accept to manage control.The inactive script of server is pre-stored in each server.
Among the step S102, treat that inactive server HOST (H1) receives the instruction of carrying out the inactive script of server, then HOST (H1) can carry out the inactive script of server, stops its application service.
After step S102 stops to treat the service of inactive server HOST (H1), comprise that also the control hardware supervisor console calls the hardware resource management script, treat the server HOST that enables (H1 ') and carry out the adjustment (comprising start-stop, resource adjustment etc.) of hardware view (as integrated circuit board, CPU, internal memory), for example the control hardware supervisor console calls the hardware resource management script work CPU of HOST (H1 ') is adjusted into 4 by 1.

It is 136 management ip address that # judges whether to exist back three
netstat-in|grep-v?lo0|grep-v″link#″|awk′{print?$1，″″，$4}′|grep″136.″＞/dev/null
if[$？＝0]
then
If the # management ip address exists, extract management IP address then, with behind the management ip address 3 change 173 back assignment into and give network interface card, be that the service IP address of network interface card be the IP address of awaiting orders by producing the IP address switchover, and point out and finish switching
MANAGE_IP＝`netstat-in|grep-v?lo0|grep-v″link#″|awk′{print$1，″″，$4}′|grep″136.″|awk′{print?$2}′`
EXCHANGE_IP＝`echo?$MANAGE_IP|sed′s/^136/173/g′`
chdev-l?$SRV_ENT-a?netaddr＝$EXCHANGE_IP＞/dev/null
if[$？＝0]
then
echo″0080-Change?$SRV_ENT?IP?successfully.″
# judges that IP switches whether success, and with message notifying, if failure then withdraw from
CURRENT_IP＝`netstat-in|grep-v?lo0|grep-v″link#″|grep″^$SRV_ENT″|sed-n′1p′|awk′{print?$4}′`
echo″The?current?IP?is${CURRENT_IP}.″
