If the firewall inbound rules of the replica server do not allow port 80 access, the following error occurs:

650) This. width = 650; "Title =" clip_image010 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image010 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968914MArY.png "width =" 393 "Height =" 314 "/>

Solution: Create an inbound rule on the copy server hv02 to allow connection to port 80.

2) VM replication process

After the replication starts, you can view the replication status of the virtual machine through the hyper-V manager.

650) This. width = 650; "Title =" clip_image011 "style =" border-top: 0px; border-Right: 0px; border-bottom: 0px; border-left: 0px; display: inline "border =" 0 "alt =" clip_image011 "src =" http://img1.51cto.com/attachment/201407/10/8946015_14049698634tHe.png "" 574 "Height =" 484 "/>

The detailed information of the copy operation status is:

650) This. width = 650; "Title =" clip_image012 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image012 "src =" http://img1.51cto.com/attachment/201407/10/8946015_14049689168Vw0.png "width =" 664 "Height =" 445 "/>

The hyper-V replica folder is automatically generated in the target folder on the replica server and contains the following three folders:

The details of virtual hard disks and virtual machines are as follows:

650) This. width = 650; "Title =" clip_image015 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image015 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968918nrt2.png "width =" 828 "Height =" 108 "/>

After replication synchronization is complete, you can find that the master server and the replica server have exactly the same time, while the replica server also has a WIN7-01 of this virtual machine.

650) This. width = 650; "Title =" clip_image017 "style =" border-top: 0px; border-Right: 0px; border-bottom: 0px; border-left: 0px; display: inline "border =" 0 "alt =" clip_image017 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404969867jISY.png "" 636 "Height =" 484 "/>

3) test failover

On the hv02 host machine select Win7-01 --> copy --> test failover

Click "test failover,

650) This. width = 650; "Title =" clip_image019 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image019 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968922CEYl.png "width =" 459 "Height =" 196 "/>

A Win7-01 Test Virtual Machine is generated in hyper-V manager with detailed hard disk file information

650) This. width = 650; "Title =" clip_image020 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image020 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968922JzAa.png "width =" 855 "Height =" 140 "/>

4) Enable failover

Select Win7-01 --> copy --> planned failover on hv01

650) This. width = 650; "Title =" clip_image021 "style =" border-top: 0px; border-Right: 0px; border-bottom: 0px; border-left: 0px; display: inline "border =" 0 "alt =" clip_image021 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404969869JAJy.png "" 244 "Height =" 208 "/>

650) This. width = 650; "Title =" clip_image022 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image022 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968924COYd.png "width =" 562 "Height =" 321 "/>

Click "failover" to perform some basic checks. If no relevant settings have been made before, the following error window will pop up:

650) This. width = 650; "Title =" clip_image023 "style =" border-left-0px; border-right-width: 0px; border-bottom-width: 0px; border-top-width: 0px "border =" 0 "alt =" clip_image023 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404968924HPLg.png "width =" 365 "Height =" 221 "/>

The solution to the above error is: Set the hv01Copy ConfigurationAs follows:

650) This. width = 650; "Title =" clip_image024 "style =" border-top: 0px; border-Right: 0px; border-bottom: 0px; border-left: 0px; display: inline "border =" 0 "alt =" clip_image024 "src =" http://img1.51cto.com/attachment/201407/10/8946015_1404969872jCGd.png "" 515 "Height =" 484 "/>
