In order for Storage Mirroring Recover to find the pre-existing disk, the virtual
disk file names must be formatted using the convention SourceServer_
DriveLetter. For example, if your source server is Alpha and you are
protecting drives C and D, Storage Mirroring Recover will look for the file
names Alpha_C.vmdk and Alpha_D.vmdk. If you are using IP addresses,
substitute the IP address for the server name. For example, if the IP address
for server Alpha is 172.31.10.25 then Storage Mirroring Recover will look for
the file names 172.31.10.25_C.vmdk and 172.31.10.25_D.vmdk.
If you originally created a virtual disk and specified the source server by its IP
address, the pre-existing virtual disk file name cannot use the server name.
However, you can rename that file and its associated -flat.vmdk file to use the
IP address. The reverse is also true. If you originally specified the source
server by its name, the pre-existing virtual disk file name cannot use the
server’s IP address. However, you can rename the file and its associated -
flat.vmdk to use the source name. For example, if you originally created a
virtual disk and specified the source by its IP address, you need to rename
the file source_name_drive.vmdk to source_IPaddress_drive.vmdk. You also
need to rename the file source_name_drive-flat.vmdk to source_IPaddress_
drive-flat.vmdk. The reverse (change source_IPaddress to source_name for
both files) is also true. Additionally, you will need to edit the .vmdk file
manually because it contains the name of the -flat.vmdk file. Modify the
reference to the -flat.vmdk file to the new name you have specified using any
standard text editor.
In a WAN environment, you may want to take advantage of the Use pre-
existing virtual disks feature by using a process similar to the following.
a. Create a protection job in a LAN environment, letting Storage Mirroring
Recover create the virtual disk for you.
b. Complete the mirror process locally.
c. Disconnect the protection job.
d. Shut down and move the ESX target server to your remote site.
e. After the target server is back online at the remote site, create a new
protection job for the same source server and select to Use pre-
existing virtual disks. Storage Mirroring Recover will reuse the
existing .vhd files and perform a difference mirror over the WAN to bring
the virtual machine up-to-date.
15. Click Next to continue.
16. Configure the replica virtual machine that will be created on the target.
