h. Specify your Storage Mirroring bandwidth limiting parameters.

 No Bandwidth Limit—Data will be transmitted using all available bandwidth.

 Fixed Bandwidth Limit—Data will be transmitted according to the user-specified bandwidth configuration. By

default, the Unlimited checkbox is enabled. This configuration is identical to selecting No Bandwidth Limit. If

you want to limit your bandwidth usage, clear this checkbox. To limit the bandwidth usage, enter the maximum

amount of data you want to transfer per second. You can indicate it by specifying your

Connection Speed and

the Percentage of the bandwidth that you want to use or by entering the Transfer Rate value directly.

i. Click Next to continue.

j. Specify your Storage Mirroring orphan file parameters. By default, the orphan files feature is disabled. To enable it,

select

Move/Delete Orphan Files. Specify if you want to delete or move the files. If you select the move option,

identify the location where these orphan files will be located. Click

Next to continue.

k. Specify your Storage Mirroring compression parameters. By default, compression is disabled. To enable it, select

Enable Compression. Depending on the compression algorithms available for your operating system, you may see a

slider bar indicating different compression levels. Set the level from minimum to maximum compression to suit your

needs.

l. Click Finish to complete the creation of the Storage Mirroring Source Connection resource.

8. Bring the Storage Mirroring Source Connection resource and the virtual server resources online.

Understanding the Source Connection Resource

When the Storage Mirroring Source Connection resource is brought online (or taken offline) a command shell environment

is created and a Storage Mirroring DTCL script is executed. The script either establishes a Storage Mirroring connection or

disconnects the Storage Mirroring connection, depending on the node. If you are using the Storage Mirroring Source

Connection resource, the cluster object will control these scripts as the cluster service switches between nodes. If you do

not use the Storage Mirroring Source Connection resource, there is no mechanism to bring a Storage Mirroring connection

online. The non-owning node does not know that a connection was present because the connection information is not

replicated between systems. Therefore, if that non-owning node becomes the owner, the connection would need to be

manually re-established. So it is important to always use the Storage Mirroring Source Connection resource when the source

is a cluster configuration.

You can modify the features of the Storage Mirroring Source Connection resource by right-clicking the resource and selecting

Properties. The same features will be available on the tabs as was presented when the resource was created.

Outlined briefly below are the steps used in the Storage Mirroring DTCL scripts. The processing results of the scripts can be

found in the file

dtsc.log in the same directory where Storage Mirroring is installed.

Online script used to establish a connection

1. Identify the elements used in the script: source, target, replication set, and so on.

2. Login to the target.
