Pre-Failover Script

and

Post-Failover Script

—If you want to execute a script on the target before failover

(

Pre-Failover Script

) begins or after failover has occurred (

Post-Failover Script

), specify the path to the script on

the target. You can also search for the script by clicking

Browse

. The script will be processed using the same user

account that is configured to run the Storage Mirroring service. Scripts may contain any valid Windows command,
executable, batch, or script file. The

Pre-Failover Script

will be executed as soon as the failover process is initiated.

The

Post-Failover Script

will be executed after the failover process ends and the target has been rebooted.

‹

Network Mapping

—Specify how you want to handle network configurations on the target after failover.

‹

Apply source network configuration to the target

—If you select this option, the source IP addresses will be failed

over to the target. The IP addresses associated with each NIC on the source will be mapped to the NIC you specify
on the target. If the source has more NICs than the target, some of the source NICs will not be mapped to the target,
or the target NICs may need to be used for more than one source NIC. If there are more NICs on the target than
the source, the additional NICs will still be available after failover. If you are using a LAN environment, you should
select this option.

‹

Retain target network configuration

—If you select this option, the source IP addresses will not be failed over to

the target. The target will retain all of its original IP addresses. If you are using a WAN environment, you should select
this option. The following options are available if you want to update DNS.

‹

DNS Server

—The source’s primary DNS server is selected by default. If desired, you can select a different

DNS server.

‹

Source Server IP

—Select the IP address from the source that you want to remap to an IP address on the

target.

‹

Target Server IP

—Select an IP adddress on the target that will be replace the source IP address in DNS.

‹

Username

—Specify a user that has privileges to access and modify DNS records. The account must be a DNS

Admin for the domain in which the DNS server resides. You can enter a user name for a different domain by
entering a fully qualified user name. The fully qualified user name must be in the format domain\username or
username@domain. If you enter a non-qualified name, the DNS domain will be used by default. The domain
name is obtained from the DNS server name, provided that reverse lookup in DNS is enabled.

‹

Password

—Enter the password that is associated with the specified user name.

After you have entered the DNS information, click

Test

to validate that DNS is configured correctly and that the

specified credentials are sufficient to update DNS. When the DNS configuration is complete, click

OK

to save your

entries and return to the Configure Protection window.

‹

Route

—By default, Full-Server Failover will select the default route for transmissions. If desired, select a different IP

address on the target that will be used for Full-Server Failover transmissions.

‹

Mirroring

—Select the type of Storage Mirroring mirroring process you want to perform. A

Full

mirror will transmit all

files from the source to the target. A

Checksum

mirror will transmit only the blocks of data that are different between

the source and target.

‹

Compression

—Select the level of compression that you want to use. This reduces the amount of bandwidth needed to

transmit data from the source to the target. The data is compressed before being transmitted and then is uncompressed
before it is written on the target. If desired, you can also disable

Compression

.

After you have configured the settings on the various tabs, click

OK

to return to the main Full-Server Failover Manager

window.
