Table 6‑2. Columns of the DR IP Customizer CSV File (Continued)
Column Description Customization Rules
DNS Server(s) Address of the DNS server or servers. Customizable. Can be left blank.
If you enter this setting in an Adapter
ID 0 row, it is treated as a global
setting. On Windows virtual machines,
this setting applies for each adapter if
you set it in the Adapter ID rows other
than Adapter ID 0.
On Linux virtual machines, this is
always a global setting for all adapters.
This column can contain one or more
IPv4 or IPv6 DNS servers for each
NIC.
DNS Suffix(es) Suffix or suffixes for DNS servers. Customizable. Can be left blank.
These are global settings for all
adapters on both Windows and Linux
virtual machines.
Modifying the DR IP Customizer CSV File
You modify the DR IP Customizer comma-separated value (CSV) file to apply customized networking
settings to virtual machines when they start on the recovery site.
NOTE This release of Site Recovery Manager allows you to define subnet-level IP mapping rules to
customize IP settings on virtual machines, as well as by using the DR IP Customizer tool. You can use
subnet-level IP mapping rules in combination with DR IP Customizer. For information about how you can
use subnet-level IP mapping rules and DR IP Customizer together, see “Customizing IP Properties for
Multiple Virtual Machines,” on page 67.
One challenge of representing virtual machine network configurations in a CSV file is that virtual machine
configurations include hierarchical information. For example, a single virtual machine might contain
multiple adapters, and each adapter might have multiple listings for elements such as gateways. The CSV
format does not provide a system for hierarchical representations. As a result, each row in the CSV file that
the DR IP Customizer generates might provide some or all of the information for a specific virtual machine.
For a virtual machine with a simple network configuration, all the information can be included in a single
row. In the case of a more complicated virtual machine, multiple rows might be required. Virtual machines
with multiple network cards or multiple gateways require multiple rows. Each row in the CSV file includes
identification information that describes to which virtual machine and adapter the information applies.
Information is aggregated to be applied to the appropriate virtual machine.
Follow these guidelines when you modify the DR IP Customizer CSV file.
n
Omit values if a setting is not required.
n
Use the minimum number of rows possible for each adapter.
n
Do not use commas in any field.
n
Specify Adapter ID settings as needed. DR IP Customizer applies settings that you specify on Adapter
ID 0 to all NICs. To apply settings to individual NICs, specify the values in the Adapter ID 1, 2, ..., n
fields.
n
To specify more than one value for a column, create an additional row for that adapter and include the
value in the column in that row. To ensure that the additional row is associated with the intended
virtual machine, copy the VM ID, VM Name, vCenter Server, and Adapter ID column values.
