Drive Mapping Information

When you connect a source disk to another computer, named the host computer, CA DMM displays all the operating systems and their drive maps (in the source disk) in the Disk-To-Disk Drive Mapping page. The host computer also displays the drive where the operating system is installed in the Source OS drop-down list. If the source disk is a multiboot disk, the Source OS drop-down list displays all the drives where the operating system is installed, thus helps you select the operating system to migrate.

While you provide the drive mapping information in the Source column, consider the following points:

• You can change a drive that is based on your requirements. Clicking the Source column in the Drive Map area displays list of drives (from C to Z).
• You can decide not to map any non-OS drive by selecting the blank ("---") option from the Source column. However, you cannot select the blank option for a drive where the operating system is installed, map the OS drive. For example, if the Source OS drop-down list shows WINXP(P), and P drive is mapped to C drive, then you cannot select the blank option for P drive. You can anyway map P drive to any other drive.
• CA DMM ensures that your drive mapping is unique. CA DMM automatically swaps the drive mapping information whenever you change an existing drive. For example, when P drive is mapped to C drive and Q drive is mapped to D drive, but you want to map Q drive to C drive, then P drive automatically points to C drive.

You can also set the drive mapping information in the DMM Options file Command-Line field using the command line as follows:

/T C:\MyTemplate.dtf /D (or /SE) C:\MyDNA.dna /DD <WINXP/WIN2K/WIN2000/WINVI>(OS Drive) <DriveMap>

Example

/T C:\MyTemplate.dtf /D (or /SE) C:\MyDNA.dna /DD WINXP(P) P:C,Q:D,R:E

Note: P indicates that the operating system is available in the P drive of the slave disk which represents your source computer. For more information about the Command-Line Switches and Command-Line examples, see the Reference Guide.
