Create a volume for the log files and an additional volume for each database.
To create a dynamic volume from the VEA console
Select a profile if prompted and connect to the appropriate host.
Make sure the appropriate disk group name appears in the Group name drop-down list.
For example, Exch-DG1.
For Site Preference, leave the setting as Siteless (the default).
Specify automatic disk selection (the default) or manual disk selection. To manually select disks, use the Add button to move the appropriate disks to the Selected disks list. Manual selection of disks is recommended.
You may also check Disable Track Alignment to disable track alignment for the volume. Disabling Track Alignment means that the volume does not store blocks of data in alignment with the boundaries of the physical track of the disk.
Enter the volume name (for example, DB1-tlogs).
Enter the size.
Select the layout.
Select the appropriate mirror options.
If you are assigning a drive letter to a replication volume in an Exchange 2010 DAG, use the same drive letter as the volume on the active node.
To create a volume from the command line
vxassist [-b] -gExch-DG1 make DB1-tlogs 200 DriveLetter=I
This example command will create a 200 MB volume named DB1-tlogs on drive letter I: in the Exch-DG1 dynamic disk group.
