Requirements for alternate client backup of RDMs
This topic applies to NetBackup for VMware and VMware raw device mapping mode (RDM).
To use NetBackup Snapshot Client to back up an RDM, note the following:
RDM devices must be configured in physical compatibility mode. You select this mode when you create the RDM. Physical compatibility mode is not configured in NetBackup.
For an introduction to RDM, refer to your VMware documentation. For example, see the following VMware document:
ESX Server 3 Configuration Guide
NetBackup may require certain OS and array configuration, depending on the guest OS and the array. For details, see the disk arrays chapter of the NetBackup Snapshot Client Administrator's Guide.
NetBackup client software must be installed on the virtual machine.
The requirements for the NetBackup for VMware feature (a backup host and the VMware snapshot method) do not apply to backups of RDM disk arrays. To back up RDM disk arrays, you must configure a Snapshot Client alternate client backup.
