Vmprocessvmwithprdm

Use this option to control whether full VMware virtual machine backups are processed if the virtual machine has one or more raw device mapping (RDM) volumes provisioned in physical-compatibility mode (pRDM).

pRDM volumes do not support snapshots. Any pRDM volumes found on a virtual machine are not processed as part of the backup operation. When the virtual machine is restored, the backup-archive client recovers the virtual machine, and only the volumes that participated in snapshot operations are restored. Configuration information and content of the pRDM volumes is not preserved in the information stored on the IBM Spectrum Protect™ server. Users must re-create the pRDM volumes on the restored machine.

This option does not apply to virtual machines that have one or more RDM volumes that are provisioned in virtual-compatibility mode (vRDM). Because vRDM volumes do support snapshot operations, they are included in a full VMware virtual machine backup.

If the virtual machine also contains one or more independent disks, use the vmprocessvmwithindependent option to control whether the client backs up any files on the virtual machine if an independent disk is present.

This feature is available only if the client operates as a data mover for IBM Spectrum Protect for Virtual Environments: Data Protection for VMware.

This option is only valid for VMware backups and does not pertain to Microsoft Hyper-V backups.

Supported Clients

This option is valid for Windows and Linux clients that are configured as a VMware backup server. The server can also define this option.

Options File

Windows operating systems Place this option in the client options file (dsm.opt) or on the command line

Linux operating systems Place this option in the client options file (dsm.opt), in the client system options file (dsm.sys), or on the command line.

Parameters

No: The backup of the virtual machine fails if one or more pRDM volumes are detected. No is the default.

Yes: Virtual machines that contain one or more raw device mapping (RDM) volumes that are provisioned in physical-compatibility mode (pRDM) are backed up. However, the pRDM volumes are not processed as part of the virtual machine backup operation.; If the virtual machine also contains one or more independent disks, the vmprocessvmwithindependentdisk option must also be specified.
