20.2.7 Cloning backup images between partitions Cloning refers to creating a backup image of one machine or partition and installing a different machine or partition with that same image. This section demonstrates the basic tasks required to do the following operations: Identify resources that may need to be supported for the cloning process. Perform a system backup to a device assigned to the partition: - Perform a basic boot and install using a DVD backup made from another partition. Perform a system backup to a remote device assigned to another partition: - Perform a network boot. - Perform a basic installation remotely across the network using a DVD backup made from another partition. Note: There are other variations to prepare for needed support or to enable support at the time of install. However, these examples can be complicated and relate to very specific scenarios. The processes described here are the most direct and the least complicated. Resource identification When cloning, it is important to remember that an image from the source machine or partition must have all of the needed device driver filesets and kernel filesets installed to support the hardware of the new machine or partition. In a partitioned environment, the need to identify the required device driver and kernel filesets is greatly reduced. Device driver filesets The essential device drivers needed to support each partition are the same across all of the partitions, because each partition exists on the same physical machine. Examples of essential device drivers might be filesets to support SCSI disk drives or the I/O bus. However, each partition can have additional I/O slots assigned to it beyond the minimal requirements for defining a partition. These I/O slots may have adapter cards used to attach external devices. Various types of Ethernet adapters, or even differential SCSI adapters used to attach tape libraries, are examples of how these I/O slot allocations can be used. Each I/O component has an associated device driver. Chapter 20. Bare Machine Recovery 657
