Figure 2-3shows the two disks after cloning. Both disks contain the system image. The image on the target disk is the inactive system image.

The DRD clone operation will have some impact on the booted system's I/O resources, particularly if the source disk is on the same SCSI chain as the target disk. DRD's performance is similar to system performance when using Ignite to create recovery images, which many system administrators find acceptable.

Figure 2-3 Disk Configurations After Cloning

After running drd clone, you have identical system images on the system disk and the target disk. The image on the system disk is the active system image. The image on the target disk is the inactive system image.

The drd clone command returns the following values:

0Success

1Error

2Warning

Here is an example of creating a clone from a HP-UX 11i v3 system to a storage area network (SAN) disk. First, Example 2-8displays the output of the following drd clone command:

# /opt/drd/bin/drd clone -t /dev/disk/disk14 -x overwrite=true
