The Active System Image

The drd clone command creates a bootable disk containing a copy of the volume group containing the root file system (/). The source of the drd clone command is the LVM volume group or VxVM disk group containing the root (/) and boot (/stand) file systems. For a system with an LVM root, the source does not need to reside on a single physical disk. For a system with a VxVM root, all volumes in the root disk group must reside on every physical disk in the root group. Thus, each disk must be a mirror of every other disk. The target must be a single physical disk large enough to hold all volumes in the root group. In addition, a mirror for the target may be specified. For more details, see the Using the Dynamic Root Disk Toolset white paper, available at: http://docs.hp.com/en/oshpux11iv2.html#Dynamic%20Root%20Disk

Because the drd clone operation clones a single group, systems with file systems to be patched must not reside in multiple volume groups. (For example, if /stand resides in vg00 and /var resides in vg01, the system is not appropriate for DRD.)

For additional information about source and target disks, see the drd-clone (1M) manpage (man drd-clone) and the Using the Dynamic Root Disk Toolset white paper, available at: http://docs.hp.com/en/oshpux11iv2.html#Dynamic%20Root%20Disk.
