Figure 1-19 Example of a Striped-Mirrored Layered Volume
System administrators may need to manipulate the layered volume
structure for troubleshooting or other operations (for example, to place
data on specific disks). Layered volumes are used by Volume Manager to
perform these tasks and operations:
• striped-mirrors (see the vxassist(1M) manual page)
• concatenated mirrors (see the vxassist(1M) manual page)
• Online Relayout (see the vxrelayout(1M) and vxassist(1M)
manual pages)
• RAID-5 subdisk moves (see the vxsd(1M) manual page)
• RAID-5 snapshot (see the vxassist(1M) manual page)
