Veritas Volume Manager 5.0 Administrator's Guide (September 2006)

49Understanding Veritas Volume Manager
Volume layouts in VxVM
can perform all necessary operations in the “Managed by User” area that includes the top-
level volume and striped plex (for example, resizing the volume, changing the column
width, or adding a column).
System administrators can manipulate the layered volume structure for troubleshooting or
other operations (for example, to place data on specific disks). Layered volumes are used
by VxVM to perform the following tasks and operations:
■ Creating striped-mirrors. (See “Creating a striped-mirror volume” on page 247, and
the vxassist(1M) manual page.)
■ Creating concatenated-mirrors. (See “Creating a concatenated-mirror volume” on
page 241, and the vxassist(1M) manual page.)
■ Online Relayout. (See “Online relayout” on page 50, and the vxrelayout(1M)
and vxassist(1M) manual pages.)
■ RAID-5 subdisk moves. (See the vxsd(1M) manual page.)
■ Snapshots. (See “Administering volume snapshots” on page 295, and the
vxsnap(1M) and
vxassist(1M) manual pages.)
