See “Displaying and changing default disk layout attributes” on page 95 for details of how
to change the default layout that is used to initialize disks.
Reinitializing a disk
You can reinitialize a disk that has previously been initialized for use by VxVM by putting
it under VxVM control as you would a new disk. See “Adding a disk to VxVM” on
page 95 for details.
Caution: Reinitialization does not preserve data on the disk. If you want to reinitialize the
disk, make sure that it does not contain data that should be preserved.
If the disk you want to add has previously been under LVM control, you can preserve the
data it contains on a VxVM disk by the process of conversion (see the Veritas Volume
Manager Migration Guide for more details).
