Note: To bring LVM disks under VxVM control, use the Migration Utilities.
See the Veritas Volume Manager Migration Guide for details.
15 At the following prompt, indicate whether you want to continue to initialize
more disks (y) or return to the vxdiskadm main menu (n):
Add or initialize other disks? [y,n,q,?] (default: n)
See “Displaying and changing default disk layout attributes” on page 97 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 97 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).
Using vxdiskadd to place a disk under control of VxVM
As an alternative to vxdiskadm, you can use the vxdiskadd command to put a
disk under VxVM control. For example, to initialize the second disk on the first
controller, use the following command:
# vxdiskadd c0t1d0
The vxdiskadd command examines your disk to determine whether it has been
initialized and also checks for disks that have been added to VxVM, and for
other conditions.
