Displaying or changing default disk layout attributes
To display or change the default values for initializing the layout of disks
◆
Select Change/display the default disk layout from the vxdiskadm main
menu. For disk initialization, you can change the default format and the
default length of the private region. The attribute settings for initializing
disks are stored in the file, /etc/default/vxdisk.
See the vxdisk(1M) manual page.
Adding a disk to VxVM
Formatted disks being placed under VxVM control may be new or previously used
outside VxVM. The set of disks can consist of all disks on the system, all disks on
a controller, selected disks, or a combination of these.
Depending on the circumstances, all of the disks may not be processed in the same
way.
When initializing multiple disks at one time, it is possible to exclude certain disks
or certain controllers.
To exclude a device from the view of VxVM, select Prevent
multipathing/Suppress devices from VxVM’s view from the vxdiskadm main
menu.
Warning: Initialization does not preserve the existing data on the disks.
See “Disabling multi-pathing and making devices invisible to VxVM” on page 152.
To initialize disks for VxVM use

Select Add or initialize one or more disks from the vxdiskadm main

[<pattern-list>,all,list,q,?]
The pattern-list can be a single disk, or a series of disks and/or controllers
(with optional targets). If pattern-list consists of multiple items, separate
them using white space. For example, specify four disks at separate target
IDs on controller 3 as follows:
