Displaying and changing default disk layout attributes

To display or change the default values for initializing disks, select menu item

21(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 for more information.

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.

Caution: Initialization does not preserve data on disks.

When initializing multiple disks at one time, it is possible to exclude certain disks or certain controllers. To exclude disks, list the names of the disks to be excluded in the file /etc/vx/disks.exclude before the initialization. You can exclude all disks on specific controllers from initialization by listing those controllers in the file /etc/vx/cntrls.exclude.

To initialize disks for VxVM use

1Select menu item 1 (Add or initialize one or more disks) from the vxdiskadm main menu.

Use this operation to add one or more disks to a disk group. You can add the selected disks to an existing disk group or to a new disk group that will be created as a part of the operation. The selected disks may also be added to a disk group as spares. Or they may be added as nohotuses to be excluded from hot-relocation use. The selected disks may also be initialized without adding them to a disk group leaving the
