Chapter 2, Administering Disks

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.

Initialize disks for VxVM use as follows:

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

vxdiskadm main menu.

2. At the following prompt, enter the disk device name of the disk to be added to VxVM

control (or enter list for a list of disks):

Add or initialize disks

Menu: VolumeManager/Disk/AddDisks

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 disks available for use as replacement

disks.
