Disk tasks
The following disk tasks are supported:
■ Changing the default disk format
■ Restoring CDS disk labels
Changing the default disk format
When disks are put under VxVM control, they are formatted with the default
cdsdisk layout. This happens during the following operations:
■ Initialization of disks
■ Encapsulation of disks with existing partitions or slices (Linux and Solaris
systems)
■ Conversion of LVM disks (AIX, HP-UX and Linux systems)
You can override this behavior by changing the settings in the system defaults
files. For example, you can change the default format to sliced for disk
initialization by modifying the definition of the format attribute in the
/etc/default/vxdisk defaults file.
To change the default format for disk encapsulation or LVM disk conversion
■ Edit the /etc/default/vxencap defaults file, and change the definition of the
format attribute.
See “Defaults files” on page 471.

■ Platform block
