cdsdisk The disk is formatted as a Cross-platform Data Sharing (CDS) disk that is

suitable for moving between different operating systems. This is the default

format for disks that are not used to boot the system.Typically, most disks

on a system are conﬁgured as this disk type. However, it is not a suitable

format for boot, root or swap disks, for mirrors or hot-relocation spares of

such disks, or for EFI disks.

hpdisk The disk is formatted as a simple disk. This format can be applied to disks

that are used to boot the system. The disk can be converted to a CDS disk if

it was not initialized for use as a boot disk.

See the vxcdsconvert(1M) manual page for information about the utility that you can use to

convert disks to the cdsdisk format.

By default, auto-conﬁgured disks are formatted as cdsdisk disks when they are initialized

for use with VxVM. You can change the default format by using the vxdiskadm(1M) command

to update the /etc/default/vxdisk defaults ﬁle as described in “Displaying and Changing

Default Disk Layout Attributes” on page 82. See the vxdisk(1M) manual page for details of

the usage of this ﬁle, and for more information about disk types and their conﬁguration.
