Converts all non-CDS disks in the disk group into CDS disks.alldisks
Specifies a single disk for conversion. You would use this option
under the following circumstances:
If a disk in the non-CDS disk group has cross-platform
exposure, you may want other VxVM nodes to recognize the
disk, but not to assume that it is available for initialization.
If the native Logical Volume Manager (LVM) that is provided
by the operating system needs to recognize CDS disks, but it
is not required to initialize or manage these disks.
Your intention is to move the disk into an existing CDS disk
group.
disk
The conversion involves evacuating objects from the disk, reinitializing the
disk, and relocating objects back to disk. You can specify the -o novolstop
option to perform the conversion on-line (that is, while access to the disk
continues). If the -o novolstop option is not specified, stop any applications
that are accessing the disks, and perform the conversion off-line.
Warning: Specifying the -o novolstop option can greatly increase the amount
of time that is required to perform conversion.
Before you use the vxcdsconvert command, make sure you understand its
options, attributes, and keywords.
See the vxcdsconvert(1M) manual page.

To convert a non-CDS disk group to a CDS disk group
1
If the disk group contains one or more disks that you do not want to convert
to CDS disks, use the vxdg move or vxdg split command to move the disks
out of the disk group.
2
The disk group to be converted must have the following characteristics:
No dissociated or disabled objects.
No sparse plexes.
No volumes requiring recovery.
No volumes with pending snapshot operations.
No objects in an error state.
