Veritas Storage Foundation Portable Data Containers: Cross-Platform Data Sharing 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

In the following example, the disk group, anodg, and all its disks are converted
to CDS while keeping its volumes are still online:
# vxcdsconvert -g anodg -o novolstop group \
move_subdisks_ok=yes evac_subdisks_ok=yes \
evac_disk_list=anodg11,anodg12,anodg13,anodg14
The evac_disk_list attrinute specifies a list of disks (nodg11 through anodg14)
to which subdisks can be evacuated to disks if required.
Before you use the vxcdsconvert command, make sure you understand its
options, attributes, and keywords.
See the vxcdsconvert(1M) manual page.
Side effects of conversion
Conversion has the following side effects:
■ Non-CDS disk group are upgraded by using the vxdg upgrade command. If
the disk group was originally created by the conversion of an LVM volume
group (VG), rolling back to the original LVM VG is not possible. If you decide
to go through with the conversion, the rollback records for the disk group will
be removed, so that an accidental rollback to an LVM VG cannot be done.
■ Stopped, but startable, volumes are started for the duration of the conversion.
■ Any volumes or other objects in the disk group that were created with the
layout=diskalign attribute specified can no longer be disk aligned.
■ Encapsulated disks may lose the ability to be unencapsulated.
■ Performance may be degraded because data may have migrated to different
regions of a disk, or to different disks.
Verifying licensing
The ability to create or import a CDS disk group is controlled by a CDS license.
CDS licenses are included as part of the Veritas Storage Foundation license.
To verify the CDS enabling license
■ Type the following command:
# vxlicrep
Verify the following line in the output:
Cross-platform Data Sharing = Enabled
