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.

You can verify the CDS enabling license by running the vxlicrep command, and looking for this

line in the output:

Cross-platform Data Sharing = Enabled

Defaults Files

Several system defaults files in the /etc/default directory are of importance for specifying the

alignment of VxVM objects, the initialization or encapsulation of VM disks, the conversion of

LVM disks, and the conversion of disk groups and their disks to the CDS-compatible format:

◆ /etc/default/vxassist

Specifies default values for the following parameters to the vxcdsconvert command that have

an effect on the alignment of VxVM objects: dgalign_checking, diskalign, and

nodiskalign. See “Object Alignment During Volume Creation” on page 24, and the

vxassist(1M) manual page for more information.

◆ /etc/default/vxcdsconvert

Specifies default values for the following parameters to the vxcdsconvert command:

evac_disk_list, evac_subdisks_ok, min_split_size, move_subdisks_ok,

privlen, and split_subdisks_ok. The following is a sample vxcdsconvert defaults

file:

evac_subdisks_ok=no

min_split_size=64k

move_subdisks_ok=yes

privlen=2048

split_subdisks_ok=move

An alternate defaults file can be specified by using the -d option with the vxcdsconvert

command. See the vxcdsconvert(1M) manual page for more information.
