Creating a CDS disk group by using vxdg init
To create a CDS disk group by using the vxdg init command
Note: The disk group version must be 110 or greater.
◆ Type the following command:
# vxdg init diskgroup disklist [cds={on|off}]
The format defaults to a CDS disk group, unless this is overridden by the
/etc/default/vxdg file, or by specifying the cds argument.
See the vxdg(1M) manual page for more information.
Creating a CDS disk group by using vxdiskadm
You cannot create a CDS disk group when encapsulating an existing disk, or
when converting an LVM volume.
When initializing a disk, if the target disk group is an existing CDS disk group,
vxdiskadm will only allow the disk to be initialized as a CDS disk. If the target
disk group is a non-CDS disk group, the disk can be initialized as either a CDS
disk or a non-CDS disk.
If you use the
vxdiskadm command to initialize a disk into an existing CDS disk
group, the disk must have be added with the
cdsdisk format.
The CDS attribute for the disk group remains unchanged by this procedure.
To create a CDS disk group by using the vxdiskadm command
◆ Run the vxdiskadm command, and select the “Add or initialize one
or more disks” item from the main menu. Specify that the disk group
should be a CDS disk group when prompted.
