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.

Converting non-CDS disks to CDS disks

Note: The disks must be of type of auto in order to be re-initialized as CDS disks.

To convert non-CDS disks to CDS disks

If the conversion is not going to performed on-line (that is, while access to

the disk group continues), stop any applications that are accessing the disks.

Type one of the following forms of the CDS conversion utility (vxcdsconvert)

to convert non-CDS disks to CDS disks.

# vxcdsconvert -g diskgroup [-A] [-d defaults_file] \

[-o novolstop] disk name [attribute=value] ...

# vxcdsconvert -g diskgroup [-A] [-d defaults_file] \

[-o novolstop] alldisks [attribute=value] ...

The alldisks and disk keywords have the following effect

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.
