The format defaults to cdsdisk unless this is overridden by the

/etc/default/vxdisk file, or by specifying the disk format as an argument

to the format attribute.

See “Defaults files” on page 28.

See the vxdisksetup(1M) manual page.

Creating CDS disks by using vxdiskadm

To create a CDS disk by using the vxdiskadm command

■ Run the vxdiskadm command, and select the “Add or initialize one or

more disks” item from the main menu. You are prompted to specify the format.

Warning: On CDS disks, the CDS information occupies the first sector of that

disk, and there is no fdisk partition information. Attempting to create an

fdisk partition (for example, by using the fdisk or format commands) erases

the CDS information, and can cause data corruption.

Creating CDS disks from initialized VxVM disks

How you create a CDS disk depends on the current state of the disk, as follows:

■ Creating a CDS disk from a disk that is not in a disk group

■ Creating a CDS disk from a disk that is already in a disk group

Creating a CDS disk from a disk that is not in a disk group

To create a CDS disk from a disk that is not in a disk group

Run the following command to remove the VM disk format for the disk:

# vxdiskunsetup disk

This is necessary as non-auto types cannot be reinitialized by vxdisksetup.

If the disk is listed in the /etc/vx/darecs file, remove its disk access (DA)

record using the command:

# vxdisk rm disk

(Disk access records that cannot be configured by scanning the disks are

stored in an ordinary file, /etc/vx/darecs, in the root file system. Refer to

the vxintro(1M) manual page for more information.)
