be removed from VxVM management. To remove non- HDLM devices from
VxVM management, see (2) Removing Devices from VxVM on a Controller
Basis or (3) Removing Devices From VxVM on a Path Basis of
3.13.3 Removing Devices from VxVM. To apply the settings performed in

3. Create a disk group by referring to the VxVM documentation.
An HDLM device can be added to VxVM as a disk of the
sliced type or the
cdsdisk type.
Note
Do not add an HDLM device to a disk group registered as
bootdg. Also, do
not register a disk group containing an HDLM device in
bootdg.
4. If you are using Sun Cluster, register the created disk group into a Sun Cluster
disk device group.
For details, see 3.13.5 Linking VxVM and Sun Cluster.
3.13.2 Creating VxVM Volumes
A VxVM volume can be created by using the vxassist (or vxmake) command or
Veritas Enterprise Administrator. For details, refer to the VxVM documentation.
Note
If you have created a volume for a disk group registered in Sun Cluster, register
the change made to the VxVM disk group configuration into Sun Cluster. For
details, see 3.13.5 Linking VxVM and Sun Cluster.
When creating a VxVM volume, a block device file and character device file for
accessing volumes will be created:
Block device file
/dev/vx/dsk/disk-group-name/volume-name
Character device file
/dev/vx/rdsk/disk-group-name/volume-name
When creating a file system, mounting a file system, or specifying the layout of a
database using a raw partition, use the device file appropriate to each situation.
In the following example, the commands create and mount a file system.
# newfs /dev/vx/rdsk/dlmdg/vol01
# mount /dev/vx/dsk/dlmdg/vol01 /mnt
