If you create a volume using the vxassist command, vxassist initializes and starts the volume automatically unless you specify the attribute init=none.
When creating a volume, you can make it immediately available for use by specifying the -b option to the vxassist command, as shown here:
# vxassist -b [-g diskgroup] make volume length layout=mirror
The -b option makes VxVM carry out any required initialization as a background task. It also greatly speeds up the creation of striped volumes by initializing the columns in parallel.
As an alternative to the -b option, you can specify the init=active attribute to make a new volume immediately available for use. In this example, init=active is specified to prevent VxVM from synchronizing the empty data plexes of a new mirrored volume:
# vxassist [-g diskgroup] make volume length layout=mirror \ init=active
This command writes zeroes to the entire length of the volume and to any log plexes. It then makes the volume active. You can also zero out a volume by specifying the attribute init=zero to vxassist, as shown in this example:
# vxassist [-g diskgroup] make volume length layout=raid5 \ init=zero
You cannot use the -b option to make this operation a background task.
