Accessing a Volume
182 VERITAS Volume Manager Administrator’s Guide
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 make volume length layout=raid5 init=zero
Note You cannot use the -b option to make this operation a background task.
Accessing a Volume
As soon as a volume has been created and initialized, it is available for use as a virtual
disk partition by the operating system for the creation of a file system, or by application
programs such as relational databases and other data management software.
Creatinga volume inthe disk grouprootdg sets up blockand character (raw)device files
that can be used to access the volume:
/dev/vx/dsk/volume—block device file for volume
/dev/vx/rdsk/volume—character device file for volume
For volumes indisk groups other than rootdg, the pathnames include adirectorynamed
for the disk group:
/dev/vx/dsk/diskgroup/volume—block device file for volume
/dev/vx/rdsk/diskgroup/volume—character device file for volume
Use the appropriate device node to create, mount and repair file systems, and to lay out
databases that require raw partitions.
