Accessing a Volume
222 VERITAS Volume Manager Administrator’s Guide
Initializing and Starting a Volume Created Using vxmake
A volume may be initialized by running the vxvol command if the volume was created
by the vxmake command and has not yet been initialized, or if the volume has been set to
an uninitialized state.
To initialize and start a volume, use the following command:
# vxvol [-g diskgroup] start volume
The following command can be used to enable a volume without initializing it:
# vxvol [-g diskgroup] init enable volume
This allows you to restore data on the volume from a backup before using the following
command to make the volume fully active:
# vxvol [-g diskgroup] init active volume
If you want to zero out the contents of an entire volume, use this command to initialize it:
# vxvol [-g diskgroup] init zero volume
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.
Creating a volume in a disk group sets up block and character (raw) device files that can
be used to access the volume:
/dev/vx/dsk/diskgroup/volume block device file for volume
/dev/vx/rdsk/diskgroup/volume character device file for volume
The pathnames include a directory named for the disk group. Use the appropriate device
node to create, mount and repair file systems, and to lay out databases that require raw
partitions.
Note As the rootdg disk group no longer has special significance, VxVM only creates
volume device nodes for this disk group in the /dev/vx/dsk/rootdg and
/dev/vx/rdsk/rootdg directories. VxVM does not create device nodes in the
/dev/vx/dsk or /dev/vx/rdsk directories for the rootdg disk group.
