Figure 5-2 shows a recovery log consisting of three volumes (log01.dsm through
log03.dsm). The volumes could exist on the same disk, or be spread across any
number of actual disk drives.

5.2.2 Defining recovery log volumes
There are two ways to allocate a new recovery log volume. The most common
and easiest method to use is the administrative
define logvolume command (or
equivalent Administration Center GUI function) specifying the FORMATSIZE
option.
The second method is to use the DSMFMT utility command (from a shell or
command window) to allocate the volume file. Then use the
define logvolume
command to define the recovery log volume to Tivoli Storage Manager (without
specifying the FORMATSIZE option). For further information about the DSMFMT
utility, see the Administrator’s Reference for your server platform.
