If DRL is enabled on a newly-created volume without specifying a log or map size, default values are used. You can use the command line attributes
loglen in conjunction with the
vxmake commands to set the DRL map and DRL log sizes. The attributes can be used independently, or they can be combined.
You can change the DRL map size and DRL log size only when the volume is disabled and the DRL maps are not in use. Changes can be made to the DRL map size only for volumes in a CDS disk group.
logmap_len attribute specifies the required size, in bytes, for the DRL log. It cannot be greater than the number of bytes available in the map on the disk.
