Resolution

To create a volume utilizing all the remaining free space within a disk group, use the following command:
 
#vxassist -g dg_name make vol_name ` vxassist -g dg_name -p maxsize layout=xxxxdisks_name` layout=xxxx disks_name
 
where "xxxx" is the volume layout such as concat,stripe or raid5.

For example,
 
#vxassist -g newdg02 make testvol `vxassist -g newdg02 -p maxsize layout=concat newdg0203` layout=concat newdg0203


The above command can be broken into two parts:

1.  Get the maximum size with the given attributes:
 
#vxassist -g dg_name -p maxsize layout=xxxx disks_name
 
2.  Create the volume:
 
#vxassist -g dg_name make vol_name size layout=xxxxdisks_name
