Set the optimized space snapshot autogrow parameter to ON. i.e.

vxcache -g test1 set autogrow=on snap_voltest1-C01

Verify the parameter setting:

vxprint -mg test1 snap_voltest1-C01 |grep autogrow

To check and monitor the size of the cache volume use the 'vxcache' command as shown below.

vxcache -g test1 stat snap_voltest1-C01
