SIZE=

Indicates the new larger size (you cannot change to a size smaller than the 
original) of the storage in gigabytes. You can specify size in whole gigabytes 
only. Fractions are not allowed. The value of SIZE can be 2 GB through 2000 GB 
depending on the disk group’s available space. 

WORLD_WIDE_LUN_NAME=

Sets the World Wide LUN Name on unpresented storage (either ACTIVE or 
snapshot). This switch is rejected when issued against storage that is presented to 
a host.

Note:  

This switch is commonly used to allow a host to point to a new version of a 

snapshot by giving the new snapshot the same WWN as the old snapshot.
