7.2  Creating volumes
This section focuses on the use of the Create Volumes menu to create Basic and Mirrored 
volumes in a system with standard topology. Volume creation is available on the following 
volume classes:
/SM590000Basic
/SM590000Mirrored
/SM590000HyperSwap
/SM590000Custom
Note: Consider the following points:
/SM590000A Basic volume is a volume that has only one physical copy, uses storage that is 
allocated from a single pool on one site, and uses read/write cache mode. 
/SM590000A Mirrored volume is a volume with two physical copies, where each volume copy can 
belong to a different storage pool.
/SM590000A Custom volume (in the context of this menu) is a Basic or Mirrored volume with values 
of some of its parameters that are changed from the defaults.
/SM590000The Create Volumes window also provides (by way of the Capacity Savings parameter) 
the ability to change the default provisioning of a Basic or Mirrored Volume to 
Thin-provisioned or Compressed. For more information, see 7.2.3, “Capacity savings 
option” on page 265.
