You can choose to map the new volumes immediately as part of the volume create wizard by
clicking Create and Map to Host. It will guide you through the Map to Host wizard described
in 6.3, “Mapping a volume to the host” on page 279.
6.1.4 Creating a thin-mirror volume
A thin-mirror volume allows you to allocate the required space on demand (described in 6.1.2,
“Creating a thin-provisioned volume” on page 260) and have several copies of a volume
(described in 6.1.3, “Creating a mirrored volume” on page 262) available.
In the following example, we create a thin-mirror volume where one copy of the mirror is
physically located internally to the IBM Flex System V7000 Storage Node disks and the other
copy is located on an IBM DS4000 disk array system.
