3 Managing storage resources in a SAN
environment
This module describes managing storage resources such as THP/Smart pools and volumes in a Storage
Area Network (SAN).
Creating and deleting volumes
This module describes how to create volumes (including LUSE volumes), and delete unallocated
volumes.
About creating volumes
You create volumes, then allocate them to a host.
You create volumes by using the available space in a THP/Smart pool or parity group. You can then
access the volumes when you are ready to allocate them to a host. If, while allocating volumes to a
host, no volumes match the specified requirements, volumes are automatically created using the
available space. Note that when a basic volume is created, the volume is also formatted at the same
time.
Newly created volumes are included in the list of Open-Unallocated volumes until you allocate them
to a host.
Because creating volumes takes time, you should create volumes in advance.
