Working with THP V-VOLs
About THP V-VOLs
Thin Provisioning requires the use of THP V-VOLs, which are virtual volumes with no physical
memory space. In Thin Provisioning, multiple THP V-VOLs can be created.
A THP V-VOL is a volume in a thin provisioning storage system. It is the virtual volume from a THP
pool. Data in the THP pool is used via a THP V-VOL. A THP V-VOL is a virtual LU to some hosts.
