Understanding ISP
Intelligent Storage Provisioning (ISP) allows you to organize and manage your
physical storage by creating virtual storage devices, application volumes. You
can use such volumes in the same way as traditional volumes in Veritas
TM
Volume Manager (VxVM) by Symantec.
ISP creates application volumes from available storage with the capabilities you
specify. It selects storage by consulting the externally-defined rule base for
creating volumes, and compares this with the properties of the storage that is
available.
ISP provides the following functionality:
■ Creation and removal of application volumes.
■ Organizing storage by grouping into storage pools.
■ Resizing a volume while it is online.
■ Moving or evacuating subdisks of a volume.
■ Adding mirrors and columns to a volume while it is online.
■ Removing mirrors and columns from a volume while it is online.
■ Relocating a subdisk of a volume while it is online.
■ Changing the capabilities of a volume while it is online.
■ Creating volume snapshots using software or hardware.
■ Reallocation of storage to preserve the capabilities of a volume.
ISP is capable of understanding Storage Area Network (SAN) topology and of
efficiently using the available intelligent storage. ISP interacts with other
Veritas components, where these are available, such as the Veritas Array
Integration Layer (VAIL) and the SAN Access Layer (SAL), to take appropriate
actions when configuring intelligent storage in a SAN environment.
See “Configuring ISP to work with SAL” on page 215.
