DEFINE STGPOOL (Define a storage pool)
Use this command
to define a primary storage pool, copy storage pool,
or an active-data pool. A primary storage pool provides a
destination
for backup files, archive files, or files migrated from
client nodes. A
copy storage pool provides a destination for backup
copies of files that
are in primary storage pools. An active-data pool
provides a destination
for active versions of backup data that are in primary
storage pools.
All volumes in a storage pool belong to the same device
class. Random
access storage pools use the DISK device type. After you
define a random
access storage pool, you must define volumes for the pool
to create
storage space.
Sequential access storage pools use device classes that
you define for
tape devices, optical devices, files on disk (FILE device
type), and
storage on another server (SERVER device type). To create
storage space
in a sequential access storage pool, you must allow
scratch volumes for
the pool when you define or update it, or define volumes
for the pool
after you define the pool. You can also do both.
The DEFINE STGPOOL command takes four forms:
* Defining a
primary storage pool assigned to random access devices
* Defining a
primary storage pool assigned to sequential access devices
* Defining a copy
storage pool (always assigned to sequential access
devices)
* Defining an
active-data pool (always assigned to sequential access
devices)
The syntax and
parameters for each form are defined separately.
