[-default_slice_flag {y|n}]
If set to y (default), then members of the storage pool may be
sliced when space is dispensed from the storage pool. If set to n,
members of the storage pool will not be sliced when space is
dispensed from the storage pool and the volumes specified
cannot be built on a slice.
[-is_dynamic {y|n}]
Allows a system-defined storage pool to automatically
extend/shrink member volumes.
Note: The -is_dynamic option is for system-defined storage pools only.
[-is_greedy {y|n}]
If set to y, then the system-defined storage pool attempts to create
new member volumes before using space from existing member
volumes. A storage pool that is not greedy (set to n), consumes all
of the space existing in the storage pool before trying to add
additional member volumes. A y or n value must be specified
when modifying a system-defined storage pool.
Note: The -is_greedy option is for system-defined storage pools only.
-delete {<name>|id=<id>}
Deletes a storage pool. Storage pools cannot be deleted if any
members are in use. After deletion, the storage pool no longer exists
on the system, however, members of the storage pool are not deleted.
[-deep]
Deletes the storage pool and also recursively deletes each
member of the storage pool. Each storage pool member is deleted
unless it is in use or is a disk volume.
-xtend {<name>|id=<id>} -volumes <volume_name>
[,<volume_name>,...]
Adds one or more unused volumes to a storage pool. If the
default_slice_value is set to n, member volumes cannot contain slice
volumes (for compatibility with TimeFinder/FS).
Note: Extending a storage pool by volume is for user-defined storage pools
only.
-xtend {<name>|id=<id>} -size <integer> [M|G]
Extends the specified storage pool with one or more volumes of the
