◆ Manufacturer
◆ Model type
◆ Physical location, such as rack number, frame number, floor, building, or site
◆ Hardware RAID configuration
◆ Failover properties
◆ Performance properties
Note You can use the annotation service, provided in the VEA graphical user interface, to create
and delete storage attributes.
Attributes may be used to capture information about special features that storage possesses, such
as:
◆ Hardware-supported cloning, such as EMC Business Continuity Volumes (BCV)
◆ Hardware-supported replication, such as the EMC Symmetrix Remote Data Facility (SRDF)
◆ Hardware redundancy, such as mirrored parity, and caching
It should only be necessary to enter such information manually if VxVM cannot discover it
automatically. An example of a user-defined attribute is physical location.
Note Attribute names and their string values are case sensitive. You can use the vxvoladm
listattrs command to discover the correct spelling of LUN attribute names.
Storage Pool
A storage pool is defined within a disk group in VxVM for use by ISP. A storage pool is a
policy-based container for LUNs and volumes. This means that the templates, capabilities and
policies that are associated with a storage pool define how storage is organized within the pool.
For convenience, storage pool definitions are provided that include a number of associated
templates that can be used for different purposes. See “Storage Pools” on page 171 for details of the
storage pool definitions that are provided.
Two types of storage pool are defined: data pools and clone pools. These are described in the
following sections.
Data Pool
The first storage pool that is created within a disk group. All other storage pools that are
subsequently created within a disk group are clone pools.
