EBS zoning
For EBS zoning recommendations, see the HP StorageWorks Enterprise Backup Solution design guide
available at http://www.hp.com/go/ebs.
Zone naming
When naming zones:
• Configure and test small zones that are a subset of the larger SAN.
• Use meaningful names for zones and zone member aliases.
• Use a consistent naming scheme for all components.
• Before making zoning changes, save the current configuration.
• If possible, do not make zoning changes when a switch in the fabric is temporarily unavailable.
Naming by identifier type
Define zone member names by using one of the following naming conventions:
• Domain ID and port number
Use the switch domain ID and port number to identify zone members. The zone definition remains
intact when an HBA or controller is replaced by another with a different WWN. However, when
a device is moved to a different port in the fabric, it is no longer a member of the zone.
• WWN
Use the device WWN to uniquely identify zone members. The zone definition remains intact when
the device is moved to a different port or switch in the fabric. However, if an HBA is replaced by
another with a different WWN, you must update the zone definition.
• WWN with domain ID and port number
Use the switch domain ID, port number, and WWN to identify zone members.
Case sensitivity of fabric identifiers
To define an alias naming scheme, consider the case sensitivity of fabric identifiers:
• Case sensitive—Switch alias names
• Not case sensitive—Device connection names
Case sensitivity example
RING_1 and Ring_1 are distinct switch identifiers.
Server naming
Servers are identified by the WWN of the HBA. For server aliases, use the operating system name
and the HBA number. For example, for server WIN01 with one HBA, define the alias as
WIN01_HBA01; for the second HBA, define the alias as WIN01_HBA02.
Storage system naming
Fibre Channel storage systems have a unique WWN for each controller port. When implementing
multiple fabrics, different ports are configured in each fabric.
