Zone objects
A zone object is any device in a zone, such as the:
• Physical port number or area ID on the switch
• Node World Wide Name (N-WWN)
• Port World Wide Name (P-WWN)
Zone objects identified by port number or area number are specified as a pair of decimal numbers in the
form
d, area
(
d
is the domain ID of the switch and
area
is the area number on that switch).
For example, on the Core Switch 2/64 and the SAN Director 2/128,
4, 46
specifies port 14 in slot
number 3 (domain ID 4, area 46). On fixed-port models,
3,13
specifies port 13 in switch domain ID 3.
When the physical port number specifies a zone object, then all devices connected to that port are in the
zone. If the physical port is an arbitrated loop, then all devices on the loop are part of the zone.
World Wide Names are specified as 8-byte (16-digit) hexadecimal numbers, separated by colons: for
example, 10:00:00:90:69:00:00:8a. When a node name specifies a zone object, all ports on such a
device are in the zone. When a port name specifies a zone object, only the single port is in the zone.
The types of zone objects used to define a zone can be mixed and matched. For example, a zone defined
with the zone objects 2,12; 2,14; 10:00:00:80:33:3f:aa:11 contains the devices connected to domain
2, ports 12 and 14, and a device with the WWN (either node name or port name)
10:00:00:80:33:3f:aa:11 that is connected on the fabric.
Zone aliases
A zone alias is a name assigned to a device or a group of devices. By creating an alias, you can assign
a familiar name to a device or group multiple devices into a single name. This simplifies cumbersome data
entry and allows an intuitive naming structure (such as using
NT_Hosts
to define all NT hosts in the
fabric).
Zone aliases also simplify repetitive entry of zone objects, such as port numbers or a WWN. For example,
you can use the name
Eng
as an alias for
10:00:00:80:33:3f:aa:11
.
A useful convention is to name zones for the initiator they contain. For example, if you use the alias
SRV_MAILSERVER_SLT5
to designate a mail server in PCI slot 5, then the alias for the associated zone
is
ZNE_MAILSERVER_SLT5
. This clearly identifies the server host bus adapter (HBA) associated with the
zone.
Zone configuration naming is more flexible. One configuration should be named
PROD_fabricname
,
where
fabricname
is the name that the fabric has been designated. The purpose of the PROD
configuration is to easily identify the configuration that can be implemented and provide the most generic
services. If other configurations are used for specialized purposes, names such as
BACKUP_A
,
RECOVERY_2
, and
TEST_18jun02
can be used.
Zone configurations
A zone configuration is a group of one or more zones. A zone can be included in more than one zone
configuration. When a zone configuration is in effect, all zones that are members of that configuration are
in effect.
The different types of zone configurations are:
• Defined Configuration, which is the complete set of all zone objects defined in the fabric.
• Effective Configuration, which is a single zone configuration that is currently in effect. The effective
configuration is built when an administrator enables a specified zone configuration.
