Default Zone, Zone Sets

Page 139 highlights

Fabric Zoning The advantage of identifying a zone member by port number is that if the HBA on an attached device fails, you do not have to identify the member with the WWN of the replacement HBA. A disadvantage of port zoning is that someone may rearrange cable connections to ports (because of port failures or other reasons) and inadvertently allow devices to communicate that should not have access to each other. Note: If a managed product's Domain ID changes, you must reconfigure all zones that contained the managed product's port as a zone member. HP recommends assigning unique preferred Domain ID's to each switch in the fabric using the Configure Switch Parameters dialog box in the Product Manager. Default Zone A default zone consists of all devices that have not been configured as members of a zone in a currently-active zone set. Here are some important points to remember about zone sets: ■ While viewing the Fabrics tab, you can enable or disable the default zone separately from the active zone set by selecting the Configure Default Zone option from the Advanced Zoning options in the Configure menu. Enabling the default zone allows all devices and ports not configured as members of the active zone set to communicate. If the default zone is disabled, these ports and devices cannot communicate. ■ When no zone set is activated, then all devices are considered to be in the default zone. ■ If a zone set is active, then all connected devices that are not included as a members of a zone in the active zone set are included in the default zone. Zone Sets A zone set is a group of zones that you can activate or deactivate as a single entity across all managed products in either a single switch or a multiswitch fabric. Only one zone set can be active at one time. Devices that are members of zones in the zone set can only communicate with members of zones in the same zone set. However, devices can be included as members of more than one zone set. By activating a zone set, you are making all zones in the set active. Refer to Table 5 on page 144 for details on the number of zones and zone members that you can configure in a zone set and the number of zone sets that you can configure in the HAFM zoning library.

Fabric Zoning
139
High Availability Fabric Manager User Guide
The advantage of identifying a zone member by port number is that if the HBA on
an attached device fails, you do not have to identify the member with the WWN of
the replacement HBA.
A disadvantage of port zoning is that someone may rearrange cable connections to
ports (because of port failures or other reasons) and inadvertently allow devices to
communicate that should not have access to each other.
Note:
If a managed product’s Domain ID changes, you must reconfigure all zones that
contained the managed product’s port as a zone member. HP recommends assigning
unique preferred Domain ID’s to each switch in the fabric using the
Configure Switch
Parameters
dialog box in the Product Manager.
Default Zone
A default zone consists of all devices that have not been configured as members of
a zone in a currently-active zone set. Here are some important points to remember
about zone sets:
While viewing the
Fabrics
tab, you can enable or disable the default zone
separately from the active zone set by selecting the
Configure Default Zone
option from the
Advanced Zoning
options in the
Configure
menu. Enabling
the default zone allows all devices and ports not configured as members of the
active zone set to communicate. If the default zone is disabled, these ports and
devices cannot communicate.
When no zone set is activated, then all devices are considered to be in the
default zone.
If a zone set is active, then all connected devices that are not included as a
members of a zone in the active zone set are included in the default zone.
Zone Sets
A zone set is a group of zones that you can activate or deactivate as a single entity
across all managed products in either a single switch or a multiswitch fabric. Only
one zone set can be active at one time. Devices that are members of zones in the
zone set can only communicate with members of zones in the same zone set.
However, devices can be included as members of more than one zone set. By
activating a zone set, you are making all zones in the set active.
Refer to
Table 5
on page 144 for details on the number of zones and zone
members that you can configure in a zone set and the number of zone sets that you
can configure in the HAFM zoning library.
