Connecting Ports Through Hard Zoning
A Hard Zone can be used to add a separate 126 AL_PAs that operate in isolation from any other zone. A
Hard Zone disables switching functionality and creates a shared connection between the ports in a zone
topology, splitting the switch into multiple unique FC-AL zones. When Hard Zoning is enabled, all switch
zones must be Hard Zones. A combination of Hard Zones and regular zones on a single switch is not
allowed.
The advantages of Hard Zoning include:
• Each Hard Zone contains 126 available AL_PAs.
• The switch can be configured to contain up to eleven isolated Hard Zones.
The limitations of Hard Zoning include:
• 2 Gb of shared bandwidth over the entire Hard Zone.
• Ports in a Hard Zone cannot use the Stealth Intelligent Change Manager.
• Automatic Trunking and route blocking are not allowed in a Hard Zone.
• Ports in a Hard Zone cannot be set to a string or tree cascade configuration.
• Device AL_PAs on a port in a Hard Zone cannot be displayed.
The Hard Zone setting is available on the One-Step Zoning page. To view the page, click Advanced
Functions > One-Step Zoning.
To set up Hard Zoning:
1. Determine which ports will reside in each Hard Zone and ensure that the ports are in only one
Hard Zone.
2. Under Hard Zone, select the check boxes for the appropriate zones.
3. Click Submit.
Caution: Do not set a Hard Zone for ports in multiple zones or share ports that have the Hard Zone
option set. This will cause errors that do not log an event or display a message.
