Removing an AL_PA blocking member from a group
(root/config/zone/delblk)
This command deletes an AL_PA member from an AL_PA blocking group.
To remove an AL_PA member from a blocking group:
From the Zoning configuration menu (root/config/zone), type
delblk <group
number> <AL_PA member>
and press E
NTER
.
Note: Changes to blocking configurations require that zoning be active. See “Activating
zoning (root/config/zone/act)” on page 43.
For example: There are two HBAs in blocking group 1 and you want to remove HBA2
from the blocking group.
• HBA1 (Port 1, AL_PA 02).
• HBA2 (Port 2, AL_PA 04).
To remove HBA2 from blocking group 1:
1. Type
delblk 1 04
and press E
NTER
.
This removes HBA2 from blocking group 1.
2. Ensure zoning is activated and reset the switch for the changes to become active on
the switch.
Displaying AL_PA blocking groups (root/config/zone/showblks)
This command displays the route blocking configuration for all route blocking groups.
To view the AL_PA blocking groups:
From the Zoning configuration menu (root/config/zone), type
showblks
and press
E
NTER
.
Configuring the Hard Zone policy (root/config/zone/hz)
This command displays and configures the hard zone policy for a specific zone.
Note: Zone 0 is reserved and cannot be configured for 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.
Note: 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.
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.
