Displaying the zone state (root/config/zone/zstate)
This command displays the current zone state for a specified zone or all zones. The
zone state may be "up" (operational) or "down" (non-operational).
To view the zone state for all zones:
From the Zoning Configuration menu (root/config/zone), type
zstate
and press E
NTER
.
To view the zone state for a specific zone:
From the Zoning configuration menu (root/config/zone), type
zstate <zone number>
and press E
NTER
.
Clearing zones (root/config/zone/zclr)
This command clears out the port members from a specified zone. If the specified zone
is 0, it will clear all of the zones.
To clear a specific zone:
From the Zoning Configuration menu (root/config/zone), type
zclr <zone number>
and press E
NTER
.
To clear all zones:
From the Zoning configuration menu (root/config/zone), type
zclr 0
and press E
NTER
.
Adding an AL_PA blocking member to a group
(root/config/zone/addblk)
This command adds an AL_PA member to an AL_PA blocking group to set up a route
blocking zone and prevent devices (using AL_PAs) from accessing one another.
AL_PA zoning fully ensures that devices will not access each other. It does this by
blocking a group of devices from sending OPN signals to each other but allows the
devices to send OPNs outside of the group. This group of devices is called a "route block
zone", not to be confused with the port zones discussed earlier. Port zoning without
route blocking makes the separated ports unaware of each other, but this does not
prevent all OPN signals from getting through. Therefore, it is recommended that you
create a route block zone and include any AL_PAs that should not access each other.
Note: Zoning must be activated for route blocking to work properly.
