To configure multiple-switch zoning, do the following for each switch:
1. Plan which ports should belong in each zone.
2. From the One-Step Zoning page, select the appropriate ports for each zone.
3. Ensure the Zoning Active check box is selected for both switches.
4. After making changes, click
Submit
.
AL_PA Zoning
Another zoning configuration is AL_PA zoning, which enables users to specify that certain devices
only communicate with one another. AL_PA zoning is only accessible through the Command Line
Interface (CLI). Refer to the
InSpeed Storage Switch CLI Reference Guide
for additional
information.
Recovering a Bad Zone Automatically
Bad zone recovery policy automatically recovers traffic if a device has brought down the zone. The
zone state is monitored continuously. If ports are inserted into a zone, but the zone state never
transitions to the Zone Up or Zone Active state after a set period of time (Hold Time), all devices
in the pertinent zone are bypassed and then allowed to reinsert. There is a secondary timeout,
the Bad Zone Recovery Delay Time, that can also be configured. The Bad Zone Recovery Delay
Time causes a delay before ports are allowed to reinsert, which prevents a high "thrashing" level
of port insertions and de-insertions and ensures that some devices can reset. The Bad Zone
Recovery Hold Time and Delay Time threshold settings are available on the Advanced Functions
Switch Thresholds page.
When this policy is enabled with the associated PTBI policy, the device causing a zone to go down
is not allowed back into the zone due to the PTBI policy, which allows the system to return to
normal operation. The combination of the Bad Zone Recovery and PTBI policies has resulted in
significant improvements to SAN availability.
To activate bad zone recovery:
1. Click
Advanced Functions > One-Step Zoning
.
2. Under Bad Zone Recovery, select the check boxes for the appropriate zones.
3. Click
Submit
.
Caution:
Clearing the
Zoning Active
check box will deactivate all zones, which may
degrade system performance or compromise security.
Note:
The Bad Zone Recovery policy is enabled by default. If the Bad Zone Recovery policy is
disabled, use the following instructions to enable this policy for the appropriate zones.
