21 Configuring FICON display

The recommended policy is to disable the default zone (No Access). Although enabling the default zone (All Access) can be used for FICON environments, prohibiting connection between ports using the Configure Allow/Prohibit Matrix dialog box requires activating at least one zone. Even if you do not want to prohibit connections using the matrix, configuring a single zone containing all ports provides the same benefits as All Access, while providing flexibility to configure “prohibits” or more restrictive zoning in the future. In addition, when moving an ISL in the future, there will not need to modify zoning.

20.Configure zoning using steps under “Configuring zoning” in Chapter 19, “Zoning”.

Be sure to reference the “Zoning and FICON” section of Chapter 19, “Zoning” for more information on FICON environments.

21.Configure the Allow/Prohibit Matrix for the switch using steps under “Configuring an Allow/Prohibit Matrix” on page 702.

22.Configure Call Home by referring to procedures in Chapter 10, “Call Home”.

NOTE

The call home number and the events to trigger a call home depend on your service contract and service provider. Contact your service provider for additional information.

23.Enable bottleneck detection using the following Fabric OS bottlneckmon commands:

•bottleneckmon --cfgcredittools -intport -recover onLrOnly - This command monitors for lost credits on links. This is necessary because occasional errors on links can cause lost credits that can result in IFCCs and poor performance over time.

•bottleneckmon --enable-alert- This command causes AN-1004 RAS log messages to generate whenever congestion occurs and AN-1010 RAS log messages to generate whenever severe congestion occurs. The recommended best practice is to enable alerts now so that you don’t forget when you merging the fabrics.

The bottlneckmon command operates the entire chassis, regardless of the FID where it is executed.

24.Clear error counters (common during switch configuration) by right-clicking the switch in the Connectivity Map or Product List and selecting Performance > Clear Counters.

Configuring FICON display

You can set display settings for FICON display so that the columns of any table that contains end device descriptions to move the following eight columns to be the first columns: FC Address, Serial #, Tag, Device Type, Model, Vendor, Port Type, and WWN.

Configuring an Allow/Prohibit Matrix

The Allow/Prohibit Matrix is a FICON port attribute that can be used to prohibit communication between specific ports. Allow/Prohibit Matrix are not recommended on E_Ports (inter-switch links).
