unavailable.
Use either SFOS or ACLs to establish an SCC policy for Fabric Binding. SFOS and ACLs are mutually
exclusive—you must use one or the other to establish Fabric Binding for FICON.
15
• Use SFOS for firmware versions earlier than 5.2.0a; it requires an additional license.
• Use ACLs with firmware 5.2.0a or later.
Only 16-port or 32-port blades can be installed in slot 10 of a 4/256 SAN Director.16
The MPR Blade is supported in the DC SAN Backbone Director, DC04 SAN Director, and 4/256
SAN Director only. A maximum of eight MPR Blades per DC SAN Backbone Director, four MPR blades
per DC04 SAN Director, and two MPR Blades per 4/256 SAN Director is supported.
17
When configuring TI zones, you can enable or disable failover. For more information about using TI
zones in a FICON environment, see “TI zones with the Advanced FICON Accelerator”, and the HP
StorageWorks Fabric OS 6.x Administrator Guide.
18
When configuring Port Fencing, HP recommends that you use the default parameters in order to
prevent normal fabric events from resulting in disabled ports.
19
Multiple 10 Gb/s ISLs can load share between cascaded FICON directors, but cannot load balance
over multiple 10 Gb/s ISLs.
20
Multiple FCIP links can be configured between cascaded FICON directors to provide load sharing
and redundancy. To load balance over multiple FCIP links, you must configure FCIP tunnels. FCIP
tunnels are supported on the 1606 Extension SAN switch and MP Extension Blade only.
FCIP tunnels (virtual E_Ports) pass traffic between the SAN extension devices.
21
• The 1606 Extension SAN Switch supports up to 8 FCIP tunnels.
• The DC Dir Switch MP Extension Blade supports up to 20 FCIP tunnels.
FCIP is supported between pairs of 1606 Extension SAN Switches and DC Dir Switch MP Extension
Blades, or between a 1606 Extension SAN Switch and a DC Dir Switch MP Extension Blade.
22
FCIP is not supported in between the 1606 Extension SAN Switch or DC Dir Switch MP Extension
Blade and the MP Router, 400 MP Router, or MP Router Blade.
The DC Dir Switch MP Extension Blade is supported in the SN8000B 8-Slot, SN8000B 4-Slot SAN
Directors, DC SAN Backbone Director, and DC04 SAN Director only.
23
A maximum of eight MP Extension Blades per SN8000B 8-Slot SAN Director and DC SAN Backbone
Director and four per SN8000B 4-Slot SAN Director and DC04 SAN Director is supported.
When using the Advanced FICON Accelerator:24
• Before configuring the accelerator, you must define the FCIP interfaces and tunnels to be used and
persistently disable the ports. The ports can be enabled after the accelerator is configured.
• If there are multiple FCIP ISLs between switches, TI zones must be configured with failover disabled
so that each device uses only one FCIP ISL. For more information on configuring TI zones, see HP
StorageWorks Fabric OS 6.x Administrator Guide or HP StorageWorks Fabric OS 7.x Administrator
Guide.
• FICON tape and virtual tape devices must run in single path mode. The accelerator does not
support multiple paths varied online to the same tape device.
XISLs are supported in the same physical director as FICON, but they do not support FICON traffic
and cannot be configured for use on a FICON virtual switch.
25
8 Gb/s switches and ARB(FF)/ARB(FF) mode setting—All 8 Gb/s FICON ports in a FICON
director/switch running FOS 6.2.0e and later must be set to mode 1 using the portcfgfillword
26
command. For more information, see HP B-series Fabric OS 6.2.0e Release Notes (or the latest version
supporting FICON).
NOTE: Not all topologies can support the maximum port or director count.
