HP B-series Fabric OS 7.1.0c Release Notes (5697-2892, October 2013 - includes all 7.1.0x versions)

CommentsArea
When setting insistent domain ID on a switch using the FICON Configuration Wizard, the
switch is always taken offline and insistent domain ID set, even if insistent domain ID is already
set.
Manageability
The PORT BANDWIDTH in the FICON Director Activity Report from RMF may not be accurate.Managebility
FPGA version 0x1C on the HP DC SAN Director Multiprotocol Extension Blade is not supported
with Fabric OS 7.0.0c, Fabric Os 7.0.0d, and Fabric OS 7.1.0c.. The FPGA version can be
checked by issuing the bladevershow command.
Serviceability
The SIOCA tool run from HMC on System z performs a similar function and therefore may
not give reliable results.
Serviceability
Under certain circumstances, enabling multiple Traffic Isolation Zones with failover disabled
may cause frames to be dropped due to the timing when paths are re-routed while the zones
Traffic Isolation Zones
are being implemented. To avoid this, all Traffic Isolation Zones should be enabled with
failover enabled first, so that all desired routes are established.
Contact HP technical support before attempting to configure and enable this feature.Traffic Isolation Zones
Contact HP technical support before attempting to enable Virtual Fabrics or use the XISL (Base
Switch ISL) capability.
Virtual Fabrics
If a port is assigned a port address of 0xFE in an Open System logical switch, an RSCN is
sent by Fabric OS on behalf of port address 0xFE during CP failover or firmware download.
This may result in an IFCC for any FCP channel running traffic to port address 0xFE.

Interoperability
When cascaded to other switches, referred to as a fabric, all switches in the fabric must be at
Fabric OS 7.0.0c or 7.0.0d before upgrading to Fabric OS 7.1.0c. Interoperability between
switches at Fabric OS 6.4.2a, 7.0.0c, 7.0.0d, and 7.1.0c is supported. However, the recommended
best practice is to have all switches in the same fabric at the same code level.
The next section indicates supported intra-fabric interoperability between hardware platforms,
supported management software levels, and recommended firmware versions.
FICON hardware/firmware/software interoperability with Fabric OS 7.1.0c
Interoperability is supported with Fabric OS 7.1.0c between the following platforms:
• HP DC SAN Backbone Director Switch
• HP DC04 SAN Director Switch
• HP SN8000B 8-Slot SAN Backbone Director Switch
• HP SN8000B 4-Slot SAN Director Switch
• HP SN6000B 16Gb FC Switch
• HP 8/80 48-ports Enabled SAN Switch
• HP 1606 SAN Extension Switch
