Configuration Restoration In A Ficon Environment; Traffic Isolation Zoning - Brocade Communications Systems StoreFabric SN6500B Administrator's Manual

Configuration restoration in a FICON environment

If the switch is operating in a FICON CUP environment, and the ASM (Active=Saved) bit is set on,
then the switch ignores the IPL file downloaded when you restore a configuration.
describes this behavior in more detail.

If FMS mode is enabled in a configuration file, but is disabled on the switch, the configDownload
command fails and displays an error message. This prevents undesirable conditions that could
result from enabling fmsmode on a switch that does not require it.

Traffic Isolation Zoning

Traffic Isolation (TI) Zoning allows data paths to be specified. In a FICON fabric, you need Fabric OS
v6.2.0 or later. TI Zoning has the following benefits:
•
•
•
Creating logical switches is preferred over creating TI Zones for FICON emulation configurations.
Logical switches can be created easily and they naturally separate disk and tape traffic to different
tunnels and network bandwidth.
For more information on Traffic Isolation Zoning, refer to the Fabric OS Administrator's Guide.
NOTE
Session-based zoning enforcement is not recommended on a FICON switch. For more information
on session-based zoning enforcement, refer to the Fabric OS Administrator's Guide.

Configuration restoration in a FICON environment

Description
All the files saved in the file access facility are uploaded to the
management workstation. A section in the uploaded configuration file
labeled FICON_CUP is in an encoded format.
Files saved on the switch that are also present in the FICON_CUP
section of the configuration file are overwritten.
Files in the FICON section of the configuration file that are not
currently present on the switch are saved.
The IPL file is not replaced, because Active=Saved mode is on.
Files saved on the switch that are also present in the FICON_CUP
section of the configuration file are overwritten.
Files in the FICON section of the configuration file that are not
currently present on the switch are saved.
The IPL file is replaced, because Active=Saved mode is off. A warning
message is displayed in the syslog to warn that the IPL file is not being
overwritten.
