Configuration file restoration
8
If a configDownload command is issued on a non-FCR platform, for example, the configuration file
from a Brocade 7500 downloads to a Brocade 7600, any FCR-like parameters may be viewed in the
downloaded data. This is harmless to the switch and can be ignored.
Configuration management supports configDownload with 6.1.x or 6.2.0 configuration files.
Configuration files from a system running Fabric OS v6.2.0 are not backward-compatible, and
cannot be downloaded to a Fabric OS v6.1.0 or earlier system.
Configuration files downloaded from a system running Fabric OS v6.1.0 to a system running v6.2.0,
and to a system running Fabric OS v6.2.0 to a system running v6.3.0, are applied only to the
default switch or chassis areas. All other areas are not affected.
Restrictions
The following limitations apply when restoring a configuration file:
-chassis The number of switches defined in the downloaded config file must match the number
of switches currently defined on the switch.
-fid FID
The FID must be defined in both the downloaded configuration file and the current
system.
-fid FID -sfid FID The –fid FID must be defined on the switch and the –sfid FID must be defined in the
downloaded configuration file.
-all
The number of switches or FIDs defined in the downloaded configuration
file must match the number of switches or FIDs currently defined on the
switch.
The switches must be disabled, if necessary (refer to “Configuration
download without disabling a switch” on page 169 for more information on
non-disruptive configuration downloads). If they are not, the
configDownload command downloads the configuration for as many
switches as possible until a non-disabled switch is encountered. Then it
will stop. Before running this command, verify if any switches need to be
disabled.
In Virtual Fabric-enabled mode, the chassisDisable and chassisEnable
commands are used to disable all logical switches on the affected switch.
This bypasses the need to disable and enable each switch individually
once the configuration download has completed.
Non-Virtual Fabric configuration files downloaded to a Virtual Fabric
system will only have configuration applied to the default switch. If there
are multiple logical switches created in a Virtual Fabric-enabled system,
there could be some issues if there are ports that belong to the default
switch in a Virtual Fabric-disabled system, but are now assigned to logical
switches in a Virtual Fabric-enabled system. Only configurations related to
ports within the default switch will be applied.
