Fabric OS 6.2 administrator guide 171
CAUTION: Do not download a configuration file from one switch to another switch that is a different
model or firmware version, because it can cause the switch to fail. If you need to reset affected switches,
enter the configDefault command.
IMPORTANT: Verify that all domain IDs are unique prior to performing the configDownload because
the switches will segment if they all have the same domain ID.
If you download an existing configuration file to a switch that has a different interoperable mode setting,
the configDownload command will fail. You must first change the switch’s interoperable mode to equal
that of the configuration file, reboot the switch, and then re-download the configuration file.
Downloading a configuration file from one switch to another same model switch
1. Configure one switch.
2. Use the configUpload command to save the configuration information. See ”Configuration file
backup” on page 165 for more information.
3. Run configDefault on each of the target switches, and then use the configDownload command
to download the configuration file to each of the target switches. See ”Configuration file restoration” on
page 166 for more information.
Security considerations
Security parameters and the switch's identity cannot be changed by the configDownload command.
Parameters such as the switch name and IP address (lines in the configuration file that begin with boot)
are ignored. Security parameters (lines in the configuration file that begin with sec), such as secure mode
setting and version stamp, are ignored.
For more detailed information on security, see Chapter 3, ”Configuring standard security features” on
page 99.
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, the
switch ignores the IPL file downloaded when you restore a configuration. Table 47 describes this behavior
in more detail.
Table 47 Backup and restore in a FICON CUP environment
ASM bit Command Description
on or off configUpload 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.
on configDownload 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 on. A
warning message is displayed in the syslog to warn that the IPL
file is not being overwritten.
off configDownload 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 off.
