Back Up the Current Configuration Before Upgrading

Language:

Save the current configuration to a remote site before upgrading the software. Refer to the Sun Network 10GbE Switch 72p Software Configuration Guide for additional information.

If the switch is running the 1.0.1.x release, you can also use the backup and restore feature from Oracle ILOM to save the current Oracle ILOM and SEFOS configurations to a remote server. You can then restore the switch configuration after upgrading the firmware. See Managing SEFOS Configurations.

Note - During the upgrade, if you answer yes to the question Preserve existing configuration (y/n)?, the Oracle ILOM and SEFOS configurations are automatically preserved and there is no need to explicitly restore the configuration. If a syslog server address was configured in Oracle ILOM, the address is not preserved (see CR 7022288), and you must reconfigure the syslog server setting after the upgrade or restore.

Configure the default IP address.
1. Enter Global Configuration mode.
```
SEFOS# configure terminal
```
2. Configure the default IP address and subnet mask as 10.0.0.100 and 255.255.0.0.
```
SEFOS(config)# default ip address 10.0.0.100 subnet-mask 255.255.0.0
```
3. Exit Global Configuration mode.
```
SEFOS(config)# end
```

Configure the restoration file name.

Caution - If you are upgrading the firmware from the 1.0.0.x version, you must complete Step 7 (disabling the incremental-save feature) to save the configuration correctly before upgrading.

Enter Global Configuration mode.
```
SEFOS# configure terminal
```

Configure a configuration restoration file name.

SEFOS(config)# default restore-file myconfig.conf

Exit Global Configuration mode.
```
SEFOS(config)# end
```

Disable the incremental save feature.

SEFOS# configure terminal
SEFOS(config)# incremental-save disable
SEFOS(config)# end

Save the current configuration for restoration.
```
SEFOS(config)# write startup-config
```

Copy the configuration file to a remote location.

SEFOS(config)# copy startup-config tftp://12.0.0.100/switch.conf

Exit and restart the switch.
Note - The switch might currently be low on memory. The restart frees up memory for a more reliable upgrade.
```
SEFOS# exit
-> reset /SP
Are you sure you want to reset /SP (y/n)? y
Performing reset on /SP
```

Login and Save the current configuration again before starting the upgrade.

SEFOS# write startup-config
SEFOS# copy startup-config tftp://12.0.0.100/switch.conf
