Back Up the Current Configuration Before Upgrading

Language:

Save the current NEM configuration to a remote site before upgrading the NEM software. Refer to the Sun Blade 6000 Ethernet Switched NEM 24p 10GbE Software Configuration Guide for additional information.

If the switch is running the 1.1.0.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 Include the SEFOS Configuration in Backups.

Note - During the upgrade, if you answer yes to the question Preserve existing configuration (y/n)?, the Oracle ILOM and SEFOS configurations is 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 7022286), 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 NEM from the 1.0.x.x version, you must complete Step 7 (disabling the incremental-save feature) to save the configuration correctly before upgrading.
1. Enter Global Configuration mode.
```
SEFOS# configure terminal
```
2. Configure a configuration restoration file name for the NEM.
```
SEFOS(config)# default restore-file myconfig.conf
```
3. Exit Global Configuration mode.
```
SEFOS(config)# end
```
4. Disable the incremental save feature.
```
SEFOS# configure terminal
SEFOS(config)# incremental-save disable
SEFOS(config)# end
```

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

Copy the configuration file to a remote location.

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

Exit and restart the NEM.
Note - The NEM 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
Performing reset on /SP
```

Log in 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
