Goal

To save and restore a switch configuration when upgrading or replacing a defective Oracle 10Gb switch

Solution

1) Before upgrading or replacing a configured switch, check if a backup configuration has been stored on a safe place.

2) If there is no backup and the switch is not down hard, inspect the switch configuration and take a backup as described in the Product Notes.
By default, only the Oracle ILOM configuration is backed up when the backup feature is used. Complete the following tasks to include the SEFOS configuration in this backup.

Include the SEFOS Configuration in Backups

Before backing up your SEFOS configuration using the Oracle ILOM backup feature, complete the following tasks:

■ Save and inspect the current switch configuration. For example

SEFOS# write startup-config
SEFOS# sh run

Building configuration...
...

■ In ILOM, set a passphrase and dump the backup. This passphrase is to be used during the restoration phase (see below).

-> cd /SP/config
-> set passphrase=abc123
-> set dump_uri=ftp://username:password@192.168.1.100/tmp/mySwitchConfig.bak
Dump successful.

Note: It is critical to set the passphrase, otherwise the there will not be a complete back up.
Note: For FTP, if the specified user name is a normal user at the FTP server end, even if the specified user password is correct, there can be possible permission issues with the PUT operation. In such scenario, dump may not succeed, and using the root-user at the FTP server end is recommended here.
Note: Besides FTP, SFTP is also a good alternative. The dump_uri format for SFTP is identical to that for FTP but just specify the protocol as sftp://...

Verify the Backup

■ check backup status on SEFOS

SEFOS# sh system info

</SP_config>

If the SP configuration is backed up with a passphrase, then SEFOS configuration is also included but in encrypted format. Should there be a need to back up individual SEFOS files, then one can also do something like this:

-> ls /SP/config/sefos/
-> set /SP/config/sefos dump_uri=ftp://user_name:user_password@192.168.1.100/var/tmp/switch.conf

Restore the Configuration

■ Configure the network settings on the Oracle ILOM network management interface to communicate with the backup server.

-> cd /SP/network
...

■ Set the passphrase to the same value that was used for backup.

-> cd /SP/config
-> set passphrase=abc123

■ Restore the configuration from the server.

-> set load_uri=ftp://username:password@192.168.1.100/tmp/mySwitchConfig.bak
Load successful.

■ Check config again to ensure it is restored.
