- When the network device to replace has failed, step 4 cannot be performed. It is recommended to back up environments regularly in
preparation for failures of network devices.
When performing regular backup of environments, the load of restoration operations after replacement of network devices can be
reduced, by using the latest backup environment.
9.5.2 Regular Maintenance Procedure of Network Devices
This section explains the procedure of regular maintenance (patch application or firmware update) of network devices.
Use the following procedure when performing maintenance operations while continuing operations using the network devices of
redundancy configurations by switching between active and standby.
When there is no description, the following operations are performed by an infrastructure administrator.
1. Announce that regular maintenance operations are being started.
2. Confirm that the network device that is the target of regular maintenance is in standby status, by directly logging in to the network
device.
3. Back up the current network device configuration file from the network device with standby status.
- When the Management Function for Network Device Configuration Files is Used
If the content of the configuration file is up to date, this step is not required.
If the content is not up to date, back up the configuration file using the rcxadm netdevice cfbackup command.
The date and time of backup can be checked using the rcxadm netdevice cflist command.
- When the Management Function for Network Device Configuration Files is not Used
Back up the configuration files from network devices.
For information about the backup method, refer to the network device manuals.
4. Change the target network device in standby status to "maintenance mode".
5. A hardware maintenance person performs the regular maintenance operations for network devices (patch application or firmware
update).
6. Back up the current network device configuration files from the network devices with operational status.
- When the Management Function for Network Device Configuration Files is Used
If the content of the configuration file is up to date, this step is not required.
If the content is not up to date, back up the configuration file using the rcxadm netdevice cfbackup command.
The date and time of backup can be checked using the rcxadm netdevice cflist command.
- When the Management Function for Network Device Configuration Files is not Used
Back up the configuration files from network devices.
For information about the backup method, refer to the network device manuals.
7. Check that there are no differences between the network device configuration files backed up in step 3 and those backed up in step
6.
- When the Management Function for Network Device Configuration Files is Used
Export the configuration file using the rcxadm netdevice cfexport command, and check for any differences. When there is
difference that is a problem, log in to the network device with standby status, and resolve the difference.
- When the Management Function for Network Device Configuration Files is not Used
Export the network device file from the network device and check it for difference. When there is difference that is a problem,
log in to the network device with standby status, and resolve the difference.
For information about how to export, refer to the network device manuals.
For information about login to network devices, refer to the network device manuals.
8. Release the network device from "maintenance mode", after checking that problems with network devices with standby status have
been solved.
