This section explains the procedure to replace network devices when it becomes necessary due to failure.
Figure 6.2 Image of Network Device Replacement
* Note: L2 switches or switches that comprise the Ethernet Fabric.
It is assumed that you perform replacement while continuing operations using the network devices of redundancy configurations of an active and standby switch configuration.
When there is no description, the operations are performed by an administrator.
In Resource Orchestrator, there are no functions to back up the environment information (definitions, etc.) of network devices.
Therefore, it is recommended to perform backup of the environment information for the network devices at timing such as after completion of the environment configuration or modification of the definition.
For details on backup, refer to the network device manuals.
This section explains the replacement procedure when the device to replace has failed.
Announcement of planned maintenance operations.
Change the target network device to "maintenance mode".
Replace the network devices. (Hardware maintenance person)
Restore configuration of replaced network devices following the maintenance procedure for the network device.
Release the "maintenance mode" of network devices, when problems with network devices after replacement have been solved.
Notification that maintenance operations are complete.
Information
When the replaced network device is a member switch in an Ethernet Fabric configuration (Fujitsu PRIMERGY Converged Fabric switch blade (10 Gbps 18/8+2) or Fujitsu Converged Fabric switch), setting and releasing of maintenance mode is not necessary.
Follow the maintenance procedure for that device.
This section explains the replacement procedure when the network device that is the target of replacement has not failed.
Announcement of planned maintenance operations.
Log in the network device directly to check if the target network device of replacement is in active status or standby status.
When the target network device of replacement is in active status, switch over the device with the standby network device of redundancy configuration, and change the status of target network device for replacement from active status to standby status.
Change the target network device to "maintenance mode".
Back up the current environment (such as definitions) from the network devices that are switched to "maintenance mode".
Replace the network devices. (Hardware maintenance person)
Restore the configuration of the replaced network device using the environment backed up in step 4, following the maintenance procedure for the network device.
Back up the current definitions from the network devices with operational status.
Check that there are no differences in the definitions in the redundancy configurations using environments backed up in step 7 and environment definitions backed up in step 4.
When there is difference that is a problem, log in to the network device directly after replacement, and resolve the difference.
Release the "maintenance mode" of network devices, when problems with network devices after replacement have been solved.
Notification that maintenance operations are complete.
Information
When the replaced network device is a member switch in an Ethernet Fabric configuration (Fujitsu PRIMERGY Converged Fabric switch blade (10 Gbps 18/8+2) or Fujitsu Converged Fabric switch), setting and releasing of maintenance mode is not necessary.
Follow the maintenance procedure for that device.
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.
Announce that regular maintenance operations are being started.
Confirm that the network device that is the target of regular maintenance is in standby status, by directly logging in to the network device.
Back up the current network device configuration file from the network device with standby status.
Back up the configuration files from network devices.
For information about the backup method, refer to the network device manuals.
Change the target network device in standby status to "maintenance mode".
A hardware maintenance person performs the regular maintenance operations for network devices (patch application or firmware update).
Back up the current network device configuration files from the network devices with operational status.
Back up the configuration files from network devices.
For information about the backup method, refer to the network device manuals.
Check that there are no differences between the network device configuration files backed up in step 3 and those backed up in step 6.
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.
Release the network device from "maintenance mode", after checking that problems with network devices with standby status have been solved.
Switch over the network device in active status that is the target of regular maintenance and the network device of the redundancy configuration which is in standby status.
Then change the status of the remaining network device that is the target of regular maintenance from operational status to standby status, and perform steps 3 to 8.
Announce that maintenance operations are complete.
See
For details on how to configure and release the maintenance mode, refer to "20.1 Switchover of Maintenance Mode" in the "User's Guide VE".
Note
Regular maintenance may not be able to be performed using the described procedure depending on the maintenance details for individual network devices. Before performing regular maintenance operations, ensure you check the information provided from the network device vendors regarding the maintenance operations of network devices.
Confirm the following items, using the manuals of network devices, in advance.
The operations for network devices (status check, switchover and backup methods)
Environmental differences which become problems due to redundancy configurations
When performing regular maintenance for multiple network devices of redundancy configurations simultaneously, perform replacement operations in units of the same redundancy configurations.
Information
When the replaced network device is a member switch in an Ethernet Fabric configuration (Fujitsu PRIMERGY Converged Fabric switch blade (10 Gbps 18/8+2) or Fujitsu Converged Fabric switch), setting and releasing of maintenance mode is not necessary.
Follow the maintenance procedure for that device.
This section explains the procedure for adding or modifying destinations for network device connection.
Notify your administrator about the addition or modification of the destination for network device connection. (Network device administrator)
Create network configuration information (XML definition) using the acquired network device information.
Confirm there are no differences besides the link information (under Links tag) regarding the added or modified destinations for connection, by comparing the network configuration information of network devices registered in Resource Orchestrator and the network configuration information created in step 2.
If there is any difference, check with the system administrator that network device configurations have not been modified, and change the network configuration information if necessary.
The network configuration information of network devices registered in Resource Orchestrator can be obtained using the rcxadm netconfig export command.
Modify the network device by setting the confirmed network configuration information as the input information.
Use the rcxadm netconfig import command to modify network devices.
Confirm from the ROR console that the network device information has changed, and the status is normal.
See
For details on how to create network configuration information (XML definition), refer to "8.1 Network Configuration Information" in the "Reference Guide (Command) VE".
For details on the rcxadm netconfig command, refer to "3.2 rcxadm netconfig" in the "Reference Guide (Command) VE".
