Overview

You may need to reset an RTR node; for example, after running a Health Check and finding it has been up and running for a long time (e.g., more than a year), which is not recommended. This article details the steps to reboot an RTR node.

 

Prerequisites

• Access to the nodes through SSH.
• In case you don't have SSH access, please follow instead Rebooting a Lithium Node via iLO3

Process

 

1. Check System Health on affected nodes

a. syswatch

# su – 
# syswatch 

Ensure there are no health issues noticed.

b. Ilo check

• Check from ILO if all hardware components are fine
• Check for firmware version and compare to other nodes

 

2. Check network interfaces to compare with other servers

# ifconfig –a
# ethtool <interface name>
# ethtool -i <interface name>
# ethtool -t <interface name>
# ethtool -S <interface name>

• If any differences in driver versions etc are noticed, check step 7.
• If no differences between this server and other servers, then proceed to the next step

 

3. Stop textpass /rtr processes

# su - textpass
# su – textpass -c "tp_stop"
# su – textpass -c "tp_status"

 

4. Reboot the server

# su - root
# shutdown –r now

Wait for the reboot to complete and the server restarts. Then, proceed to the next step.

 

5. Start textpass process

# tp_start --textpass
# tp_status

The next actions depend on the status of starting the textpass process. If everything is OK, go to the next step.

 

6. Start All processes

# tp_start
# tp_status

Ensure All processes are started and operating normally

 

7. Network Interfaces

If any issues/differences are found in the network interfaces of affected servers when compared to the working server, the following actions could be attempted depending on the outcome

• Update Drivers 
• Remove Ethernet configuration
• Re-Configure Network interfaces

 

Timelines and Impact

Expected Time	Expected Impact
30 minutes per server (in total)	No traffic on this server. However, other servers in the network should be able to cover all traffic
