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
