2.23 Upgrading RLM Server

Adaptive Computing strongly recommends that your RLM Server is version 12.1.2.

In this topic:

2.23.1 Confirm if an Upgrade is Needed
2.23.2 Upgrade the RLM Server

2.23.1 Confirm if an Upgrade is Needed

Run the following command to determine your current version of RLM Server.

[root]# /opt/rlm/rlm -v

If the version reported is less than 12.1.2, continue with the section to Upgrade the RLM Server later in this topic.

2.23.2 Upgrade the RLM Server

These instructions assume you used /opt/rlm as the install location.

On the RLM Server Host, do the following:

Download the latest RLM build from the Adaptive Computing Moab HPC Suite Download Center.
Stop the RLM service.
```
[root]# systemctl stop rlm.service
```
Archive the existing RLM installation, including the license file(s).
```
[root]# mv /opt/rlm/ /opt/rlm-<archive_version>/
```

Install the new tarball files.

[root]# mkdir -p -m 0744 /opt/rlm
[root]# cd /opt/rlm
[root]# tar -xzvf /<unpack-directory>/ac-rlm-12.1.tar.gz --strip-components=1
[root]# chown -R rlm:rlm /opt/rlm

The --strip-components=1 removes the "ac-rlm-12.1/" from the relative path so that they are extracted into the current directory.

Install the startup scripts.
If you are using a user:group other than rlm:rlm or a location other than /opt/rlm, then edit the following files to reflect those changes after copying them.
```
[root]# cp systemd/rlm.service /etc/systemd/system
```

Restore the license file(s).

[root]# cp /opt/rlm-<archive_version>/*.lic /opt/rlm/

Restart the RLM service.

[root]# systemctl daemon-reload
[root]# systemctl restart rlm.service
