A consideration when installing Data Protector 10.70 or higher version onto a Linux Operating System (OS) system.

Situation

Since Data Protector version 10.70 (also known as version 2020.05) the use of systemd is supported on the Cell Manager and Clients.

An installation of DP 10.70 or higher version to a Linux Operating System (OS) will first check for the presence of xinetd.
If xinetd is available DP will use it.
If xinetd is not available but systemd is available DP will use systemd.

Systemd is supported on RHEL 8.0 and later versions, and on SLES 15 and later versions.

The installer does not currently check the linux version, so DP will install using systemd to any linux system where xinetd is not available and systemd is available.
This will result in DP being installed in an unsupported configuration.

Advice

With respect to DP 10.70, 10.80, 10.90 and 10.91
Before installing DP ensure xinetd is installed and active on all target Linux systems that are not either RHEL 8.0 and later versions or SLES 15 and later versions.
