Issue/Introduction

The DX NetOps Spectrum installation fails on Linux environments, frequently resulting in failed service creation (such as sradmin) during silent mode installation.

/sw/SPECTRUM/SRAdmin/sradmin.exe -version

SPECTRUM version available, Build/Version: 25.4.9.000

systemctl start sradmin

Failed to start sradmin.service: Unit sradmin.service not found

ls -la /etc/systemd/system/sradmin.service

ls: cannot access '/etc/systemd/system/sradmin.service': No such file or directory

Environment

NetOps Spectrum 25.x; Linux (RHEL 8.9 and higher).

Cause

• Silent Mode Service Failure: The sradmin service fails to create post-installation when the installer environment is improperly prepared or when files are corrupted.
• File Corruption: Extraction of the installation archive (.tar.gz) on a Windows machine before transferring to the Linux host causes file corruption, which specifically affects the success of silent mode scripts.

Resolution

1. Ensure File Integrity: If the installation archive was transferred from a Windows machine, the files are likely corrupted, leading to silent mode script failures.

   • Copy the original NetOps-Spectrum-[Version]-Linux-RELEASE.tar.gz file directly to the Linux target machine.
   • Extract the archive directly on the Linux host: tar xvzf NetOps-Spectrum-[Version]-Linux-RELEASE.tar.gz -C /opt/installer/Spectrum[Version]
   • Run the installation again from the extracted directory.

2. Prepare Environment for Silent Mode: Ensure the environment is correctly configured for silent installation execution:

   • Execute the silent installation using the provided hostargs.txt configuration file: ./srainstall.bin -i silent
