How to Install and Configure ArecaHwMon for Areca RAID Controllers
This guide shows how to install, configure, and verify ArecaHwMon — a hardware monitoring utility for Areca RAID controllers — on a Linux system. Steps assume a Debian-based distribution (Ubuntu/Debian). Adapt package commands for other distros (yum/dnf/pacman) as needed.
Prerequisites
- Linux server with an Areca RAID controller.
- Root or sudo access.
- Basic familiarity with terminal commands.
- Network access to download packages.
1. Install required packages
- Update package lists:
Code
sudo apt update - Install build and runtime dependencies:
Code
sudo apt install build-essential git libpci-dev libssl-dev pkg-config
(If your distro provides a packaged arecahwmon, prefer that and skip building from source.)
2. Obtain ArecaHwMon
- Option A: Install from distro repository (if available)
Code
sudo apt install arecahwmon - Option B: Build from source
- Clone the repository (example URL — replace with official source if different):
Code
git clone https://github.com/example/arecahwmon.git cd arecahwmon - Build and install:
Code
make sudo make install
- Clone the repository (example URL — replace with official source if different):
3. Load required kernel modules and permissions
- Ensure the system can access PCI devices. If needed, load modules:
Code
sudo modprobe pciutils - Verify the controller is visible:
Code
lspci | grep -i areca - If running as non-root, grant access via udev rule. Create /etc/udev/rules.d/99-arecahwmon.rules with:
Code
SUBSYSTEM==“pci”, ATTRS{vendor}==“0x144a”, ATTRS{device}==“0x”, MODE=“0660”, GROUP=“disk” Replace deviceid from lspci -nn output; reload rules:
Code
sudo udevadm control –reload sudo udevadm trigger
4. Basic configuration
- Default configuration file locations:
- /etc/arecahwmon.conf
- /etc/default/arecahwmon
- Create or edit /etc/arecahwmon.conf with key settings (example):
Code
# /etc/arecahwmon.conf controller = 0# controller index poll_interval = 60 # seconds log_file = /var/log/arecahwmon.log alertemail = [email protected] - Systemd service: create /etc/systemd/system/arecahwmon.service:
Code
[Unit] Description=ArecaHwMon daemon After=network.target[Service] Type=simple ExecStart=/usr/local/bin/arecahwmon -c /etc/arecahwmon.conf Restart=on-failure
[Install] WantedBy=multi-user.target
Then enable and start:
Code
sudo systemctl daemon-reload sudo systemctl enable –now arecahwmon
5. Monitoring and alerts
- Check status and logs:
Code
sudo systemctl status arecahwmon sudo journalctl -u arecahwmon -f tail -n 200 /var/log/arecahwmon.log - Configure email alerts: ensure mail utilities installed (postfix, ssmtp, or msmtp) and test sending:
Code
echo “Test” | mail -s “ArecaHwMon test” [email protected] - For SNMP integration, enable SNMP settings in arecahwmon.conf if supported:
Code
snmp_enabled = true snmp_community = public snmp_traphost = 10.0.0.5
6. Common troubleshooting
- Controller not found: confirm lspci shows device; verify driver availability; check kernel dmesg for errors:
Code
dmesg | grep -i areca - Permission errors: verify udev rules and file permissions.
- Service fails to start: examine journalctl for errors, check binary path in systemd unit.
- Incorrect emails: verify SMTP configuration and logs for mail service.
7. Best practices
- Run monitoring daemon as least-privileged user where possible.
- Keep backups of configuration files.
- Test alerting and simulate drive failures in maintenance windows.
- Update arecahwmon and controller firmware cautiously; test in staging first.
8. Example: Quick verification steps
- Start service:
Code
sudo systemctl start arecahwmon - Verify it detects volumes and status:
Code
sudo arecahwmon –status(Replace with actual CLI options if different.)
- Check log for successful polling every poll_interval.
If you want, I can adapt this to CentOS/RHEL, provide an exact Git URL and makefile commands if you supply the source link, or generate a ready-to-use systemd unit and udev rule with your controller’s device ID.
