Data Domain: Hardware Healthcheck

# support healthcheck hardware 

The support healthcheck hardware command is designed to initiate a comprehensive hardware health check on Data Domain systems. The command conducts thorough diagnostics on various hardware components, including storage disks, power supply units, fans, SAS controllers, QAT, NVRAM, DIMMs, I/O cards, and CPUs. The output provides the status of each component. If any component fails the check, the output includes detailed information and recommended remediation steps.
