Tips for DSA Troubleshooting
Observe the following tips when troubleshooting DSA
products:
• Avoid formatting new HDA units.
• Note that EDC errors are not drive problems.
• Note that forced errors are not necessarily HDA
problems.
• Avoid running standalone diagnostics unless drive
or system error logs are unavailable and all other
troubleshooting techniques have failed.
• Ensure that equipment is thermally stabilized before
attempting to power up.
• Use proper ESD grounding methods. Equipment is
highly susceptible to static damage.
• Adhere to the service delivery strategy as outlined in
specific component service manuals.
