Troubleshooting storage system
problems
The storage system troubleshooting described in this chapter covers local storage
systems in which the RAID systems are connected directly to the media platform. If
the media platform is part of an Open SAN, look for additional troubleshooting
information in the Open SAN Instruction Manual.
If your video storage problem is a result of equipment failure, your first indication
might be a message in the NetCentral system. Look through “Checking NetCentral
messages” for the Warning or Alarm message you might see, and the suggested
corrective action.
When you are troubleshooting storage system problems and you have determined that
the problem is hardware related, remember that you are trying isolate the fault to a
field-replaceable unit. Most storage system problems will be confined to:
• the Fibre Channel Disk Interface board
• the Fibre Channel cables
• the RAID storage system
In general, you can verify or rule out hardware problems by using the Profile XP
diagnostics described in Appendix A, Diagnostic Tools. If the diagnostics indicate
that a board is defective, replace that board.
In many cases an improper configuration setting or other change in the system setup
can result in storage system problems. Search through the symptoms in “Correcting
common storage system problems”, then try the corrective action.
