The problem with this is: when we dump something on to the RAID, its fine, but not when we want to retrieve the data.
I would recommend first contacting the provider or systems integrator from where you obtained the system. Ask them to identify that all of the components including hardware, network and software are configured properly and at the applicable revision levels. Also, make sure that all components are in a supported configuration across all of the components. You may run into some finger pointing, where you get a response that nothing is wrong with the network, or nothing is wrong with the server or nothing is wrong with the software.
If your provider is not able to provide any assistance, contact the manufacturers and use their support Web sites for tips on what you should do to troubleshoot your issues.
