I am new to storage but facing a serious disaster issue of the failure of Dual SAN Controller. Don't know whether this is a right place to ask this question. Anyways the problem is, None of the controllers starting up, Primary controller stuck on Brand Name & Model where as secondary controller stuck on asking for WWN. What are the ways for recovering data from a dead controller??
Just for curiosity Can I use working controller of another SAN of same make and model with this disk enclosures, will it work ?? What are the chances of recovering the data. Already lodged a support request to the vendor but it's taking long to resolve

If you have an identical controller to spare, it might be possible, but you really should identify what is wrong with the current controller. Would be silly to do a ton of work to only find out it's a cable issue. Without more information this question will be tough for us to answer.

Yes we have identical controller. The issue started with disk failure, we replaced it and rebuilding started but after some time controller stopped responding. Other healthy Volumes were working fine even during the rebuild process.

You can ask the question here, but I would recommend to transfer it to Server Fault. They are specialized in server hardware and software.
