I could not find out the backup/restore option on AX/CX/VNX either. But at least you can generate the SPCollects log file which contains all the information of a EMC storage.You can refer to the KB "How to run SPCollects from Navisphere Express": [URL]  But anyway replacing a faulted SP should not lose the configuration, what's the status of SPA now? If you log on SPA, could you see the old configuration?  BTW which guide did you refer to replace it? Actually AX150 has its own support site: [URL]  [IMAGE]
I have a failed AX150i storage processor.  It is the processor B.  Processor A is working.  I have a new processor to replace the failed B processor.  I am concerned that I will lose configuration settings when I replace the failed processor B with the new one.  Is there a way to backup and then restore the settings for the disk array?
How do I backup/restore AX150i configuration?
