don't need to do anything, slide old SP out ..put new SP in. It will boot and copy all configuration from the other SP, including WWNs. You may need to trespass LUNs back to default owners.
This is an old CX300(out of warranty, end of Life, but pretty useful for lab) with flare 19 on it.  I need to replace the storage processor on it.   I've found some different sources, got some pricing, then looked for a replacement procedure.  I did find a procedure detailing the physical replacement process, however it didn't cover any software configuration. [URL]  So my question is, do I need to go through and reconfigure the SP?  Do I need to initiate and software installation?  Or does it just pull everything from the system disks and just works like magic?  It's on all attached via Fiber so I'll probably have to rezone the new gbic's since they'll have different WWN's, but is that all?  I apologize if there is a document detailing this process and I just completely missed it.   Never done this before so just thought I'd ping the forums.
