That is pretty much what I thought and also validates the fact that I will be spending my week re-installing and reconfiguring the whole thing.  

On the plus side... it means that I can document the installation and configuration as I go.

ocr location is written in /var/opt/oracle/ocr.loc  

Have a look and see where it is pointing to.  

ASM Disks arent problematic since the disk headers contains the Disk metadata so as long as your ASM instance scan the disk string path it will be able to mount them.

Move storage from EMC to XIOTECH

            Moved from /dev/rdsk/emcpower1g to /dev/rdsk/c1t1d1s1 (for
example) for ocr, for voting disks and for ASM

                        Not sure how this was done, it wasn't documented
and I wasn't involved

Database was happy (for the most part)

Network switch went ka-flooy

New switch... move to new switch... restart server

New mappings take total affect

OCR won't start and I'm pretty sure nothing else will at this point


Yes, I have an SR but I figured I would get outside opinions as well


I have been trying to follow Note 399482.1 - How to recreate OCR/Voting
disk accidentally deleted


I got to the part where you run and it is whining about the emc
device mappings not being there.


This is a test system... it has not had any logs applied in over a week.


>> Question...
In this case, if it were you... would you try to tough it out (which is really cool from a troubleshooting perspective) or opt to rebuild and work forward? Is it worth the effort to try to find all of the places in ASM and OCR and the database where something is going to bite me?
