DAE bus/ enclosure address information on VNX
Hi,
We are relocating a VNX5300. As it turns out, we disconnected the SAS-cables from their DAEs and didn't remember to document how the daisy chain was formed. Is there any way to find out the correct order, do the DAEs or the array itself remember the bus / enclosure address of each DAE?
Any help would be appreciated.

A VNX5300 definitely wont remember or tolerate cabling being changed.
If you have an old SP collect it should show it in there

I would suggest to contact your EMC or partner support to check if they have a SPcollect from your system on record
If you have Unisphere Service Manager installed on any computer you used for ie FLARE upgrade, check the C:\EMC\repository\ folder on that machine. You should have arrayconfig data there or SPcollects.
You can build it back according to the specs. Depends if you can track any changes from the last time.
Last resort, you probably can boot up only the DPE and download the latest SPcollects. Check with EMC support and open SR for that I guess.

Is there anything that could be done in this case? If we try the cabling, will it result to data loss (our storage guy is pretty sure he remembers how it was) but if we get it wrong on the first try, what will happen?
