Hello Duhhas,  Thanks for contacting EMC Community.  Since your TDEVs are not bound to a pool so you can delete them as they are not more than pointers in the cache. No data is associated with them since they are not bound to any pool in your Symmetrix.  Hope this helps Mohammed Salem
I'm in the process of cleaning up things in an aquired vmax env.  I have a bunch of devices that I believe I can remove and wanted to get an understanding of anything else I should consider before assuming devices are not used:  [IMAGE] not tied to any pool, 0 paths defined for each, seems like a no brainer, just trying to understand if i'm missing something
lots of devices, no place to go
