Removing DAE from configuration
We recently purchased a used CX500 system. I've wiped domain information and gained access to the system through Navisphere. It appears that 2 DAE's were removed while the system was shut down. There were many LUN's, Storage Groups and Raid Groups configured by the previous owner that were now in fault because of the missing DAE's. My intention is to wipe all of the Raid groups, Storage groups and LUN's and start over. I've managed to Unbind most of the LUN's, then delete the Raid Groups.
Here are my questions.
1. Some LUN's cannot be Unbound. I receive an error message "Being used by a feature of the storage system". How do I Unbind these LUN's
2. How do I get the system to stop looking for the missing DAE's?
3. There is also a list of hosts in the hosts tab from the previous owner that I'd like to remove but don't see a delete option.
That's a lot of questions but any assistance on any of them would be appreciated.
1) see if this helps

2) restarting Navisphere Management service does not help ? (http://spa/setup)
3) Are these hosts listed in Connectivity Status ? Get into engineering mode (Ctrl+Shift+F12 ..contact EMC for password - edit by Glen) and see if you can purge them.

Thanks dynamox.
1) Unbinding the remaining LUN's is still not happening. Once in engineering mode, I do see a "~physical" storage group which all of the locked LUNs belong to. Any effort to remove the LUN's from the storage group produces a new error "Results from call to remove LUN(s) from storage group:SP A: Special storage group cannot be modified., SP B: Special storage group cannot be modified.

All of the LUN's show up in the "Unowned LUNs" group. Thanks for the help and I'll keep searching.
2) I've restarted the Management service, the Storage Processors etc. The missing DAE's finally went away in Navisphere. I now think that maybe one DAE is mis-identified. Bus 1 Enclosure 1 shows a number of drives missing and failed but in reality it's full of drives and looks to be functioning normally.
3) I was able to clear the hosts from the Connectivity Status dialog. They are now gone.

OK, tried the cli that you recommended. Results for all of LUN's that throw the "Being used by a feature of the storage system" are;
Listed Driver: K10SnapCopyAdmin
I tried the command "-Scope 0 setfeature -off -feature sancopy -lun 1"
Didn't produce any errors at the command line but when I run the first command again it still shows Listed Driver: K10SnapCopyAdmin
As for the Bus 1 Enclosure 1 looking odd. The cables were not plugged in correctly. Plugged them in to the correct ports on the DAE and that enclosure looks fine now.

when I run that I get;
usage: setfeature -on|-off [-feature rm|sancopy -lun lun_number|-lunuid uid]
Specified feature not supported

It's an ebay special. Maybe I should run the serials by support on the off chance it's still covered.

worth a shot. DId you get any enablers when you bought it ? I was thinking if you could remove sancopy/snapview enablers, bounce both SPs and then re-install them.
