Re: Celerra NS-120 / Storage processor ready to restore
Lun 0 is the control lun for the nas side, you should able to trespassed back to the default sp with little performance(pending on IO) or no impact at all.
It should be transparent to the host like dynamox mentioned above.
If I may recommend, (safest way)
- I would replace your disk first, using USM which you can probably downlaod from support.emc.com
- Wait till it fully transitioned, once complete. Make sure there are no other hw failure
- Trespass the lun using nas_storage -f id=1 (wait a few minute untile prompt comes back saying "done")
- then run nas_checkup to ensure the entire array is clean.
