Do LUN serial numbers need to be unique in ONTAP?
All versions of Clustered ONTAP
- The LUN modify command in ONTAP will let users manually set a serial number.
- These numbers are not required to be unique across ONTAP as long as the LUNs are not mapped. However, they are required to be unique when mapped.
- Mapping two LUNs with the same serial number may cause inconsistency in data service.
