(2 and 3 being the old 31 and 32 disk shelves ID's).</P><P>&nbsp;</P><P>Are there any issues in doing this? (this will change the disk id's in dataontap and we wanted to know if data will be affected)</P><P>&nbsp;</P><P>&nbsp;</P> Wed, 04 Jun 2025 23:34:07 GMT https://community.netapp.com/t5/ONTAP-Hardware/SAS-Cabling-from-3-stacks-to-2-stacks/m-p/108456#M6758 PaulIspas 2025-06-04T23:34:07Z https://community.netapp.com/t5/ONTAP-Hardware/SAS-Cabling-from-3-stacks-to-2-stacks/m-p/108457#M6759 <P>There are no issues with changing shelf IDs or moving them to different HBA.
