Requirements for cabling HA pair

If you want to install and cable a new standard or mirrored HA pair, you must have the correct tools and equipment and you must connect the controllers to the disk shelves., If it is a dual-chassis HA pair, you must also cable the HA interconnect between the nodes. HA pairs can be installed in either NetApp system cabinets or in equipment racks.

The term V-Series system refers to the storage systems released prior to Data ONTAP 8.2.1 that can use array LUNs. The FAS systems released in Data ONTAP 8.2.1 and later can use array LUNs if the proper license is installed.

The specific cabling procedure you use depends on whether you have a standard or mirrored HA pair.

NetApp Documentation: Disk Shelves

Multipath HA connection is required on all HA pairs except for some FAS22xx, FAS25xx, and FAS2600 series system configurations, which use single-path HA and lack the redundant standby connections.
