You must meet certain requirements when configuring Hitachi storage arrays to work with ONTAP systems that use array LUNs. These requirements include setting configuration parameters on storage arrays and deploying only supported configurations.
Workaround when LUNs are not visible with Hitachi storage arrays
The storage array parameters specified in the Required parameters for Hitachi storage arrays with systems running ONTAP section should be set and LUNs should be mapped to the host groups before the switch is zoned to connect the ONTAP system that uses array LUNs to a Hitachi storage array.
Requirements for formatting array LUNs
You can perform different types of array LUN formatting. Each type has an impact on the availability of LUNs or the entire storage array.
Requirements for using disks external to the storage array
ONTAP supports using the same disks behind the storage arrays that the vendor supports (that is, disks external to the storage array). When you are deploying storage arrays that use external disks, ONTAP accepts the configuration between the storage array and the external disks.
Hitachi storage array families ONTAP does not support mixing some types of storage in aggregates. To help you determine the array LUNs that can be mixed in an aggregate, the storage arrays from each vendor are grouped into families. When you create aggregates, you cannot mix array LUNs from different vendors and from different storage array families in the same aggregate.
