Information in this section includes cautions, restrictions, special requirements, and information about array characteristics that you might need to consider when configuring or using the storage array.
Requirements for using disks external to the storage array
Data ONTAP supports using the same disks behind the storage arrays that the vendor supports (that is, disks external to the storage array). Data ONTAP assumes that the configuration between the storage array and the external disks behind it is correct.
Hitachi storage array families Data 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.
