Information about low-memory V-Series system upgrade

While upgrading your low-memory V-Series system (a storage system with physical memory of 8 GB or less; for example V3140, V3160, V3210, and V3240) from a previous Data ONTAP release to Data ONTAP 8.2.1, your system might undergo multiple reboots.

Multiple reboots occur if the number of storage devices discovered by the V-Series system exceeds the maximum number of storage devices allowed for that platform. This happens because, in Data ONTAP 8.2.1, memory is allocated dynamically for storage devices as you present the storage devices to your V-Series system.

For information about the number of storage devices allowed for different platforms, see the Hardware Universe at

Note: 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 required license is installed.
