Array LUN name format
Contributors Download PDF of this page
The name assigned to an array LUN has a new format to ensure that the name is unique across a cluster.
The array LUN name consists of two components and looks like the following:
<array_prefix>.<offset>, for example
array_prefixis a unique prefix that ONTAP assigns by default to each storage array.
This field is composed of
<array_name-array_instance> (EMC-1in this case).
array_namecan be denoted by the first three letters of the name of the vendor.
If there is more than one array from the same vendor, the value of
array_instanceproceeds in an ascending order.
The offset is the ascending virtual disk number that ONTAP assigns to each LUN. It is independent of the LUN ID of the host.
You can modify the
<array_prefix> field by using the
storage array modify -name -prefix command.
