Bind Luns
When you bind a LUN, you select one or more unbound disks and create a new LUN. The Storage
Utility places this new LUN at the bottom of the list and numbers it accordingly. However, with
internal storage, disk numbers are enforced by the chassis slot in which the disk resides. Therefore,
depending on the number and sequence of LUNs created, it is possible that the LUN numbers and
the disk numbers do not match. When you create a new file system, this mismatched numbering
does not hamper functionality. However, to make the internal storage K2 system easy to service,
you should retain the correct numbering sequence. To do this you must unbind all media LUNs and
then bind disks in sequence. On a K2 Media Client, do not unbind LUN0, which is the system drive.

systems.
