Storage Management Software
Software for configuring and managing storage devices such as RAIDs and tape libraries
from Windows NT typically requires the capability of issuing SCSI commands to devices
representing the hardware in question. When SAN Manager LM is installed on a SAN, these
commands cannot be sent to such a device unless the device is assigned to the host on
which the software is run. The same LUN often represents a unit of storage as well as a
management command target, so it may be necessary to assign a storage LUN to the
management host (perhaps temporarily) even though the storage is not needed on that
host.
CLARiiON’s Navisphere is an example of such management software. As an alternative to
assigning a LUN from every CLARiiON RAID to the Navisphere Manager host, you can
assign the LUNs wherever the storage is actually needed and run the Navisphere Agent on
the same hosts. The Navisphere Manager can manage the RAIDs via these agents.
