2 About LUN Manager Operations
The HP storage system can be connected to open-system server hosts of different platforms (for example,
UNIX servers and PC servers). To configure a system that includes open-system hosts and a storage
system, you must use LUN Manager to configure logical volumes and ports.
Oneofthe important tasks with logicalvolumeconfiguration is to define I/O paths from hosts to logical
volumes. If thepaths aredefined, the hosts can send commands and data to the logical volumes and
receive data from the logical volumes.
After the system begins operating, you might need to modify the system configuration. For example, if
hosts or disks are added, you will need to add I/O paths. Even when the system is operating, you
can modify the system configuration with LUN Manager. You do not need to reboot the system when
changing the system configuration.
Note
:
• Throughout this manual, logical volumes are sometimes referred to as logical devices (or LDEVs).
• LUN Manager lets you make various settings with logical volumes (LUs). The settings include the
LU path settings. When you configure a system, you must define LU paths to let the hosts transfer
data to and from storage.
• It is necessary to change the mode of the HP StorageWorks XP Remote Web Console main
window to the Modify mode to do various settings with LUN Manager. When the background
color of
the icon on the right of the window is light yellow (
), the window is in the Modify
mode. W
hen the background color is gray (
), it is in the View mode. If you click the ( )icon
when the Unlocked icon (
)is displayed,the icon changesto( ) and the mode is changed
to the Modify mode. For details on how to change to the Modify mode, see HP StorageWorks
XP24000 Remote Web Console User's Guide.
Caution:
When you define the LU paths, you must not use HP StorageWorks XP RAID Manager and
Remote Web Console at the same time.
“Overview of Fiber Channel Operations” on page 15 explains LU path settings in a Fibre Channel
environment.

After
open-system hosts and the storage system are physically connected by cables, hubs, etc., you must
use L
UN Manager to establish I/O paths between the hosts and the logical volumes. This defines which
host is able to access which logical volume. Logical volumes that can be accessed by open-system
hosts are referred to as logical units (LUs). The paths between the open-system hosts and the LUs are
referred to as LU paths.
Before defining LU paths, you must classify server hosts by host groups. For example, if Linux hosts and
Windows hosts are connected to the storage system, you must create one host group for the Linux hosts
and another host group for the Windows hosts. Then, you must register the host bus adapters of the
Linux hosts in the Linux host group. You must also register the host bus adapters of the Windows hosts
in
the Windows host group.
Ahostgroup canonlycontain hoststhatare connected to thesameport, andcannotcontain hoststhat
are connected to different ports. For example, if two Windows hosts are connected to port 1A and three
Windows hosts are connected to port 1B, you cannot register all five Windows hosts in one host group.
You must register the first two Windows hosts in one host group and then register the remaining three
W
indows hosts in another host group.
