HP StorageWorks XP10000 Disk Array - Manual (Page 18)

Figure 1 Array integrating Fibre Channel, iSCSI, and NAS environments
You can connect the array to open-system server hosts on different platforms (for example, UNIX and
PC servers). To configure a system that includes open-system hosts and an array, you must use LUN
Manager to configure logical volumes and ports.
One of the important tasks with logical volume configuration is to define I/O paths from hosts to logical
volumes. If paths are defined, hosts can send commands and data to logical volumes and receive data
from logical volumes.
After the system begins operating, you might need to modify the system configuration. For example, if
you add hosts or disks, you must add I/O paths. Even when the system is operating, you can use LUN
Manager to modify the system configuration. You do not need to reboot the system when changing the
system configuration.
NOTE:
Throughout this user guide, logical volumes are sometimes referred to as logical devices (LDEVs).
Configuring LU paths
Use LUN Manager to make various settings for logical volumes (LUs), including LU path settings. When
you configure a system, you must define LU paths to let hosts transfer data to and from storage.
CAUTION:
When defining LU paths, you must not use RAID Manager XP and XP Remote Web Console at the
same time.
