SVS200 LUN Manager and Volume Manager (T1714-96015, October 2007)

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 server

s). 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 th

e 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 lo

gical volumes.

After t

he 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

Manag

er to modify the system conﬁguration. You do not need to reboot the system when changing the

syste

mconﬁguration.

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.
