After server hosts are classiﬁed into host groups, you must associate host groups to logical volumes.

In Figure 1 on page 16, the host group hg-lnx is associated with three logical volumes (00:00:00,

00:00:01, and 00:00:02). LU paths are deﬁned between the two hosts in the hg-lnx group and the

three logical volumes.

LUN Ma

nager lets you deﬁne paths between a single server host and multiple LUs. In Figure 1 on page 16,

each o

f the two hosts in the host group hg-lnx is able to access the three LUs.

LUN Ma

nager lets you deﬁne paths between multiple server hosts and a single LU. In Figure 1 on page 16,

the L

Uidentiﬁed by the LDKC-CU-LDEV number 00:00:00 is accessible from the two hosts that belong to

the hg-lnx host group.

In Figure 1 on page 16, the LUs associated with the hg-lnx host group are addressed by numbers 0000 to

0002. The address number of an LU is referred to as LUN (logical unit number). When HP StorageWorks

XP Continuous Access Software and other program products manipulate LUs, the programs use LUNs

to specify the LUs to be manipulated.

You

can add, change, and delete LU paths when the system is in operation. For example, if new disks or

ser

ver hosts are added to your storage system, you can add new LU paths. If an existing server host is to

replaced, you delete the LU paths that correspond to the host before replacing the host. You do not

need to restart the system when you add, change, or delete LU paths with LUN Manager.
