14 LUN Manager for the XP128/XP1024
• Up to 255 hosts can be included in all the host groups for one Fibre Channel port
• Up to 16 hosts can be included in all the host groups for one iSCSI port
Configuring LU paths in a Fibre Channel environment
Before defining LU paths, you must classify server hosts by host storage domains. For example, if Linux and
Windows ® hosts are connected to the disk array, you must create a separate host storage domain for each
host type. When this is done, register the host bus adapters for each host type in the appropriate host
storage domain.
Host storage domains
A host storage domain can contain only hosts that are connected to the same port and cannot contain
hosts that 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
storage domain. You must register the first two Windows hosts in one host storage domain and the
remaining three Windows hosts in another host storage domain.
After server hosts are classified into host storage domains, you must associate host storage domains to
logical volumes. In Figure 1 , the host storage domain hg-lnx is associated with the logical volumes 00:00,
00:01, and 00:02. LU paths are defined between the two hosts in the hg-lnx group and the three logical
volumes.
Figure 1 LU paths configuration in a Fibre Channel environment
LUN Manager lets you define paths between a single server host and multiple LUs. In Figure 1 , both hosts
in the hg-lnx host storage domain can access the three available LUs.
LUN Manager lets you define paths between multiple server hosts and a single LU. In
Figure 1 , the LU
identified as CU-LDEV 00:00 is accessible to the two hosts in the hg-lnx host storage domain.
