Configuring LU paths
When provisioning your storage system, and after configuring ports, hosts, and host groups, you
must configure fibre channel LU paths. LUN Manager is required for these tasks. You can also
modify the LU paths configuration when the system is in operation.
Defining LU paths
In a fibre channel environment, you must define LU paths and associate host groups with logical
volumes. For example, if you associate a host group consisting of three hosts with logical volumes,
LU paths are defined between the three hosts and the logical volumes.
When you use a logical volume larger than 2 TB, whether the host can access that logical volume
depends on the operating system of the host. The following operating systems support a logical
volume that is larger than 2 TB.
•
AIX 5.2 TL08 or later
•
AIX 5.3 TL04 or later
•
Windows Server 2003 SP1 or later
•
Red Hat Enterprise Linux AS 4 Update 1 or later
If you use an operating system other than these, make sure that a logical volume is not larger than
2 TB. For information about the maximum logical volume capacity supported by your operating
system, contact the vendor of your operating system.
