Persistent Device Naming

One of the most powerful benefits of storage area networks (SANs) is
scalability; the freedom to quickly add or delete storage components. To
facilitate trouble-free SAN reconfigurations, the user can save a list of
devices currently connected to the host adapter. Later, if certain devices
are powered off, the adapter will ensure the remaining devices appear at
the same mount point. Technically, the LSI Logic host adapter will “lock”
the association of an FC target with an alias name reference. The
LSI Logic host adapter manages the details. When the user marks a
device persistent, mapping information is saved on the LSI Logic host
adapter in a nonvolatile memory device.

The following is an example of how to save devices in the persistent
device table using LSI Logic Fcode:

Step 1.

Select the controller you want to modify, making a selection
from the list as shown in
