Chapter
24. Multiple file server I/O processors and Multiple AS/400s
-
-
The information in this chapter applies to Integration for NetWare.
Your LAN may have more than one Integrated PC Server or more than
one AS/400, which may be connected to more than one LAN. The following
sections discuss some of these combinations and their effects.
Depending on the model of AS/400, you can have multiple file server I/O
processors on one AS/400. Each file server I/O processor requires a separate
license for NetWare. Each file server I/O processor also requires a network
server description, IPX description, IPX circuit, line descriptions, and
storage spaces. Only the storage spaces can be shared between file server
I/O processors and only if they are in read-only mode. Because each file
server I/O processor requires its own NWSD, each file server I/O processor
is viewed as a separate server with its own disk space.
Figure 24-1. Multiple file server I/O processors
on an AS/400
If the file server I/O processors on your AS/400 must communicate with
one another, you can connect all the file server I/O processors to the
same LAN. If, however, you need to connect the file server I/O processors
to different LANs, you have two options.
-
You can use native IPX support on AS/400 to share data.
With native IPX support, a requester on a LAN can access another
file server I/O processor in the same AS/400 but on another independent
LAN.
-
You can use a LAN bridge to share data.
With
a LAN bridge, a requester can access volumes belonging to another file
server I/O processor on the same AS/400.
Multiple file server I/O processors on the same AS/400 can share volumes
and thus share data. To do this, the storage spaces on AS/400 must
be linked using *READ access, which means the data is in READ ONLY mode.
Online documentation that must be shared between many users but does not
need write access is a good example of using shared volume support.
To change how a volume is accessed, you must vary off the network server
description, unlink the storage space, link it with the new access value
and vary on the network server description.
Installation
of Multiple file server I/O processors
When you are installing multiple file server I/O processors on the same
AS/400, you only need to do the installation once unless you are installing
more than one language version. If you are installing multiple NetWare
4.1 languages, you must repeat the installation procedure described in
Chapter 2. "Installing OS/400 Integration
Products for NetWare".
Installing
Integration for Netware on Multiple Integrated PC Servers on Different
AS/400s
-
-
To install Integration for NetWare on multiple Integrated PC Servers
on different AS/400s:
-
Follow the complete installation procedure as discussed in Chapter
2. "Installing OS/400 Integration Products for NetWare".
-
Save Integration Services for FSIOP, 5763-SA2 using the Save Licensed Program
(SAVLICPGM) command.
-
Restore Integration Services for FSIOP, 5763-SA2 to the second AS/400 using
the Restore Licensed Program (RSTLICPGM) command.
-
Proceed with customizing your NetWare servers, as described either in Chapter
3. "Configuring OS/400 Integration for Novell NetWare" or in Chapter
15. "Configuring Enhanced Integration for NetWare".
Bridging
with a Dual Port file server I/O processor
Two separate physical LANs can be bridged using a two port file server
I/O processor because NetWare routes IPX from one port to another. See
Figure 24-2.

LANs with Dual Port file server I/O processor
