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.

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


* figure task not displayed.
To install Integration for NetWare on multiple Integrated PC Servers on different AS/400s: 
  1. Follow the complete installation procedure as discussed in Chapter 2. "Installing OS/400 Integration Products for NetWare"
  2. Save Integration Services for FSIOP, 5763-SA2 using the Save Licensed Program (SAVLICPGM) command. 
  3. Restore Integration Services for FSIOP, 5763-SA2 to the second AS/400 using the Restore Licensed Program (RSTLICPGM) command. 
  4. 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
