AS/400 IBM Network Station: Techniques for Deployment in a WAN
If each user using different functions, for example one person requires the
Netscape browser, while another requires 5250 and 3270 emulation, then
these modules should reside on the Flash card to reduce network traffic
and load time.
• Is there a mixture of Series 100/300 and Series 1000 Network stations
peer booting from the serving Network Station?
If there is a mixture of Series 100/300 and Series 1000 Network Stations,
should more than one serving Network Station be deployed. Series 1000
requires a different kernel (and other modules) which can exceed the size
limitation of the Flash card.
It is recommended that the Series 1000 Network Stations peer boot from a
separate serving Network Station.
• Is redundancy required?
If all of the people in the remote office are peer booting from one Network
Station, then, this system is a single point of failure. A back up Network
Station, already configured with another Flash card, should be ready for
use if the need arises.
3.5.2 Modifying Existing Flash Boot Network Station Configuration
This scenario assumes you have already configured and tested, or have an
existing Network Station that boots or starts from an installed Flash card. If
you have not already done so, refer to Section 3.2, “Booting from a Flash
Card with 5250, 3270, and VTxxx Support” on page 69.
A change must be made to the
flash.nsm file which is read from the central
AS/400 system. This file must be edited to allow peer boot support.
Use the following steps to enable peer boot support on the serving Network
Station which already has the Flash card installed:
1. Edit the file
flash.nsm , which is located in the directory
/QIBM/ProdData/NetworkStation/configs. Add the following lines of text
after the
read standard.nsm statement:
set file-enable-nfs-server = true
set file-export-directory-list = { { "/peerboot" "/local" } }
set file-nfs-access-control-default = read-only
2. Close and save the file.
3. Restart the Network Station that contains the Flash card to invoke the NFS
server daemon.
