AS/400 IBM Network Station: Techniques for Deployment in a WAN
standard.nsm
file and then overrides the values necessary to enable Flash
booting. The image was tested by reading the
flash.nsm file
and directing the
Network Station, using NVRAM, to load the files and executable modules
from the test image.
After the Network Station started and functioned correctly from the test
image, the Flash card was formatted and the test image was copied to the
Flash card, using either NFS or the local file manager on the Network Station.
Subsequently, file modifications were made to the
flash.nsm
and
boot.nsl
files
to load the executable modules from the card, rather than from the test image
in the IFS.
The Flash card boot sequence was tested and verified to ensure that the
Network Station was using the Flash card correctly.
Finally, lines that are not required for every day use were removed from the
flash.nsm
file.
The Network Station was restarted again to ensure that the changes to the
flash.nsm
file did not adversely affect operation.
3.4 Peer Booting with 5250, 3270, and VTxxx Support
The availability of Flash card support in Release 3 also brings the added
functionality of starting other IBM Network Stations from a single Flash card.
Peer boot
allows multiple IBM Network Stations located at a remote site (for
example, over a slow or highly utilized WAN) to boot from a single Flash card
located in another IBM Network Station local to them.
Initial start-up performance for as many as 10 IBM Network Stations booting
simultaneously from a single Flash card located in a Network Station on a
LAN is quite acceptable.
When Peer boot is utilized, the peer IBM Network Stations load either some
or all of the startup files and the executable modules from the serving
Network Station, for example, the Network Station with the Flash card.
