Using the
flashupdate
Command
The
flashupdate
command requires that the SC 10/100BASE-T Ethernet port is
connected to a suitable network and is configured so that it can see an external FTP
or HTTP server that contains the new firmware images to be downloaded.
The
flashupdate
command updates the flash PROMs in the SC and the system
boards (CPU/memory boards and I/O assembly). The source flash image is
normally held on an NFS server. In the case of CPU/memory boards you can update
one board with the flash image from another.
The syntax for the
flashupdate
command is:
flashupdate [-y|-n] -f
url
all|systemboards|scapp|rtos|
board
. . .
flashupdate [-y|-n] -c
source-board destination-board
. . .
flashupdate [-y|-n] -u
where:
■
-y
does not prompt for confirmation.
■
-n
does not execute this command if confirmation is required.
■
-f
specifies a URL as the source of the flash images. This option requires a
network connection with the flash image held on an NFS server. Use this option
to install new firmware.
