Title: [DECndu Plus] How To Upgrade DECagent 90 Firmware Via TFTP

Question:

How do you upgrade the firmware on something like a DECagent 90 via the
TCP/IP TFTP, Trivial File Transfer Protocol, from an OpenVMS VAX systems?


Answer:

The first requirement is that the OpenVMS VAX system be running at least
V2.0 of TCP/IP Services, UCX.  The next thing that is required is that the
DECagent 90 must be running at least V2.0 or greater of the firmware.  To
check the revision level of a DECagent 90 or any other SNMP capable system,
the DOWNLOAD SHOW DEVICE command can be used as the following illustrates:

The next step is to perform the actual firmware upgrade procedure.  In the
case of the DECagent 90, the MOM$LOAD:DENMA.NDU_SCRIPT file that comes as
part of the DECagent 90 firmware update kit must be appended to the
SYS$COMMON:[SYSEXE]NDU$SDDF.STP file.  The easiest way to do this is by
using the DCL APPEND command.  The next bit of information that is required
is the SNMP write community string name.  The following illustrates an
actual firmware update procedure involving a DECagent 90 as the target:

===============================================================================

$ DOWNLOAD LOAD /FORCE=decagent /PASSWORD="write-community"
_Target name: 16.72.112.230
_Image filename: MOM$LOAD:DENMA021.SYS

===============================================================================

As can be seen by the contents of the SNMP variable "sysDescr", the
firmware has been updated.  It should be noted that this final bit of
information may take a little while to be displayed as the unit will have
to reboot itself.

The value used for the /FORCE qualifer will depended up the actual target
device.  The contents of the file SYS$SYSTEM:NDU.SDDF.STP can be examined
to see what "DEVICE" can be supported.
