Testing this AM
I booted the fresh VSI install and started DECnet.
Decnet IV works.  I can set host and copy files to the test Alphaserver on the network.
SYS$EIDRIVER reports Ident X-5, Link date 27-JUL-2016 10:30:17.55, Build Ident  XE3A-H4N-000000

TCPIP also worked.


Then booted the upgraded system disk (HP V8.4 to VSI)

SYS$EIDRIVER is the same image version and link date (from 2016) on both system disks.

The LANCP internal counters show the same thing referred above; the upgrade system has a rising carrier check failure count, and zero packets received/sent, the VSI installed system shows normal data counters and no errors.  

I did not boot the original (restored, pre-upgrade) HP V8.4 disk  but it did work fine a couple of weeks ago, the first time since we used DECnet to make network backups over to the test alpha (safety copies) prior to upgrading; this after modifying the system to handle the different device names on the new server.  I'll try overlaying the parameter file later if time and interrupts allow.  Ditto for SDA output; I dumped the upgraded system's SHOW LAN/DEV to a file to review but my internals and crash dump analysis days ended 15+ years ago; we'll see what we can make out.   The TRACE output mostly shows a series of Check Link entries with occasional Transmit Errors.

And sorry.  I must have misremembered with all the testing and reboots.  TCPIP does NOT work on the system that was upgraded from HP V8.4 to VSI V8.4-2L1.  It has barely been used since DECnet is so much easier moving files back and forth from the test Alpha that has connections to the main network.  The new RX2800 is on an isolated network with no direct outside access.

I threw the question out here after getting yanked off this work too many times and misquoted my notes.  So both DECnet and TCPIP are down after the upgrade.  Tried testing with LAT also after enabling outbound connections on both machines, and they can't see each-other.

So its not a DECnet specific issue.
