3301.0. "DS90l+ not managable" by PRIVAT::OTTO (getting better all the time) Wed Feb 21 1996 11:20

Hello

A customer has Hubwatch 4.1.1 on Windows 3.11/Pathworks 5 and 
reported this problem.

He has two Hub90 Backplanes with the following Config:
Backplane 1:

slot 1 DECserver90L+ V4.9
slot 2 DECserver90L+ V5.5
slot 3 DECserver90L+ V5.4
slot 7 DECbridge90

Backplane 2:

slot 1 DECserver90L+ V5.4
slot 2 DECserver90L+ V5.2
slot 3 DECserver90L+ V5.2
slot 8 DECagent90 V3.0.1


He tries to manage the DECserver90l+'s  for Example change the Port Name or 
disconnect a port.

This works only on the DECserver90l+ in Backplane 1 in Slot 3 (5.4)

on all other DECserver90l+ he gets an alert Box from Hubwatch


"Hubwatch Error"
"Generic Error SNMP Response"

In the Message Box window no errors are displayed.

I have Hubwatch 4.1.2 on windows 3.11 and Hubwatch 4.1.1 on DEC UNIX 
and the one and only DECserver90l+ is V2.0 Bl5.4 gives no Problems 
at all i.e. I can manage anything that is possible.


Any Ideas what I should check ???



Thanks

Two things to look for:
(1) Does the DECagent 90 know the DECservers in backplane 1 exist?
    Have they been correctly added (using the Configuration->Add Module
    screen in HUBwatch).

(2) Were the MAC addresses for the decservers entered correctly?

From your description, it sounds like only one of the DECservers was 
entered correctly. Also, if any of the 90L+'s are more than a few years
old, they are not autodiscovered by the agent, even if they're in the
same hub.

Just to add a few more words to Tom's comment on auto-discovery.  There are
really TWO different DS90L+'s in the world.  They can ONLY be definitively
identified by looking at their dataplates.  Those with a revision B02, C02, or
D02 are auto-discoverable.  Those with Revision A01, B01 or C01 are NOT.  Please
note that the difference is the "01" and "02" portion of the revision - NOT the
letter.  If you cannot unplug the unit from the hub to examine it, you have
SOME possibility of figuring this out by examining firmware revs.  The firware
rev gives an indication of the vintage of the server and can be used for an
approximation of hardware rev.  Please note that what is important is the
HARDWARE rev.  Upgrading the firmware will not install a feature that the
hardware does not provide.

Servers BUILT with 4.9 ROMs are OLD and will NOT autodiscover.  Those built with
5.2 WILL.  5.4 was retrofitted into both types so they are a toss-up.
Officially, 5.5 was ONLY installed in Rev D02 hardware so they SHOULD
autodiscover.  The rev *01 servers are no longer built, repaired, or supported
so they will ultimately disappear.  However, there were tens of thousands of
them built so it'll take a while 8^).
