3540.0. "Unable to delete LAN Segment in Hub900 after Firmware Upgrade" by PRIVAT::OTTO (getting better all the time) Mon May 20 1996 05:16

Hello

a customer did a Firmware Upgrade to V4.1.0 on Nine HUB900.
All Hubs where updated using HUBLOADER on a PC running WINDOWS V3.11.

All Hubs where factory reset and newly setup. The Lan/FDDI Segments 
where recreated from scratch.
This was ok on eight Hubs.

But one Hub gives the following problems. 
Before the Update was done, the Ethernet-LAN Segments (three) where named as 
follows:

E_H1_11 
E_H1_12
E_H1_13


after the Update was done and after a Factory Reset of the Hub was done 
there was a Ethernet LAN Segment called 

E_H1_121_11

This Segment is not removeable, it is not possible to connect any Lan Port 
to it, it even remains there after a Factory Reset.
When trying to remove it the customer gets a "HUBWATCH Error delete failed" 
When trying to connect a LAN Port from a repeater to it the customer gets a 

"HUBWATCH Error  Add failed"
There is no Trace of Error in the Message Box from Hubwatch.

The Hub is populated as follows:
slot 1 DECConcentrator 900MX
slot 2 DECSwitch900EF
slot 3 DECSwitch900EF
slot 4-7 DECreepeater900TM
slot 8 DECserver900TM



Can this be a Hardware Error in the Hub that only showed up due to the new 
Firmware ?
What other posibilities do I have to get rid of this beside changing the 
agent/Backplane ? 



Thanks 

OTTO

	The LAN segments are stored in non-volatile RAM in the hub's management module. When you do a "reset to factory defaults" all this non-vol memory is erased. Therefore you should not have any LAN segments left over. I can think of two possibilities: 1) There is a hardware problem in that non-volatile ram that causes it to malfunction and not be erased when you do a "factory reset". 2) You need to press the "refresh" button on the lan interconnect in hubwatch (or exit hubwatch and start from scratch).
