[HECnet] Satellite configuration/NCP crash

[hvlems at zonnet.nl]

I guess so, but remember that a scsi cluster was never possible with a VAX!
The reason for the behaviour is that diskdata and clusterdata   follow different paths in a scsi cluster. Which isn't possible on VAXes (I think). 
Then again it may be a bug in 8.3 of course!

It should happen before disk access across the CI bus is even possible. 


I think we'll have to agree to disagree on this one :-)

I've just booted my Vaxstation 2000 into an NI cluster with my
Vaxstation 3100. I gave the commands:

NCP SET CIRCUIT SVA-0 STATE OFF
NCP SET CIRCUIT SVA-0 STATE ON

on each node. The only effects were an opcom message complaining about
adjacency down and the loss of my decnet connections. Both nodes
continued to function quite happily while the circuit was off. No crash.

Anyway, it looks like avoiding issueing the SET CIRCUIT STATE OFF
command by making the changes to the permanent database and rebooting
was a good way of sidestepping the problem. Hopefully the bug is only
triggered when SET CIRCUIT STATE OFF is issued in Marks setup.

Apologies to gerry77. I missed your reply earlier and ended up repeating
much of what you said.
