[HECnet] Cluster annoyances

[Kari Uusim ki]

If you connect the MicroVAX ethernet port to a Cisco switch port, check that the Cisco switch port has spanning tree _disabled_
MOP booting and other low level protocols don't cope well with the spanning tree listening period the switch will enforce when the link is reset.

Hi Cory,

You don't happen to use a Cisco switch when you connect the MicroVAX to your LAN?

Yes, actually. There Are 2 Cisco switches in the way.

Hello all,

I'm trying to get a MicroVAX II to cluster with MORIA.   It's not going so

The moment it joins the cluster, it immediately loses connectivity.
There's between 5 and 10 milliseconds of latency between the two...but
that shouldn't matter...should it?

As I don't have a SCSI Qbus adapter, and I didn't get the TK50+TQK50 with
it, I can only MOP boot it.   60M disk is also not a lot.
