For the DECnet cluster alias you need (at least) one routing node (L1) or a router. Does any of the cluster nodes have routing enabled?

I guess you have a DECnet router involved, but just asking.

The booting/sharing/clustering works as usual (that is, awesomly), but I can't make the decnet cluster alias work. I have defined it and if I do a show exec char I see it is defined. If I do a SET HOST to the cluster alias _FROM_ any node in the cluster, it also works (as SET HOST 0), but the address does not propagate thru the LAN, so it is not visible in SHOW NET/OLD and it is regarded as unreachable from any other node.

Since DECNET has no ARP resolution I guess the MAC address corresponding to the DECNET address is somehow added to the NIC so it "listens" to both MAC addresses (the one corresponding to the node and the cluster one). Perhaps SIMH implementation does not allow this magic. If that was the case I'd consider it something to be fixed. Any idea if I am missing something stupid before reporting this as a bug?

DEC Information Source

by Paul_Koning＠Dell.com

Interesting! I see 4 manuals for the DECmpp . That looks familiar, but I though that this was only a design circulating around DEC and not something that ever became a product. It looks like it did. Up to 16 processor cards with 1024 processors each. Neat. paul On May 21, 2014, at 1:44 PM, Mark Wickens <mark at wickensonline.co.uk> wrote: Came across this link: http://decdoc.itsx.net/dec94mds/

Never seen one of these in the flesh before...

Well, that was a decent price, but that won't last long. There are others as well, but at really different prices: http://www.ebay.co.uk/itm/251516666655?_trksid=p2055120.m1438.l2649&ssPageN… Kari On 21.5.2014 21:37, Mark Wickens wrote: On 21/05/2014 19:35, Kari Uusim ki wrote: They are horribly expensive - as they were as new.
