[HECnet] Asymmetric connectivity in a cluster

I agree with you, on the other hand they should be consistently the wrong thing in consistently the same way L

I?m not sure that asymmetric is the correct description but I can?t ??? think of a better term. I am using SIMH and I have a two node ??? cluster (with a quorum disk) the two nodes have a common system disk. ??? The two nodes are RODNEL (1.1) booting from SYS0 and ADV2 (1.3) ??? booting from SYS2. Both are running DECnet Plus both are running ??? Multinet for the IP stack. At one time there was also a node (never ??? actually a member of the cluster called HCBVAX (1.2) it booted from ??? SYS1 but it no longer exists. ??? The nodes are connected over an Ethernet and the MAC addresses are ??? the ones that I would expect AA-00-04-00-01-04 (1.1) and ??? AA-00-04-00-03-04 (1.3)? HCBVAX was AA-00-04-00-02-04 (1.2) ??? I can login to RODNEL and ?set host adv2? with no problem, I can ??? login to ADV2 and ?set host rondel? with no problem. On each of the ??? nodes I can ?show cluster? and I see what I expect to see with no ??? errors. While logged in to RODNEL the command ?moni cluster? works ??? fine. While logged in to ADV2 the wheels seem to fall off the bus ? ??? ?show cluster? is fine but ?moni cluster? isn?t Any help would be ??? appreciated. This is the information that I have gathered so far (I ??? am not happy with the forwarding address in the error message from ??? ?moni proc? on ADV2 which seems to arise from RODNEL ??? --Dave ???
