Re: Two node cluster, but only one at a time is up
One of the nodes in the cluster was down so tried to bring up but only one server at a time is coming up. I am sure some setting is missing somewhere or misconfigured. So can you anyone please help!
Following settings I can see from server end:

_Which_ "server"?
Copy+paste with white space works better here with the "</>"
("Insert/Edit code sample") tool.

Re: Two node cluster, but only one at a time is up
Has this been working before ?
What has been changed ?
What has happenend ?
And what happens, if you do what ?
The parameters you've shown have nothing to do with the basic clustering. Consider to show the values for:
VAXCLUSTER, VOTES, EXPECTED_VOTES, DISK_QUORUM, QDSKVOTES, SCSSYSTEMID, SCSNODENAME
from BOTH nodes.
Console messages ?
If it's urgent, consider to log a call with your OpenVMS support organization. This is just a forum...

Yes, was working before. Admin who was maintaining this server left and I was asked to look into it. I am more UNIX person and we don't have support .

Re: Two node cluster, but only one at a time is up
The values of the cluster system parameters are crucial here. Post them from both node - as asked above.
$ MC SYSGEN
SYSGEN> USE CURRENT
SYSGEN> SHOW <...>
Also both systems MUST be able to communicate directly via the LAN.
The console output you've posted is from the 2nd node,? Did you wait long enough (let's say: 5 minutes) ? The 1st node is up and running ? Any messages on the console of the 1st node, if you start (or stop) the 2nd node ? If not, it looks like the LAN communication may not work correctly.
The systems are using LAN failover (at least 3 LAN failover sets: LLA, LLB, LLC). If none of physical devices in the LAN failover set are connected to a LAN segment, which allows cluster communication with the other node, the local system cannot join the cluster. After some time, it may report the other node - based on the data in QUORUM.DAT - but it won't be able to join the cluster without cluster-communication via the LAN.
Volker.

Re: Two node cluster, but only one at a time is up
Hi, Can you please let me know what exact command I can type to get the system parameters as I am not sure?
$ MC SYSGEN
SYSGEN> USE CURRENT
SYSGEN> SHOW <...>
Thank you..
