Cluster boot problem -DTSS message

nipun_2 — Thu, 31 Mar 2005 18:52:41 GMT

Hi I am starting the new thread to give update of my problem. I am new at the system so if you can please give some detail commands and if you need more info please let me know

I have DS25 and XP1000 (Satellite node) clustered as a common environment with system disk on DS25 and no quorum disk. The system is V7.3-1 and running Decnet Plus. The network is LAN ethernet.

Now I ran Cluster_config to add the new EV68 DS25 station as a satellite node. The configuration completed successfully however when I booted the new satellite node. It went into a "blue screen" and gave DTSS message

Message from user SYSTEM on XXXXX
Event: Too Few Servers Detected from:Node LOCAL:.XXXXX DTSS,

at: 2005-03-31-12:09:21.444-05:00Iinf
Number Detected = 0
Number Required = 1
eventid XXXXXXX....
entityid XXXXXx...
streamUid xxxxx...

This message is for XXXXX = XP1000,DS25 (currently containing system disk) and EV68 (new node)

Ian and Uwe guided me a lot and so I did
to disable on current system
$ MCR NCL DISABLE DTSS on EV68

So this stoped the above messages ONLY from EV68 (new node) rest of the nodes still give the message. When I hit Ctrl/Z "blue screen login prompt comes" and I can log into the system and logout.

As per the suggestion I did

(Ds25 = SC4238)
(XP1000 = SC1000)
(EV68 = SIZZLE)

SYSMAN> DO MCR NCL SHOW DTSS
%SYSMAN-I-OUTPUT, command execution on node SC4238
Node 0 DTSS

Please let me know whether I need to disable the DTSS on all the nodes or some other problem is there. I am also attaching my responses for cluster_config that I did on DS25 for references.

Any and all suggestions are always welcome

Nipun,

There's no problem, other than all of your cluster members are DTSS clients without a DTSS server.

You can use the NET$DTSS_DISABLE logical to disable the client DTSS on all nodes at startup - I suggest to place the definition in SYLOGICALS.COM.

Nipun,

to disable DTSS, you need to add the following command into SYLOGICALS.COM (on each system disk):

$ DEFINE/SYSTEM NET$DISABLE_DTSS TRUE
(NOTE: the logical name in your previous reply was the wrong one)

You could also enable your nodes as DTSS servers, this would cause them to synchronize their time and automatically take care of switching to/from daylight savings time. To do that, you would need to re-configure DECnet_OSI to include DTSS Server.

Indeed, it is a message of DTSS client in DECnet phaseV.
In order to disqualify it you can use:
$ncl
NCL>disable dtss
So that one does not activate in the startup you can comment this line:

ENABLE DTSS SET CLOCK TRUE

in file

sys$startup:NET$DTSS_CLERK_STARTUP.NCL

Hello all,
Thank you for the reply.

I have out of inexperience placed 3 separate links and is creating lot of confusion. Can you please have a look at the most recent updated link

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=847365

I am getting different responses on how to disable DTSS. So I just want to use on detailed approach so I know exactly what I have done. I am new to OpenVMS and I would really like to use this opportunity as an excellent learning experience from all of you.

Nipun,

there is only ONE DESIGNED and SUPPORTED WAY to disable DTSS - add the following to SYLOGICALS.COM:

$ DEFINE/SYSTEM NET$DISABLE_DTSS TRUE

If you don't believe me, have a look in SYS$STARTUP:NET$STARTUP.COM for uses of this logical name. Or do a

$ SEA SYS$STARTUP:*.COM NET$DISABLE_DTSS

Note that you will NOT find anything, if you look for NET$DTSS_DISABLE !

There may be one thousand other ways to disable DTSS through commands here and there, and you could even suppress the DTSS OPCOM message, if you want to.

Volker.

Hi volker,
Thanks for the reply. I am doing the change you suggested to syslogicals.com (I need to see where it is :) ) and change it there. So I will change the previous net $ logical template to what it was before

Can you please repond to the above mentioned link. As I have put too many threads and I might create confusion (which would dangerous for me :)).
