Re: Cluster_Config question

Hi Andreas,
Thanks a lot for the detailed message. I am definitely going to check all the details.
Infact I already read through about licensing and now your explanation makes a lot more sense.

However, right now I think I made one error

I was previously trying to modify file
SYLOGICAL and NET$LOGICALS.COM
I needed to shutdown the cluster. I did not want any problems in the already clustered system.So, I deleted the recently edited versions of sylogical and also deleted the earlier versions of net$logical.com (ALL the net$logical.com versions) file.

Now when I started the DS25 (containing system disk) it started fine, then I started SIZZLE just to see what it does...

and it stopped at blue screen

Enter Date and Time (DD-MMM-YYYY HH:MM)?

And then no matter what I entered it gave

Invalid date ????

So I just shut it down and started the XP1000
it started the same problem.

So I copied the Net$logical.template file as net%logical.com
and rebooted the XP1000 and although it started Date and Time (DD-MMM-HH:MM)?

It somehow started the node without any other problems. I was concerned and so I did not want to test it again by rebooting the node withouth discussing in the forum.

So although XP 1000 worked fine SIZZLE still gives the same message Data and Time and would not let me proceed.

Earlier I was able to go to "blue screen" and login and then I could have done above procedures but not anymore.


I think I have gone back one step (I think)because of deleting of net logical file.

So I would like to first solve this issue and understand that XP1000 is properly clustered and then worry about SIZZLE.

If you guys feel rather than modifying contents of net$logical, it would be easier to just remove SIZZLE and add it again, I can do that as well.

Thanks in advance

Re: Cluster_Config question

VMS is asking for the date and time because the one it has (in local hardware clock parhaps) is not valid (or the SETTIME system parameter is set to 1 but thats unlikely).

Enter the date and time in the format shown and it should be fine.

Re: Cluster_Config question

Hello Ian,
thanks for the tip, the system is working fine now. I am currently going through Andreas detailed procedure. From what I have read and understood I think

1) Licensing issue is fine as I have No_share option for PAKs specifically for

SMP and Base are assigned to SIZZLE 75 units which is the requirement

The rest of the licenses that Andreas has mentioned are currently in a common pool. So I believe evertime the cluster starts it automatically assigns itself the remaining licenses. Before I had seen the error message for license and that's how I came to know about registering and loading the SMP and Base license. Final conclusion: License seems fine.

Now the next step should be

looking at Modparams.dat file that Andreas has suggested.


Decnet plus and TCP/IP configuration (I am sure I need to that because of bunch of TCP /IP errors I saw )

So again any comments or suggestions are helpful are highly appreciated. Thanks in advance

Re: Cluster_Config question

Hi Nipun,

Thanks for you feedback.
The system parameter issue is important. Please solve this first.

Anyhow...
Configure TCP/IP first then do the DECnet configuration.

BEFORE you start to configure TCP/IP or DECnet please prepare yourself.
This will make the completion the following tasks successful and straight forward.

TCP/IP
------
- Subnetmask: 255.255.255.0 = C-Net
255.255.0.0 = B-Net
255.0.0.0 = A-Net
select yours...

- TCP/IP Address for SIZZLE or do you use DHCP?
- Default Gateway Address
- TCP/IP qualified name: sizzle.???.???
e.g. sizzle.mydomain.com

DECnet
------
- DECnet nodename = TCP/IP name (max 6 Char.)
- DECnet address: nn.xxx
e.g. 50.199 or 1.3
- in the Network Thread I asked you if you
use DECnet over IP? Do you use it?
Or do you use the DECnet only for the Cluster?

In the meantime I will see if I can provide you with some sample installation captures.
This makes life much easier for you ;-)))

As soon I am ready I will post my results => captures in a new reply.
See you
Andreas

Re: Cluster_Config question

Update1

Hello Andreas,
I have been reading your detailed instructions and trying to implement them. I have following questions

Question 1 : *******
1) Do I need to update network database on the other satellite node XP1000 (SC1004). I have rebooted DS25 (containing system disk) and XP 1000(SC1004) and EV68 (SIZZLE).

I have not done any configuration tasks on SIZZLE so far...

So do I need to do the above

Also

5.10.2 Network Database Files

In OpenVMS Cluster systems on the LAN and in mixed-interconnect clusters, you must also coordinate the SYS$MANAGER:NETNODE_UPDATE.COM file, which is a file that contains all essential network configuration data for satellites. NETNODE_UPDATE.COM is updated each time you add or remove a satellite or change its Ethernet or FDDI hardware address. This file is discussed more thoroughly in Section 10.4.2.

http://h71000.www7.hp.com/doc/731FINAL/4477/4477pro_020.html#maintain_satellite

Question 2 ******
Your documentation is very clear and precise. I am going through it exactly as you have written down.


When I did the
$license modify ...authorization...
followed by
$LICENSE LOAD
I got few errors

NET - APP-SUP-150 unloaded and loaded with 3150 units (Now does this mean all the units have been assigned to SIZZLE instead of other cluster member-if that's the case I will have to change it to just 1050 units....)


OPEN3D LICENSE WAS NOT LOADED

Openvms Alpha both SMP and base were loaded fine

PWLMXXXCA07.03 was loaded and unloaded fine

VMSCLUSTER A0103-CAMPUSWIDE -2066 License has
TERMINATED so not laoded
attempted usage exceeds active license limits

***************8
Question 3:***************

For Modparams.dat

$EDIT SYS$SYSTEM:MODPARAMS.DAT
%TPU-E-NONANSCIRT, SYS$INPUT must be supported CRT

So I have stopped here. I am currently referring to cluster manuals and system managers manual to get a better idea.

Re: Cluster_Config question

Hi Andreas,
Thanks again for the detailed reply.

Regarding Decnet and TCPIP. I am not clear of which I use over which. I do know that we have TCP/IP

People here use FTP and Telnet sessions. When
Cluster_config starts it mentions the node (SIZZLE) is using Decnet plus and Lancp.

$show network
Product:DECNET Node:SIZZLE Address: X.XX
Product:TCP/IP Node: Addresses:0.0.0.0


If I go to other nodes Xp1000 (SC1004) and DS25(SC4238)
$show network
Product:Decnet Node: SC1004/SC4238
Prodcut:TCP/IP Node: (I get a proper name-xxx.xx.xx...) Address: (I get address)

Both the nodes have different node names and addresses.

So I think the systems are commincating over decnet.

Does that answer your question regarding Decnet and TCP/IP

Re: Cluster_Config question

"$EDIT SYS$SYSTEM:MODPARAMS.DAT
%TPU-E-NONANSCIRT, SYS$INPUT must be supported CRT"

VMS does not know what terminal type you have
$ SET TERMINAL/INQUIRE

Remember if you are booting from a common system disk then you can access this nodes files from one of the other nodes.

SYS$SYSDEVICE:[SYSx.SYSEXE]MODPARAMS.DAT

where [SYSx] will be the root for sizzle.

Re: Cluster_Config question

Thanks for the help Ian,
I was able to follow andreas steps from the other node (XP1000).

However I came to SIZZLE for the
$@sys$update:autogen getdata setparams noFEEDBACK

after that I rebooted the system

$reboot

The system started up a bit slowly this time and I was able to read some of the messages going up on the screen...

However, nothing to give me an understanding. Whenver Sizzle boots it goes through the NCL (or NET$XXX)scripts, I can see atleast one file's contents quickly coming up.

Anyway the blue screen still exists.

I saw the "set window_parameter 1" in file setparams.dat


As I mentione before I saw these two errors in

$LIC Load

for Open3d and VMS- cluster license
OPEN3D LICENSE WAS NOT LOADED
VMSCLUSTER A0103-CAMPUSWIDE -2066 License has
TERMINATED so not laoded
attempted usage exceeds active license limits

Note: I believe this would be the update in the permanent database so I am not sure about the volatile database

Please have a look at the update 1 posting above.

that is my update for now.


Andreas, please let me know how you would like me to give you feedback or should I wait till the issue is completely solved. I would be more than happy to give any and all feedback comments.

Re: Cluster_Config question

Hi Nipun,

Attached the promised captures of TCP/IP config and DECnet-Plus Config.
The configuration gets now a little more complex and you need some basic understanding of TCP/IP and DECnet-Plus.
Please ask your Network Admin for assistance. Together you will be able to manage.

Licenses:
== VMSCLUSTER A0103-CAMPUSWIDE -2066 License has TERMINATED (so not laoded)
=> obtain a new license via http://h71000.www7.hp.com/openvmsedu/faq.html (if you qualify for that ;-)) )
== OPEN3D LICENSE WAS NOT LOADED
Eventually the modification was incorrect. try again to modify.

The Licenses are in the LMF DB like in a pool. The NO_SHARE licenses MUST be to a system assigned otherwise it will not work correctly in a cluster.

As Ian mentioned earlier, please do not modify the NCL scripts manually. Use instead the mentioned logicals to disable functions.

This week I am on duty and therefore my time is very limited.
I will try to continue to help. Otherwise, I am sure the colleagues in the forum will assist you.

I hope my suggestions were helpful.
Because of the size I zipped the information (WORD Document)
Good night

Re: Cluster_Config question

Thanks for the files Andreas,
Once I get the Decwindows sorted out. They will be very helpful. You have put in the node name as well, which makes it quite clear. Thanks a lot.


Regarding Clustering.

I had one observation which might be of some importance.

It is regarding the mounted disk

Currently when I go on sizzle and give
$ sh dev /mount sizzle$
It gives me DKA0 and shows as mounted.

However when I go to either of the clustered node, and give the same command. It doesn't show. Is there a way I can atleast have the hard drive mounted in the cluster if not the not DEcwindos. So atleast I can take advantage of the computational resources of Sizzle.

N.P

Re: Cluster_Config question

The blue screen is still on, but since it is already a cluster
Regarding mounting if I go to node

SIZZLE and

give

mount /cluster SIZZLE_7233 DISK3

sizzle_7233 is the volume label

So this would load the disk clusterwide with the logical name DISK3 now EV68 also runs as standalone workstation. In that case when I boot the system from it's local system disk. What will happen to the amount of diskspace??? Would be visible to both or since it will be a different volume label it will have different amt available ??

I was looking at system manager's manual which showed the above commands but was not very clear about the size

My objective here is to atleast make the resouurces hard drive and CPU resources available to the cluster for now

Re: Cluster_Config question

I just noticed N.P. Actually that is my colleague working on a problem of networking. I think we logged into the same machine. I aplogize for discrepancy.

Re: Cluster_Config question

Thank you all for your reply.

All the details really helped me to get to know the system much better and do many of the operations you have suggested.

Although the dec windows problem is still not solved. I will try to put in more specific problems as a new thread and try to isolate the problem.
