Re: TSM client on a Netware Cluster

[Andrew Ferris]

Hi Timothy,

Here's how we do it on two clusters with 4 and 16 cluster volumes:

TSM on a Netware Cluster

Assumptions:
TSM Clients on NetWare servers already running
Client nodes and schedules for cluster backups defined in TSM
SYS:/ETC/SMS/TSA.CFG has “Disable Cluster” value set to “yes”
Up to date on TSAFS and SMS patches

Create a /Tivoli folder in the root of all clustered volumes. This is where the 
clustered clients will live. 
Copy over every file and folder from SYS:/TIVOLI/TSM/CLIENT/BA (or wherever the 
server TSM clients are) to the /Tivoli folder except these:

TSM.PWD
*.log
dsm.opt

Rename the “DSMCAD.NLM” file to something like “DSMCAD-CV01.NLM”. 
In other words make each cluster node’s DSMCAD unique. 

Create a dsm.opt file for the clustered resource. Here’s an example:

******************************************************
*  TSM Config file for [ClusterVOL01]
*  -------------------------------------------------------

  COMMMETHOD                TCPIP 
    TCPSERVERADDRESS         tsm01.mrl.ubc.ca
    TCPPORT                  1500

  NODENAME                  [ClusterVOL01]

  HTTPPORT 1611
  ERRORLOGRETENTION 7
  SCHEDLOGRETENTION 7
  MANAGEDSERVICES WEBCLIENT SCHEDULE
  DOMAIN [ClusterVOL01]
  CLUSTERNODE YES
  PASSWORDDIR [ClusterVOL01]:\Tivoli
  PASSWORDACCESS GENERATE
  NWPWFILE YES
  ERRORLOGNAME [ClusterVOL01]:\Tivoli\dsmerror.log
  SCHEDLOGNAME [ClusterVOL01]:\Tivoli\dsmsched.log
  SCHEDMODE POLLING 
  NWEXITNLMP NO

*******************************************************

The dsm.opt file should have a different “HTTPPORT” value for each cluster 
resource such as:
[ClusterVOL01] 1611
[ClusterVOL02] 1612
[ClusterVOL03] 1613
[ClusterVOL04] 1614

The “CLUSTERNODE” value should be “YES”.
THE “NWEXITNLMP” value (aka press any key to close) should be “NO”

We have an account with read rights to all clustered objects and servers (i.e 
their OU). 
Let’s call it “backer.users.ourOU”. Use this account with all TSM clients. 

Run “[Path:/to/]dsmc -optfile=[Path:/to/dsm.opt]”
Enter “q tsa” on command line.
If it asks for a NetWare account and password then use the “backer” account.
If it doesn’t ask then the output should look like this:

tsm> q tsa                                                        
NetWare TSA Information                                           
                                                                  
TSA Name................: [Server_Name]                              
TSA Module Name.........: TSAFS.NLM                               
TSA Version.............: 6.57.1                                  
SMDR Version............: 6.57.1                                  
User/Password Location..: [ClusterVOL01]:/TIVOLI/TSM.PWD       
User/Password Valid.....: YES                                     
                                                                
Modify the cluster resource’s load and unload scripts. 
Add these entries to the end of the cluster volume’s load script:

delay 5
load [ClusterVOL01]:\tivoli\dsmcad-CV01.nlm 
-optfile=[ClusterVOL01]:\tivoli\dsm.opt

Add the entries to the start of the cluster volume’s unload script:

unload dsmagent
unload dsmcad-CV01
delay 2

The “delay” values may to be tweaked to add more time depending on the nature 
of cluster resources.

The above setup means that cluster resource CADs will follow their cluster 
object as it loads and unloads. Bad things will most likely happen if you try 
and move a clustered resource during a backup so I'd advise against that. But 
other than that everything been fine for us.

Hello,

About 2 years ago we tried unsuccessfully to implement a Novell
Tivoli client Cluster in a Netware environment. We are going to try
to implement this again,  Does anyone have a working  Novell cluster and
can offer any advice, Tips or dsm.opt file (s) examples of this is
implemented?
Or If there anyone knows where I can get some good documentation
on how to configure the backup-arhive client in a Novell cluster
environment outside of the documentation thats in the Novell client guide it
would be appreciated, From what I understand it would be on 6 cluster
services.


Thanks for any help or advice in advance!
