1904.0. "Trucluser and question" by DEKVC::JUNMOKSONG () Thu Feb 27 1997 00:34


    Hi,
    
    Thank you for your support.
    
    I had two questions about trucluster function as following:
    
    1. I configurated Trucluster with two 8200 which have two Memory
       Channel and FDDI network for client and so to test user login
       servic I define login service as login_test and when I take 
       the FDDI line off from FDDI card within system, the client can't
       access the another system by login_test. It maens the client
       can't login all member of Truclusetr. the login service didn't
       work.
    
       So I think Trucluser doesn't know member of Trucluster is disconnect
       from FDDI network. But when I relocate the login service by asemgr, 
       that is O.K and also when I shutdown one member of Trucluser which is 
       high favor member, client can login the another member by login service.
      
                          M.C
		memberA -------- memberB
                  |      -------- |<------------ I took it off to test
                  |---------------|              login service by network
                        |                        disconnect.
    			|    FDDI

                 memberA    : 12.26.84.1  
    		 mcmemberA  : 15.0.0.40
                 memberB    : 12.26.84.2
                 mcmemberB  : 15.0.0.41
                 login_test : 12.26.84.3
                 netmask    : 255.255.255.0     
     		 client     : 12.26.84.4
    
       I wonder if my test is normal or abnormal. How can I set login service 
       up using FDDI?
    
    
    2. I want to know the meanings as following messages which occurs 
       every 20 seconds on both of Trucluser member:

Jun-Mok,

1. Modify your network set in the asemgr utility (ie. run the a) and
   then n) options).  ASE does not detect that this interface can not
   talk and operate on the state change by default.  You need to add
   this interface (and corresponding ones for all members) to the ASE
   network onfiguration as a monitored interface.  When all monitored
   interfaces fail, the ASE services fail over. 

2. These appear to be the result of running the cluster monitor.  If
   you are running cmon, this would explain them.  The cluster monitor
   runs the asemgr command to get the state of the ASE for its display.

Regards,

    Hi,
    
    Thank you for your answer.
    
    We have already configurated the FDDI monitored but this error
    happened. I now knew the ifconfig command was set in start script 
    by "ifconfig alias fta0 alias shareloginname netmask 255.255.255.0"
    
    and so we will set this by "/var/ase/sbin/nfs_ifconfig $$
    start ${svcName} returnValue=$?"
    
    What do you think of this?
    
    And I will try ty cmon and can I get the documentation about it?

1904.3This test case should workNETRIX::&quot;myrdal@zk3.dec.com&quot;Gregory P. MyrdalTue Mar 04 1997 14:5925
    and so we will set this by "/var/ase/sbin/nfs_ifconfig $$
    start ${svcName} returnValue=$?"

This looks ok, I created a login service as used the following 
in my start script:

/var/ase/sbin/nfs_ifconfig $$ start $svcName
exit $?

Unfortunately I do not think it will fix your problem.  Your ifconfig
line looked ok.  I set up a login service and your example worked for
my case.  The only problem is, I did not have fddi to test it out on.  I 
had to use ethernet.  This should work, if it does not for you a QAR should
be filed.

    And I will try ty cmon and can I get the documentation about it?

Try the Cluster Monitor manual pages:

1904.4More questionDEKVC::JUNMOKSONGTue Mar 04 1997 22:2316
    Hi,
    Thank you for your answer.
 
    I have more question about "all monitored interface fail".
    What does it mean? In my case, we had two MCs and one FDDI 
    and so I wonder if all monitored interface contain the two
    MCs and one FDDI and ans consequently you mean only if two 
    MCs and one FDDI are disconnected or failed the login service
    can be failover in Trucluster.
    
    Thank you for cm message WEB site.

    Best Regards,

1904.5We relocate services when all monitored interfaces failNETRIX::&quot;myrdal@zk3.dec.com&quot;Gregory P. MyrdalWed Mar 05 1997 17:4321

A monitored interface is one in which you set to be monitored
in the asemgr network modification menu.  By default we do not
set the MC networks as being monitored.  Since clients do not
hang off of this "network" it is not useful to determine what do
do with services if one of them fails.  In your case I would only
set the one fddi as being monitored.

Yes, the entire set of monitored interfaces have to fail in order for
services to be relocated.
