interdependences on Clusters

[MirkoW]

Hi,

i use 2 Servers combined in a Cluster.

ony one Service that exist on all Servers does running.

so if ServiceXY running on Server 1 so ServiceXY does not running on Server 2

i have create a service-test in HM for each Server and add dependencs to the Services

Server1 - ServiceXY dependes on Server2 - Service XY with "Dead" or "unknown"

and

Server2 - ServiceXY dependes on Server1 - Service XY with "Dead" or "unknown"

but the both service-tests display only "Wait for Master"

whats wrong?

As I can see, you made cross-reference between services. ServiceXY on Server 1 depends on ServiceXY on Server 2 and vice versa, right? Not sure it's a good idea. It appers to be endless loop. I think, you should take something more reliable as a master test. For instance - check active node. Are you able to distinguish what server is active node in a cluster?
Probably, folowing article might help: http://www.ks-soft.net/cgi-bin/phpBB/vi ... php?t=3977
In this article you may find script to get active node.

Hi,

thanks for Info..

i modify the script sample to use it as shell script with param:

Params: Cluster-Server

Code: Select all

const statusAlive       = "scriptRes:Host is alive:"
const statusDead        = "scriptRes:No answer:"
const statusUnknown     = "scriptRes:Unknown:"
const statusNotResolved = "scriptRes:Unknown host:"
const statusOk          = "scriptRes:Ok:"
const statusBad         = "scriptRes:Bad:"
const statusBadContents = "scriptRes:Bad contents:"

Dim strComputer,objArgs
Set objArgs = WScript.Arguments
strComputer  = objArgs(0)

Dim objCluster 
Dim strTestname 
Set objCluster = CreateObject("MSCluster.Cluster") 
objCluster.Open strComputer 
strOwner = objCluster.ResourceGroups.Item("Cluster Group").OwnerNode.Name 
Set objCluster = Nothing 
WScript.StdOut.Write statusAlive & strOwner

Good job!
So, have you managed to make dependencies working?

yes, i have add a service-test on cluster instead of every server. so i know if this service is running
