Managing Microsoft Message Queuing in a cluster remotely

Ever had the problem when you’ve only got remote access to your cluster nodes and you need to modify a clustered MSMQ instance, but the tools just won’t connect to the correct instance, even when you’ve tried the set computername command prompt trick, you can’t use mstsc /console or you’re stuck on Windows 2008R2 and you don’t have the manage option on right click in Failover Manager.

Make your life so much easier by getting a nice simple free tool from Microsoft MMCV –

CRM Dynamics 2011 on an Amazon EC2 instance

It’s always handy to have a well sized Dynamics CRM install to hand, that’s quick to reset, and cheap to take with you for demos. By far the cheapest and easiest way I’ve found for doing this is using Amazons EC2 system. I only have to pay for when I use it, which at time of writing is about

Matching windows cluster node ID to physical server

So you’ve built your Windows 2008 Cluster, and you did it sensibly with good logical names like

  • cluster-node-01
  • cluster-node-02
  • cluster-node-03

It’s been running quite happily, you’ve extended it and upgraded it. But now you’ve got a problem, a resource won’t start up when it’s moved to a new node. So you’ve followed the instructions to get the last 5 minutes of Cluster logs by running:

C:\>cluster log /gen /span:5

And you’ve found that the error is something to do with:

00000790.0000545c::2012/01/09-11:16:15.778 ERR   [RCM]s_RcmRpcGetResourceState: ERROR_CLUSTER_GROUP_MOVING(5908)' because of ''Cluster Disk 3' is owned by node 4, not 6.'

But wait a second, what’s this node 4 and 6 business? And which node is the one causing the problem?

The simplest way to find out which node is which is to simply drop to a cmd prompt on one of the nodes and:

C:\>cluster node /status
Listing status for all available nodes:

Node           Node ID Status
-------------- ------- ---------------------
cluster-node-04      1 Up
cluster-node-02      4 Up
cluster-node-01      5 Up
cluster-node-03      6 Up

C:\>

And there you have a nice little lookup table for you.

But why aren’t they aren’t the in nice logical order you installed them in? Well, remember that time you had to evict cluster-node-01 because of the main board fault and rebuilt it on new hardware? Or when you upgraded the hardware by adding in a new ‘better’ node and then removed/replaced the nodes 1 by 1.

Every time the Cluster sees a ‘new’ node it assigns it a shiny new Node number. So when you first built the cluster it was a nice correlation. But the good news is that as it’s going to change fairly infrequently it’s pretty easy to keep a track of it.
