Sun Cluster 3.1 8/05 on Solaris 10 6/06 on T2000 Gotchas?
Hi
I am trying to build a Sun Cluster on 2 T2000, the data services I will manage by the cluster will be Solaris zones which run an Informix DB which has no idea it is running in a cluster.
I have
- installed Solaris 10 6/06
- Applied all patches with TLP (Traffic Light patch management)
- executed the installer which installs the Java Enterprise System
- executed scinstall
- executed scsetup
I then lost the public interface as the router does not (yet) answer a ping, so IPMP assumed the link being down. I disabled IPMP and installed the second node.
Now i have a half living cluster, i can not add quorum device, it dies not find any of the global devices although didadm -l shows them.
A sun engineer recommended a fresh installation which i will do tomorrow, but i am wondering if i missed something else than just the router not replying on a ping request.

So you have a one node cluster with no quorum disk and you can't add any because you can't see any global devices. I've not tried installing a single node cluster recently so I don't know if there are any peculiarities at this point. What message are you getting when you try and add a QD? Are you still in installmode? What is scsetup saying?
The IPMP issue is a red herring, though you will need it working to add services or HA zones. You can always set up pingable host lists rather than have the default router respond. This is documented in an infodoc somewhere.

Hi, Just for all which are curious, there have been 2 reasons for this error which confused me.
1. The router did not response to a ping reply so I got a problem with IPMP during the installation.
2. The SAN switches were incorrect configured, each machine saw just their own SAN disks twice, I did see the correct number of disks, but did not recognize for a long time that I did not have any shared disks.
After fixing this problems, the reinstallation and configuration of the cluster went just fine.
