HACMP path-ownership rules

Jump to solution

Hi experts,

I've got a couple of AIX NetWorker (8.0.3) clients running on IBM AIX (7.1) cluster (HACMP). NetWorker backs up both the physical and the virtual nodes. Everything works well.

Recently we've added new HACMP clients. They are failing with the following message:

cl-xxx-vip01.fqdn.ch:All 7184:savefs: nothing to save

One of the physical node is backing up filesystems associated with the both the physical and the virtual node. The second node backs up only its physical filesystems.

The file "pathownerignore" is not set on any of the cluster nodes.

Does anybody have an idea what goes wrong?

Thanks & Regards

Christian

Been there

Are these paths NFS or FC?  Anyway, before we get to that, the trick is to run networker.cluster first.  This will create /bin/lcmap.  This alone might not be enough depending on how cluster is configured because if you manually run /bin/lcmap you might get an answer that ownership is under hostname and you have FQDN defined on server side.  To fix that, you will need to edit /bin/lcmap and add domain to iplabel line somewhere towards the end.

Now, this will work just fine with FC. With NFS it won't so there you will need to additionally define save sets instead of using save set All.

Hi Hrvoje,

you got it! AIX admin forgot to run the networker.cluster script. After completion of the script the resource groups and corresponding VIPs could be identified and backup completes successful.

Many thanks

Christian
