Re-cluster 2 HACMP 5.2 nodes
Hi,
A customer I'm supporting once upon a time broke their 2 cluster node database servers so they could use the 2nd standby node for something else. Now sometime later they want to bring the 2nd node back into the cluster for resilance. Problem is there are now 3 VG's that have been set-up outside of the cluster. I've not had to do anything like this before so was wondering if anyone could give me some advice on how to do this? I've made sure both nodes can see all the vpaths needed for the VG's, and the cluster does seem to be in good health. The OS is AIX 5.2.
Thanks
