Change the ID of a SVC Node

Hi Folks,

I'm currently in a position where I am building the seed equipment for a Data Centre Migration, I'm familiar with some of the equipment - all of which I've listed below.

SAN Storage - EMC VNX5800
SAN Switches - Brocade DCX 8510-4
SAN Management - IBM SVC 2145-DH8 four node cluster
AIX Tin - IBM S824 * 3
AIX Tin Management - HMC
Oracle Tin - T5-2, T5240 and v890

All the storage connectivity is 16Gb Fibre and all the network connectivity is 10Gb Copper and Fibre mix - except the management Vlan which is 1Gb Copper.

Most of the equipment I have helped setup or setup myself (I'm mainly a Solaris/Storage person), a colleague has setup the rest of the tin - with the exception of the SVC which was setup by IBM.

To a some extent this replicates the current estate, this has all been done in preparation for a migration event.

However at the last minute I have found a discrepancy in the SVC build, this isn't a major problem. The problem is just the numbering of the nodes, discovered during testing as follows.

The original SVC cluster has nodes identified as 1,2,3 and 4, the new cluster has nodes identified as 1,2,5 and 6. The question is, is there a simple way if re-numbering nodes 5 and six to be nodes 3 and 4 respectively, or do I have to destroy the cluster and rebuild.

The SVC nodes are running 7.6.0.1

votequorum_leaving

VOTEQUORUM_LEAVING(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_LEAVING(3)

NAME

       votequorum_leaving - Tell other nodes that we are leaving the cluster

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_leaving(votequorum_handle_t handle);

DESCRIPTION

       The votequorum_leaving function is used to tell the other nodes in the cluster that this node is leaving. They will (when the node actually
       leaves) reduce quorum to keep the cluster running without this node.

       This function should only be called if it is known that the node is being shut down for a known reason and could be out of the cluster  for
       an extended period of time.

       Normal behaviour is for the cluster to reduce the total number of votes, but NOT expected_votes when a node leave the cluster, so the clus-
       ter could become inquorate. This is correct behaviour and is ther eto prevent split-brain.

       Do NOT call this function unless you know what you are doing.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.

ERRORS

       The errors are undocumented.
