Primary PxGird Node Selection

[Abhishek Pakrashi]

How to identify which PxGrid node will be the primary.
I understand that by failover, an intended node can be made Primary, but the User guide states: At times, the original primary pxGrid node might be automatically promoted back to the primary role.
So, how can we be sure that the certain node will be primary.

In that chapter, it says,

Note	If pxGrid service is disabled on a node, port 5222 will be down, but port 8910 (used by Web Clients) will be functional and will continue to respond to the requests.

pxGrid version 1 is active/standby so the active pxGrid will accept connections to TCP 5222 whereas the standby not. pxGrid version 2 is active/active and using TCP 8910.

Thus, we may check TCP 5222 availability to determine the active pxGrid v1 node.
