Hello all,
I would like to provision some new nodes in my xCAT cluster inside VMWare
but I just realized that the way xCAT has identified and discovered my
nodes in the past has been by dedicated physical port numbers on the
switches as defined in the xCAT switch database table. That is not a
problem for physical nodes which have a single cable going into a port on a
switch dedicated only to that node.
For example one of my nodes has this entry in the switch table:
#node,switch,port,vlan,interface,comments,disable
"hinode","bnt01","44","1","eth0","bnt01:p44"
This tells xCAT that the node found connected to port 44 on switch bnt01
can be identified as node "hinode". With a VMWare cluster however a VM may
reside on many ports (in my case I have 3 ESX servers - and 3 corresponding
cables to the switch - which the VM may be on) at any given time, depending
on which VMWare host it is running on. And on top of that the network
connection is trunked so that every VM running on each ESX host goes
through the same network port.
Has anyone provisioned nodes in VMWare before with xCAT? And if there is
not a way to do this automatically by the switch/port associations, is
there another manual way that I can discover the node? Would manually
inserting the node's MAC address into the xCAT 'mac' table work, or is more
than that required for (auto)discovery?
Thanks,
Josh Nielsen
