Yes, absolutely!
You must keep both SysID & Serial number separate, otherwise Licenses will only show for one node and for other it will appear 'unknown-owner'.
Before running these steps, make a note of sysid & serial number:
One your first cluster simulator:
::>system node show -fields sysid,serialnumber
Make note of the pattern in which they are listed. [Hope you have already added the based cluster license provided by licenses.txt file]
sysid will be like = xxxxxxxxx
serial number wil be like = xxxxx-xx-x
Keep it same, whichever pattern they are.
Steps:
1) Start the 2nd Simulator
2) The moment you see it started, press any key, don't wait for the message that says press CTL+C, we don't need it now.
3) It will bring you to the VLOADER or something.
4) Run following commands:
Run command: set boortarg.nvram.sysid=xxxxxxx
Run command: set SYS_SERIAL_NUM=xxxxx-xx-x
Run command: boot
5) once again simulator boots, this time wait for the ctl+c message and press it immediately.
6) Select the option to erase & wipe, I think (4) whatever it is.
7) once wipe is done, it will bring you back to cluster join or create option, choose join.
Once joined, re-run this command again to ensure the two sysid & serila number are separate.
