Unable to SSH into Baremetal Instance

mkhan179Mar 21 2018 — edited Mar 29 2018

I have a baremetal Instance and am unable to ssh into it after some time of it's provision. Right after provisioning I can SSH into the machine but after like 15 - 20 mins it says connection timed out. After that I cannot ssh into the machine. The Instance is in running state but cannot ssh into it. I also tried to reboot it but it did not work. Below you can find the ports open in the security list.

I use a terraform script to provision the instance. I add some firewall rules to rules.v4 file in the script - is this causing the problem ?

Interesting question.

I hope to see some informed answers from the big guys ;-)
I'd assume that the placement algorithm will outsmart that approach and keep ressources local to avoid trashing but that might be entirely false or depend on whatever (e.g. ldm version). For fun, I'd check with two bound ldoms. In either case I'd prepare for things being unstable in config space as I am not aware of a vcpu id in the config that might keep such a partition in place across reboots, migrations etc.

If ressources remain unused and license permits, you might look into adding whole cores to your domain and limit thread usage at that level, e.g. disabling and/or assigning cpus to zones or alike.

Are you positive, that your license is based on solaris cpus and not cores? Any hardpartitioning requirement or similar topic that need to be taken into account?

Hi.

Oracle have rules for confugure  LDOM according license policy.

In other cases You can have quiestions about  license rules.
