Yatindra is trying to deploy StarlingX in Simplex mode.  I got the following email today.  Can we please give him some guidance as to how to get the system up and running?

Thank you!

Simplex:   Controller-0 configuration was success.

- Was able to provision controller-0 host as per the StarlingX Installation Simplex link. But after unlocking controller-0 as per command “[wrsroot@controller-0 ~(keystone_admin)]$ system host-unlock controller-0”,  system get rebooted and unable to get to the login screen giving  error like in the attached image(stx_reboot_connect_issue)  . It is like “State change failed: device is opened by someone”.

- Reboot takes multiple time and once after 5 times it reached to login screen. Then when I checked status about the controller-0 “[wrsroot@controller-0 ~(keystone_admin)]$ system host-list”, in the availability column it says degraded. See Last command in the link.

- I tried re-installing, but faced another issue about LVM storage backend remaining in the state of configuring for longer time, hence failing to provision controller-0. Please look in the attached image(stxissue_simplex_lvm_configuring) which is output  of command [wrsroot@controller-0 ~(keystone_admin)]$ system storage-backend-list” for better understanding. When I run command “[wrsroot@controller-0 ~(keystone_admin)]$ system storage-backend-add lvm -s cinder --confirmed” there was some issue related to connecting to controller-oam interface. As LVM-storage backend state remained in the configuring state for long time, I tried to delete it which was not possible and neither it allowed me to create another.
