The S10 node status is showing as Invalid while all hardware components are running fine.
Below are the two S10s configured in the same storage pool.
This particular screenshot is a 220.127.116.11 instance
This is a known issue, and is only cosmetic. The 'invalid' state does not actually prevent any data access, meaning that you can use the HCP and S10 node normally. It is fixed in the 7.2.1 release.
Upgrade to 7.2.1 and the invalid state will go away.
