标题
SPS Managed Host nodes show offline status -
说明
When checking the SPS cluster management page, the Managed Host nodes are listed with Offline status.
Offline status means Status information was sent by the node longer than 60 seconds ago.
-
原因
This can also happen when the SPS node's time is out of sync.
-
解决办法
RESOLUTION:
Go to Basic Settings > Select Date & Time
- Verify if the time is out of sync between each SPS node.
- Add an NTP Server then click Commit then Sync Now.
-Nodes in the cluster connect to each other using IPsec, which requires UDP ports 500, 4500 and 123 (for NTP) to be open in the firewalls between the nodes.
