Each single processing unit is a node canister, which is also called a node. The two nodes within the enclosure make an I/O group that connects to host systems and optionally, to external storage systems.
| State | Description |
|---|---|
| Adding | The node canister was added to the clustered system but is not yet synchronized with the system state. The node canister state changes to Online after synchronization is complete. Note: A node can stay in the Adding state for a long time. Wait at least
30 minutes before you take further action. If after 30 minutes the
node state is still Adding, you can delete the node and add it again.
If the node that has been added is at a lower code level than the
rest of the system, the node is upgraded to the system code level,
which can take up to 20 minutes. During this time, the node is shown
as Adding.
|
| Deleting | The node canister is in the process of being deleted from the system. |
| Online | The node canister is operational and is assigned to a cluster. |
| Offline | The node canister is not operational. Run the fix procedures to determine the problem. |
| Pending | The node canister is transitioning between states and, in a few seconds, will move to one of the other states. |
