Node status
The node status identifies the status of the nodes within the system.
Table 1 describes the operational status of a node. To display the node status, issue the lsnode command, use the management GUI, or use the service assistant GUI.
| Status | Description |
|---|---|
| Active | The node is online and can process I/O from hosts. |
| Adding | The node was added to the clustered system but is not yet
synchronized with the system status. The status changes to Online after synchronization is complete. Note: A node can stay in
the Adding status for a long time. Wait at least 30 minutes before you take further action. If after
30 minutes the node status is still Adding, you can delete the node and add it again. If the node
that was 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.
|
| Candidate | The node is not defined in an I/O group; however, it can be added either as one of the node pairs in an I/O group or as a spare node. |
| Deleting | The node is in the process of being deleted from the system. |
| Flushing | The system is removing data from the cache for the node. |
| Online | The node is operational, assigned to a system, and has access to the Fibre Channel SAN fabric. |
| Online spare | The node has been defined to be a hot-spare node and it is being used as a surrogate for another node in the I/O group. |
| Offline | The node is not operational. The node was assigned to a system but is not available on the Fibre Channel SAN fabric. Run the fix procedures to determine the problem. |
| Pending | The status of the node is in transition. In a few seconds, the status of the node will change. |
| Service | The node has been replaced in the system . |
| Spare | The node has been defined to be a hot-spare node; however, it is not being used by the system. The node has a valid cluster ID and a valid node ID. |
| Starting | The node has been restarted. It is attempting to join the system cluster however, it cannot yet perform I/O. |
