The node state
Learn how to find the state of the nodes in an IBM Storage Scale cluster.
To check the node state, issue the mmgetstate command
with or without the -a option, as in the following
examples:
1) mmgetstate
2) mmgetstate -aBe aware of the differences between the down, unknown,
and unresponsive states:
- A node in the down state is reachable but the GPFS daemon on the node is not running or is recovering from an internal error.
- A node in the unknown state cannot be reached from the node on which the mmgetstate command was run.
- A node in the unresponsive state is reachable but the GPFS daemon on the node is not responding.
To follow up on investigating the state of a node, check if the node is functioning or has a network issue.
For more information, see mmgetstate command.
