Dell PowerScale OneFS User Manual

Administrator action
If the Cluster Status page in the OneFS web administration interface indicates that a node is down, complete the following
steps.
1. Determine whether the node is turned on. Visually inspect the node to verify that the power light is on.
2. If the node is turned off, attempt to turn the node on.
● If the node turns on, view the Cluster Status page to determine whether the node has rejoined the cluster. If the node
does not rejoin the cluster, proceed to step 3.
● If the node rejoins the cluster, and the cluster is operational, the event will cancel.
● If the node does not turn on, make sure that any circuit breakers in the power path are closed and that the power outlets
for the node are active. If the node is not receiving power, resolve the power supply issue. If the node is receiving power,
contact Technical Support.
3. If the node is on but did not rejoin the cluster, attempt to establish remote access through a secure shell (SSH) session. If
the SSH session fails, attempt to establish remote access through the serial console.
4. If neither the SSH session nor the serial console is responsive, press CTRL+T in the SSH session or in the serial console.
● If pressing CTRL+T produces output, record the output, and then contact Technical Support for failure analysis.
● If the node is unresponsive, turn the power off and then on again.
