• The power on button on each server to trigger a cold boot and automatically power on.
• StoreOnce CLI commands to power on a node remotely. (This method requires a server node that
is running.) For example, if a node was powered off using CLI commands, power it up again using
the following CLI command:
hardware powerup nodeX
2.
After a successful power on, ensure that failover is enabled.
• To check the status of failover:
hardware show node status
• To enable failover if it is off:
system enable failover
3.
Once failover is enabled, check that no service sets have failed over during any reboot sequence:
• To check the status of the service sets:
hardware show node status
NOTE:
You can also use the GUI to check the status. Look at the StoreOnce System page of the
GUI and check the failover status of the service set.
• To fail them back:
system failback setX
NOTE:
You can also use the GUI to failback a node. Locate the node in the Hardware pages of the
GUI and click
Failback this server
.
If power on is unsuccessful
IMPORTANT:
A previous unclean shutdown will lead to integrity checking of the storage and your user data.
Depending upon the amount of data stored on the couplet, this process can take several hours. Be
patient to see whether the Service Set will come online without further intervention or reboot.
If node or a couplet fails to successfully power on after a node experienced an unclean power off, power
off both nodes in the couplet (using the power buttons on the nodes if necessary). Power on one node
and then power on the other node in the couplet.
Powering off using the StoreOnce CLI
Various commands exist to shut down a node or a cluster. Use the correct command to perform the task
required. More details can be found in the
StoreOnce System CLI Reference Guide
.
NOTE:
A power off command only powers off the server component. If the maintenance activity requires
the disk enclosure or internal network switch to be powered off, power them off manually.
