HP StoreOnce Backup - Manual (Page 184)

Powering off using the StoreOnce CLI
Various commands exist to shutdown a node or a cluster. Please use the correct command to
perform the task you require. More details can be found in the HP StoreOnce Backup system CLI
Reference Guide.
•
system shutdown : This gracefully shuts down the cluster by shutting down all services and
StoreOnce service sets before powering down the servers. This means when you power back
up, the deduplication stores will start up from a clean state. Servers will be in the off state,
and will require powering on via the power button or CLI.
•
hardware poweroff nodeX : This uses the iLO port to turn off the server, which does not
allow StoreOnce service sets to shutdown gracefully. This results in deduplication stores shutting
down in an unclean state and requiring integrity checking (an automatic process) on the next
power on. To avoid this condition, the service set on a given node should be failed over to
the backup node using the hardware failover nodeX command prior to powering down
the node.
Powering on
1. Power on the server using either:
•
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. For example, if a node has
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:
hardware enable failover
3. If failover was 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 HP StoreOnce page
of the GUI and check the Failover status of the service set.
•
To fail them back:
hardware failback nodeX
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 can take several
hours. Please be patient to wait to see whether the Service Set will come on line without further
intervention or reboot
