HP StoreOnce Backup - Manual (Page 185)

Should a node or a couplet fail to successfully power on after a node experienced an unclean
power off, power off both nodes in the couplet (using the nodes' power buttons, if necessary).
Power on one node and then power on the other node in the couplet.
Rebooting the system
•
system reboot : This gracefully reboots the cluster by shutting down all services and
StoreOnce service sets before powering down the servers. This means on reboot the
deduplication stores will start up from a clean state.
•
hardware reboot nodeX : This uses the iLO port to reboot the server, which does not allow
StoreOnce service sets to reboot gracefully. This results in deduplication stores shutting down
in an unclean state and requiring integrity checking (an automatic process) on reboot.
The following sequence is recommended if you wish to reboot a node in a controlled way. It fails
over the service set before rebooting the node.
hardware enable failover
hardware failover nodeX
hardware reboot nodeX
Once nodeX has completed rebooted:
hardware failback nodeX
Networking problems
The network configuration is probably the most complex aspect of installation and is described in
detail in the Planning Guide that you received prior to installation. Please read that guide for a
description of the HP Storeonce Backup system's implementation of physical IP and Virtual Interface
(VIF) addresses.
This section provides important guidelines if you need to troubleshoot the network after installation.
Internal network switches
The HP StoreOnce Backup system has two internal network switches in each rack and the cabling
required to connect to these switches is pre-installed. The cabling to each node is shown below.
IMPORTANT: You should NEVER unplug this cabling. The ports illustrated are reserved for use
with the internal network switch and cannot be used to connect to your network. Also, you should
NEVER connect your external network to the switches at the top of the racks.
