HP StoreOnce 2700, 4500, 4700 and 4900 Backup System User Guide

Rebooting the system
• system reboot: This gracefully reboots the appliance by shutting down all services before
powering down the server. This means on reboot the deduplication stores will start up from a
clean state.
• hardware reboot: 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.
Power On/Off Problems
HP StoreOnce Backup system shuts down automatically
If the HP StoreOnce Backup system has found a problem with the internal hardware which requires
the device to shutdown to avoid further hardware problems, the System Health LED on the front
panel will probably be flashing RED. Reboot and watch for errors on boot up.
HP StoreOnce Backup system does not boot up correctly
Check the Power LED on the front panel.
If the Power LED is OFF:
• Check power is connected to the HP StoreOnce Backup system and is on.
• The PSU may be faulty.
If the Power LED is AMBER:
• Power on the HP StoreOnce Backup system using the Power button.
• If it shuts down again, see (page 175).
If the Power LED is GREEN but you cannot log in. Reboot and check for hardware errors as the
HP StoreOnce Backup system device boots up.
HP StoreOnce Backup system System Health LED is flashing RED
One of the two power supplies is faulty or not connected to power at power on time, causing a
warning condition. Check the LED on the PSU to ensure it is not faulty (it should be green). Ensure
both power supplies are connected and reboot to clear this LED. The HP StoreOnce Backup system
will work satisfactorily with one power supply, but without any redundancy. It is recommended to
power on the second power supply or replace the power supply as soon as possible.
Cannot authenticate an iSCSI session
CHAP authentication is used within HP StoreOnce Backup systems that support iSCSI. For details
of the settings on the Microsoft iSCSI initiator and the HP StoreOnce Management Console, see
also the HP StoreOnce Backup system Installation and Configuration Guide.
If the HP StoreOnce Backup system runs out of disk space
A warning message is generated when the HP StoreOnce Backup system reaches 90% capacity.
If you have a StoreOnce 4900 Backup system, you can purchase and install Capacity Expansion
kits for the disk enclosure; the 44TB expansion kit provides 11 4TB-disks; the 60TB expansion kit
provides an additional disk enclosure.
If you have the older, 12–disk array base units, you can purchase and install a Capacity Upgrade
Kit to expand your capacity. This is an expansion shelf containing 12 2TB-disks. If you have done
so and are still out of space, make sure that you have fully expanded the storage capacity. (The
HP StoreOnce 2700 and 26xx Series do not support connection of a Capacity Upgrade Kit.) See
the documentation provided with the Capacity Expansion Kit for detailed instructions.
