We had a power outage who's durration exceeded the UPS battery capasity and the device lost power. I had to touch the power button to get this up and would rather it go in it's own. How can I configure the R2000 to automaticly start up when the power returns?

I newer use Last State or AlwaysOn when we speak about Storage devices itself. Power can be flapping and Array should be always power on UPS. But when we must power off Arrays then power on we do on one of scenario:

1) UPS with selective groups with Management on PDU - automatical or manual power on after 15minutes stable power OR 25% of UPS.
2) Manual via WakeOnLan (Activate WOL by CLI: net -a mod -f ipv4 -s "wol=enable" )

Hi CW,

You have to log in to the CLI and use the "ctrl -v" command to check the state of the "restore ac mode".

The values are 'alwayson' , 'alwaysoff', and 'laststate'.

To set it so that the unit will always start at power restore:

ctrl -a mod -s "restoreacmode=alwayson"

Cheers, Richard
