How long should it take for firmware update? Firmware update failing

[dannieboiz]

Tried to update from Front view automatically but it keeps on failing. Going from 6.5.1 to 6.5.2

Just did a manual update from 6.5.1 to 6.6 it uploaded and asked to reboot. It's been 10 minutes but I'm still not seeing it on Raidar. How long should I wait before power cycling it manually?

I just upgraded from 6.5.2 to 6.6.0 and it went fast.  It didn't take much longer then a normal bootup.  So pretty quickly.  This was on my upgraded ReadyNAS 516.   It sure didn't take no 10+ minutes.  I'd wait for at least 30 minutes before doing something drastic like a power cycle.
