Hi Roberto,
The controller that is displaying detached has an amber and red light lit on it... doesn't look good. I had one drive that has been trying to rebuild since a week or so ago and it has only done 5%. There was also another drive in the logs that there were alerts about. I have tried to replace these drives with a vendor supplied equivalents... not my choice but they are NOT Hitachi drives... does Hitachi put specific firmware on their drives for environmental measurements and SMART etc?
Unfortunately I have pressed the little button on the faulty controller (LEDs were on before this) Which has now caused the Web interface to lose connection to the array.... and even putting the original drives back in they do not now spin up or become ready.
What is the correct power cycle procedure for this system should I need to do so please.The only thing I haven't done. I have all the manuals but it doesn't seem to give a process for that??
