Array power settings

We have rebuilt two drives in the array following a failure and now when the host powers down or goes to sleep, so does the array. This did not happen before the rebuild. This means that crucial data cannot be backed up out of work hours.

I’ve read through the manual and there is a few lines on power modes but nothing on how to change power settings.

Has anyone had this problem and found a resolution please?

All of the Studio products since release have functioned in that way. If the computer is off or asleep it will also cause the unit to turn off. This is due to the requirement that it have an active Thunderbolt connection to the computer in order to remain on.

You can allow the display to sleep on the system but you need to keep the computer active at all times in order to maintain this device.
