multiple Drives have been spun down due to exceeding the acceptable temperature range. If the system
shuts down due to a pending TOC quorum loss from the spin down of too many Drives, power remains on
for the nodes, Drives, and Drive Enclosures.
For overheated Controller Nodes, a single Controller Node is shut down if one of its sensors reports a
critical temperature.
For overheated Drives, the Drives are spun down individually. With multiple overheated Drives being spun
down, there is the danger of a TOC quorum loss, so the system executes a controlled shutdown. For a
controlled shutdown, the hardware remains powered on and the Controller Nodes reboot when the
ambient temperature has reduced and remains in the acceptable range for at least 30 minutes.
