This is an ANCIENT feature of the OS! Back in the good ol' S/38 days we had a system that didn't have the landing gear down. If you stood at the console and leaned forward, the system would roll. And everything would come to a screeching halt! Roll the system back, and everything revived.

Seems one of the disk attachment cables wasn't locked down, and rolling the system would unplug/plug the cable. OS just waited until the disk was back. I think we did get a message on the lights to look up.

This kept up until the plug unplugged one day and didn't plug itself back in. The CE was able to lock it back in place.

Wellllllllll it didn't truly Hibernate the partitions they actually just
stood frozen until their disks came back!! This has been around for a
while. I've had customers lose power to towers or turn off power to disk
units and the O/S simply sits there until the disks return and then off
it goes!

Definitely a GOOD thing!
