A customer called me because there were an allert in his BLade S, so, after a check I saw two disks in PFA state.
As normal i called IBM (ops Lenovo!) to activate the on site support.. some hours later the Lenovo engeneer is arrived to replace the PFA’s drives.
In this case, I tooke some screenshots becouse it was interesting the metod becouse, he used the copy-back operation that means the use of an empty drive to switch from one drive in PFA an a ne one, in our case the hotsphare drives (it was changed from hot-s to free).
Our body of evidence, an old Blade-S.
