I have a T340 server that has a 440GB SSD drive as the boot drive and 4 12TB SAS drives.  There is nothing on any of them.

I went to LifeCycle and did a reset of all the options listed.  Currently it is at erasing the disks and states it will take 139 hours to complete.  

There is a warning not to turn off or CTRL+ALT+DEL until it is finished.  Since there is nothing on the drives, is it safe to reboot the system or am I stuck at waiting 5 days for it to complete?
