I'm looking for a little more information on wiping drives throught the lifecycle controller. I have some R740s and R640s I need to wipe completely.

What wiping method does it use to wipe the drives if it can't use the cryptographic method?

If a drive fails to wipe for some reason, how do I know it? When I booted one up and began the reuposing process, I briefly saw on screen that it had an issue with one of the drives. However, it showed up so briefly that I could read it. Then it got into the screen where it lists all of the processes that it will go through, such as wiping the logs and defaulting the configuration.
