Issue: Server Boots into OS After ShredOS Disk Wipe

[Kyoomars]

Hi,

We plan to use ShredOS to wipe our server disks. Our long-term goal is to automate this process, but for now we are testing with the vanilla image to evaluate its effectiveness. We mount the ISO, and it successfully detects the disks on the server. We then start wiping with the default strategy (PRNG), and after approximately three hours, all disks appear to be wiped completely without any errors.

However, when we restart the server, it still boots into the existing OS (VMware ESXi) as before. The server has different types of diss. Could this be due to any limitations with the disk wiping process, or is there a recommended way to troubleshoot this issue?

Regards

I believe VMware ESXi it's a minimal hypervisor not an OS so it's possible it may not be installed on a disc like an OS. It would seem to be part of the firmware on the motherboard. So all the discs that ShredOS/nwipe said were successfully wiped will be deleted as per the logs. You can also check with the hexedit command in ShredOS (ALT F2 for the command prompt the hexedit /dev/nvme0n1 etc should you have any doubt. In the past I also used VMware to boot diskless systems via the network. So some form of network booting of VMware is also possible but certainly from a quick Google it would look like it's built in. Does the server specs mention a VMware hypervisor?

Maybe one of the guys that knows more about servers than I do can jump in.
