Thanks to the "Secure Erase Unit" command, deleting SSDs only takes a minute. This command will also display the estimated time to complete. Verify that "Sanitize Erase" is supported.

Either use the HPE-Customized bundle or install it from the HPE Vibs Depot. Secure Erase can be used from the ESXi console with ssacli when the HPUtil bundle is installed. More information about HP Secure Erase can be found here. The command tells the SSD to apply a voltage spike to all available NAND cells and thus resetting every available block in one operation. To overcome this issue, the “Security Erase Unit” command has been introduced. This method is slow and not sufficient for SSDs because they are typically overprovisioned (by having more cells as exposed) which makes it impossible to erase all data. Magnetic HDDs can be erased by overwriting every sector. It's important to know that erasing SSDs and HDDs isn't the same. HPE Gen 8 or later Raid Controllers have a Secure Erase feature that allows Industry-standard disk sanitation. The output is omitted the * indicates that there a duplicate line, which means all data on the drive is zero. If you want to verify that there is no data left on the device, use the od command. The conv=notrunc option is required or the commandf fails with the following error message: # dd if=/dev/zero of=/dev/disks/t10.NVMe_Samsung_SSD_960_EVOĭd: can't open '/dev/disks/t10.NVMe_Samsung_SSD_960_EVO': Function not implemented # dd if=/dev/zero of=/dev/disks/t10.NVMe_Samsung_SSD_960_EVO conv=notrunc In ESXi, this can be done from the console. If you want to sell disks or make sure that all data is deleted, you have to overwrite all blocks. However, data is not overwritten and can be restored. This function deletes all partitions to reuse disks with vSAN for example. Since a couple of versions, vSphere comes with an erase function in the GUI.
