Stale partitions are listed on creating a virtual disk for Linux

Description:
When a virtual disk is created using physical disks that were earlier used for creating Linux virtual disk, some Linux partitions are present during operating system installation.
Solution
When you create or delete a virtual disk, only the superblock metadata is modified. The partition table of the virtual disk that is stored at logical LBA-0 is not modified. Hence, when you re-create a virtual disk, the previous partitions are still listed.
  • During operating system installation, these partitions can be deleted using the operating system installer.
  • To not list the partitions, if supported you can perform cryptographic erase of the physical disk and then create a virtual disk from the HII.
    NOTE:Performing cryptographic erase deletes all the data on the physical disks.
NOTE:In the Non RAID mode, if the NVMe disks (that were earlier used to create VDs) are reused without deleting the metadata, the Linux Installer still detects the VDs.
