    Default Boot media mirroring

    Tried to configure boot media mirroring for JovianDSS up.19 in VMWare virtual environment and found it can not be configured.

    - The VM configuration has 2 'local' disks to configure: #1 is already bootable and #15 to be added as a mirror. Disk #1 is 16GB, disk #15 tried 16Gb and 18GB sizes.

    - The add mirror media dialog displays nothing to add.

    - Rescan and reboot do not make effect.
    - The configured media reporting single disk with odd size, which is strange.

    My questions are:
    - Is it mandatory for the mirror media to be listed before media, included in pools?
    - Is it possible the issue found is coupled with virtual environment?
    - Is it possible the issue found depends of product activation?
    - What else might be check before trying to add media to mirror?

    This issue is most likely related to VMWare ESXi settings:

    VMWare's ESX GUI > machine properties > advanced > general > configuration parameters > add row > disk.enableUUID = "TRUE"

    or directly via VMX config file on VMFS / ESXi server:

    *.vmx:

    disk.enableUUID = "TRUE"

    Please stop affected machine beforehand.
