BIG-IQ :: Add Hard Disk to VE

Ok, my Google-fu is lacking today. More coffee needed perhaps.

But for the life of me, I cannot figure out how to add another disk (virtual hard drive) to my BIG-IQ VE. I don't want to expand the current disk... which is what I am finding all of the articles pertain to (and which I already know how to do). My desire is to add another HD (via HD2) to the VE.

Any ideas on how to accomplish this?

root@(big-iq)(cfg-sync Standalone)(Active)(/Common)(tmos)# show sys hardware

              Media Type        HDD

  Name        HD2             
  Type        physical-disk   
  Model       Virtual disk    
  Parameters  --                --
              Manufacturer      VMware
              SerialNumber      VMware-sdb
              Size              95.00G
              Firmware Version  1.0
              Media Type        HDD

It seems that the VE can see the drive... but I can't install to it:

  root@(big-iq)(cfg-sync Standalone)(Active)(/Common)(tmos)# install sys software image BIG-IQ-6.1.0-0.0.1224.iso create-volume volume HD2.1
  root@(big-iq)(cfg-sync Standalone)(Active)(/Common)(tmos)#
  root@(big-iq)(cfg-sync Standalone)(Active)(/Common)(tmos)# show sys software status

  -----------------------------------------------------------------------------------
  Sys::Software Status
  Volume  Product  Version     Build  Active                                   Status

  HD1.1    BIG-IQ    6.0.0  0.0.1674     yes                                 complete
  HD2.1    BIG-IQ    6.1.0  0.0.1224      no  failed (Can't find requested disk HD2.)

I assume I am missing a step here.

Thanks in advance! -R

From Support:

I have an update for this. For an installation, you have to extend the existing volume. The additional disk is usable for data storage, but not for installation.

list /sys disk all-properties
sys disk logical-disk HD1 {
    mode mixed <------- this can be used to install
    size 97280
    vg-free 42160
    vg-in-use 53868
    vg-reserved 0
}
sys disk logical-disk HD2 {
    mode none <---------- This needs to be 'mixed'
    size 97280
    vg-free 0
    vg-in-use 0
    vg-reserved 19456
}

Basically HD2 exists only for some objects (datastore) but is not a valid OS install location.
