BIG-IQ :: Add Hard Disk to VE

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.
