Question :
The documentation is unclear on if the firstdisk=disk-type1[,disk-type2]... parameter of the install command is a filter or only a ordering of what disk to install ESXi on. E.g., when using --firstdisk=local will this cause ESXi to be ONLY installed on local disks and NEVER on remote disks? or does this only set "local" disks to be considered before all other disks types but, if no local disks are found, will eventually install ESXi on a e.g. remote disk type anyways. This may seem like a little detail but it makes a huge difference. Many LUNs have been lost this way...
