--firstdisk= disk-type1, [disk-type2,...] --ignoressd --overwritevsan --overwritevmfs --preservevmfs --novmfsondisk Chapter 7 Installing ESXi n vmkLUN UID: --disk=vmkLUN_UID For accepted disk name formats, see "Disk Device Names," on page 154. Partitions the first eligible disk found. By default, the eligible disks are set to the following order: 1 Locally attached storage (local) 2 Network storage (remote) 3 USB disks (usb) You can change the order of the disks by using a comma separated list appended to the argument. If you provide a filter list, the default settings are overridden. You can combine filters to specify a particular disk, including esx for the first disk with ESX installed on it, model and vendor information, or the name of the vmkernel device driver. For example, to prefer a disk with the model name ST3120814A and any disk that uses the mptsas driver rather than a normal local disk, the argument is --firstdisk=ST3120814A,mptsas,local. Excludes solid-state disks (S--firstdiskSDs) from eligibility for partitioning. This option can be used with the install command and the --firstdisk option. This option takes precedence over the --firstdisk option. This option is invalid with the --drive or --disk options and with the upgrade and installorupgrade commands. See the vSphere Storage documentation for more information about preventing SSD formatting during auto-partitioning. You must use the --overwritevsan option when you install ESXi on a disk, either SSD or HDD (magnetic), that is in a Virtual SAN disk group. If you use this option and there is no Virtual SAN partition on the selected disk, the installation will fail. When you install ESXi on a disk that is in Virtual SAN disk group, the result depends on the disk you select: n If you select an SSD, the SSD and all underlying HDDs in the same disk group will be wiped. n If you select an HDD, and the disk group size is greater than two, only the selected HDD will be wiped. n If you select an HDD disk, and the disk group size is two or less, the SSD and the selected HDD will be wiped. For more information about managing Virtual SAN disk groups, see the vSphere Storage documentation. Required to overwrite an existing VMFS datastore on the disk before installation. Preserves an existing VMFS datastore on the disk during installation. Prevents a VMFS partition from being created on this disk. Must be used with --overwritevmfs if a VMFS partition already exists on the disk. VMware, Inc. 147
