Installation and Upgrade Script Commands

To determine which disk to install or upgrade ESXi on, the installation script requires one of the following commands: install, upgrade, or installorupgrade. The install command creates the default partitions, including a VMFS datastore that occupies all available space after the other partitions are created.

accepteula or vmaccepteula (Required)

Accepts the ESXi license agreement.

clearpart (Optional)

Clears any existing partitions on the disk. Requires the install command to be specified. Carefully edit the clearpart command in your existing scripts.

--drives=

Remove partitions on the specified drives.

--alldrives

Ignores the --drives= requirement and allows clearing of partitions on every drive.

--ignoredrives=

Removes partitions on all drives except those specified. Required unless the --drives= or --alldrives flag is specified.

--overwritevmfs

Allows overwriting of VMFS partitions on the specified drives. By default, overwriting VMFS partitions is not allowed.

--firstdisk=

disk-type1

[disk-type2,...]

Partitions the first eligible disk found. By default, the eligible disks are set to the following order:

Locally attached storage (local)
Network storage (remote)
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 ESXi 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. You can use localesx for local storage that contains ESXi image or remoteesx for remote storage that contains ESXi image.

dryrun (Optional)

Parses and checks the installation script. Does not perform the installation.

install

Specifies that this is a fresh installation. Either the install, upgrade, or installorupgrade command is required to determine which disk to install or upgrade ESXi on.

--disk= or --drive=

Specifies the disk to partition. In the command --disk=diskname, the diskname can be a disk name or a full disk filesystem path in ESXi, for example:

Disk name: --disk=naa.6d09466044143600247aee55ca2a6405 or
Device path: --disk=/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0

For accepted disk name formats, see Disk Device Names.

--firstdisk=

disk-type1,

[ disk-type2,...]

Partitions the first eligible disk found. By default, the eligible disks are set to the following order:

Locally attached storage (local)
Network storage (remote)
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. You can use localesx for local storage that contains ESXi image or remoteesx for remote storage that contains ESXi image.

--ignoressd

Excludes solid-state disks 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.

--overwritevsan

You must use the --overwritevsan option when you install ESXi on a disk, either SSD or HDD (magnetic), that is in a vSAN disk group. If you use this option and no vSAN partition is on the selected disk, the installation fails. When you install ESXi on a disk that is in vSAN disk group, the result depends on the disk that you select:

If you select an SSD, the SSD and all underlying HDDs in the same disk group is wiped.
If you select an HDD, and the disk group size is greater than two, only the selected HDD is wiped.
If you select an HDD disk, and the disk group size is two or less, the SSD and the selected HDD is wiped.

For more information about managing vSAN disk groups, see the vSphere Storage documentation.

--overwritevmfs

Required to overwrite an existing VMFS datastore on the disk before installation.

--preservevmfs

Preserves an existing VMFS datastore on the disk during installation.

--novmfsondisk

Prevents a VMFS partition from being created on this disk. Must be used with --overwritevmfs if a VMFS partition exists on the disk.

installorupgrade

Either the install, upgrade, or installorupgrade command is required to determine which disk to install or upgrade ESXi on.

--disk= or --drive=

Specifies the disk to partition. In the command --disk=diskname, the diskname can be a disk name or a full disk filesystem path in ESXi, for example:

Disk name: --disk=naa.6d09466044143600247aee55ca2a6405 or
Device path: --disk=/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0

--overwritevmfs

You can use localesx for local storage that contains ESXi image or remoteesx for remote storage that contains ESXi image.

%include or include (Optional)

Specifies another installation script to parse. This command is treated similarly to a multiline command, but takes only one argument.

filename: For example: %include part.cfg

%pre (Optional)

Specifies a script to run before the kickstart configuration is evaluated. For example, you can use it to generate files for the kickstart file to include.

--interpreter
=[python|busybox]: Specifies an interpreter to use. The default is busybox.

%post (Optional)

Runs the specified script after package installation is complete. If you specify multiple %post sections, they run in the order that they appear in the installation script.

--interpreter
=[python|busybox]: Specifies an interpreter to use. The default is busybox.
--timeout=secs: Specifies a timeout for running the script. If the script is not finished when the timeout expires, the script is forcefully stopped.
--ignorefailure
=[true|false]: If true, the installation is considered a success even if the %post script stops with an error.

%firstboot

Creates an init script that runs only during the first boot. The script has no effect on subsequent boots. If multiple %firstboot sections are specified, they run in the order that they appear in the kickstart file.

Note: You cannot check the semantics of %firstboot scripts until the system is booting for the first time. A %firstboot script might contain potentially catastrophic errors that are not exposed until after the installation is complete.

Important: The %firstboot script does not run, if secure boot is enabled on the ESXi host.

--interpreter
=[python|busybox]: Specifies an interpreter to use. The default is busybox.

Note: You cannot check the semantics of the %firstboot script until the system boots for the first time. If the script contains errors, they are not exposed until after the installation is complete.
