You can specify the following options to customize booting from a storage device.

inst.nompath

Disables support for multipath devices. Use this option only if your system has a false-positive that incorrectly identifies a normal block device as a multipath device.

Warning

Use this option with caution. Do not use this option with multipath hardware. Using this option to install to a single path of a multipath device is not supported.

inst.gpt

Prefer creation of GPT disk labels. This option is deprecated and will be removed in future releases. Use inst.disklabel=gpt instead.

inst.disklabel=

Prefer creation of the specified disk label type. Specify gpt to prefer creation of GPT disk labels (default). Specify mbr to prefer creation of MBR disk labels if supported.

inst.wait_for_disks=

Use the inst.wait_for_disks= option to specify the number of seconds installation program to wait for disk devices to appear at the beginning of the installation. Use this option when you use the OEMDRV-labeled device to automatically load the Kickstart file or the kernel drivers but the device takes a longer time to appear during the boot process. By default, the installation program waits for 5 seconds. Use 0 seconds to minimize the delay.

inst.nonibftiscsiboot

The inst.nonibftiscsiboot option enables placement of the boot loader on iSCSI devices that are not configured through the iSCSI boot firmware table (iBFT).
