The bootsys command stores the original AUTO file line as a commented-out string in the AUTO file itself (using '#' as the comment char). Ignite-UX uses the value in _hp_boot_dev_path to reset the AUTO file in the LIF of that device if that disk is not used in the install.

On Itanium®-based systems the AUTO file is stored in the Extensible Firmware Interface (EFI) partition. Ignite-UX treats that AUTO file exactly the same way as the PA-RISC AUTO file stored in a boot LIF.

Do not have this variable set by any custom configuration file; its use is intended only for internal use within Ignite-UX.

The standard configuration files use _hp_boot_dev_path visible_if false to prevent this variable being visible or changeable using the Additional button in the Ignite-UX GUI.

_hp_primary_path

The _hp_primary_path string variable is set during the initial startup of Ignite-UX on the client. The variable is set to the system's primary boot path (as set in stable storage and read with setboot). If the system's primary boot path is incorrectly set to a non-existent device, then _hp_primary_path is set to the empty string ("").

Use this variable for reference only, or to set other variables. Do not have a configuration file assign it a value. Ignite-UX sets the value.

_hp_primary_partition_size

The _hp_primary_partition_size variable controls the size of the HP-UX partition on an EFI boot disk on HP Itanium®-based systems. Normally, the value of this variable is calculated as the remainder of the disk being installed to after the other partition sizes have been subtracted. For more information regarding the EFI and HPSP partitions, see "_hp_efi_partition_size" and "_hp_service_partition_size".

Typically, there is no reason to set the _hp_primary_partition_size variable in a custom configuration. If you do set this variable and the size is too large, it is automatically reduced; if set too low, part of the boot disk remains unused.

_hp_efi_partition_size

The _hp_efi_partition_size integer variable is set by the Ignite-UX GUI to indicate the size of the HP-UX Extensible Firmware Interface (EFI) boot partition on Itanium®-based systems. This disk partition holds loader software and other utilities used to boot the HP-UX operating system. This value defaults to a size that allows some space for additional boot partition content in future HP-UX releases. This variable is adjusted to the minimum EFI boot partition size if set to zero or a value less than the minimum. This variable is supported starting with HP-UX 11.23 and is only supported on Itanium®-based systems.

This variable sets the size of the EFI partition located on bootable disks on Itanium®-based systems. The minimum size is 150MB (default size 500MB) currently.

This variable can affect recoveries. For example, if there is no free space left on the boot disk and an Ignite-UX version is released that increases the size of the EFI partition, the recovery or installation requires manual intervention if the EFI partition size minimum is increased because of lack of disk space.
