/stand filesystem

Why does HP recommend to mount /stand as HFS file system only ?

The HP-UX kernel is unable to read JFS metadata structures. As a result, the /stand File System must be HFS.

Hi,

The ISL, initial System Loader, is not that advanced, it only understands HFS. In /stand the UNIX kernel is found and loaded. This kernel is more advanced so all the other filesystems do not have to be HFS.

HTH,

Hi again,

Here is some additional information:

HP-UX IPF Bootloader

HP-UX 11i Version 1.5 (B.11.20) IPF bootloader allows you to locate and boot the desired HP-UX kernel. Because the HP-UX IPF bootloader can boot from the VxFS file system, it is not necessary for /stand to be an HFS file system.
When an Itanium-based system boots, you are placed in either the EFI (Extensible Firmware Interface) boot manager or the EFI shell. The HP-UX IPF bootloader is a native EFI application that can be launched from either application. To boot any machine with HP-UX, the HP-UX IPF bootloader must be placed in the EFI partition of the boot disk.

IPF Bootloader Compatibility

The HP-UX IPF bootloader is not compatible with the HP-UX PA bootloader. It can not boot a PA kernel and can not be used in a PA machine.

(SO this does not work with an PA-RISC server)
