Filesystem

Zafar A. Mohammed — Tue, 31 Jul 2001 15:14:10 GMT

For HP-UX 11.00 or later::
I know / (root) filesystem can HFS or VxFS; but what about /stand. To my understanding it should be HFS becuase it has the Kernel and all bootable parameters.
Can anyone have any inputs.
Thanks

Stand must be HFS because of the kernel loading requirements.
The kernel is loaded before the / filesystem is mounted.

Later,
Bill

Hi
/stand still need to be HFS.

Hi:

The /stand filesystem must be HFS in order for the loader to find the kernel.

Hi (again):

If you are running HP-UX 11.20 (11i verion 1.5), then you *can* boot from a VxFS /stand filesystem. That is, /stand *can* be VxFS for this release. HP-UX 11.20 is for the new Itanium processors.

Yes, it is must be HFS although other file systems can be HFS or VxFS because kernel locates there.

HI,

With the exception of the new Itanium release, /stand must be HFS because that is all the boot firmware understands. To allow booting from VxFS, HP would have to the firmware on many, many old machines.

Some of the other unix versions even had a grater restriction in that the bootfilesystem
could not even have directories. /stand was required to be a flat filesystem.
