Boot HP-UX 11.0 over the network

[roscher]

I have the following situation:

I have a BOOTP server on Linux
I have a TFTP server on Linux
I can boot a HP-UX 11.0 Kernel from my Linux server. But the kernel has no network card support and therfore the kernel can not
load a ramdisk (vmunix.fs) or is able to
mount his root file system over the network
(like Linux or other Unix systems can do
this ... 20 years old unix feature).

How can I compile a right HP-UX 11.0 kernel
for my purposes???

I have made a kernel with the following additional lines in the system file

ram
ufs
diskless_node 1
remote_nfs_swap 1
allocate_fs_swapmap 1

The kernel was made with the following command

mk_kernel -v -o /stand/vmunix.diskless -s /stand/system.diskless

Is there anybody out there, who want to realise a NFS diskless boot of HP-UX 11.0 ???

I know, that HP-UX 11.0 does no longer contain
NFS diskless, but the concept of a NFS based root file system is still available in the kernel and in the bootfiles (e.g. uxbootlf).

I have a B2000 HP-UX system. Must I go back
to HP-UX 10.20 to have NFS diskless, because
HP is too stupid to support and describe there
possible boot processes exactly ???

This is my answer to myself.

1. Modify /usr/conf/gen/config.sys

You must add -DDSKLESS to some definitions.

IDENT=-DDSKLESS} -D__ROSE__ ...
IDENT_TMP64=-DDSKLESS -D__TEMP64__
ROOT=/usr/conf/lib
IDENT_INT=-DDSKLESS -Dhp9000s800 ...
IDENT_KERN=-DDSKLESS -D_KERNEL -DKERNEL

2 Create /stand/vmunix.diskless

cp /stand/system /stand/system.diskless

3. Add the following lines at the end of
/stand/system.diskless

dskless_node 1
remote_nfs_swap 1
echo allocate_fs_swapmap 1

4. Copy a bootp.h from somewhere to
/usr/conf/h/bootp.h

5. Compile the kernel

mk_kernel -v -o /stand/vmunix.diskless
-s /stand/system.diskless

FINAL QUESTION

How can I make vmunix.fs ?????

This file is only available up to HPUX 10.20

[roscher]

Second incomplete answer to myself
I can not boot HPUX 11.0 over the network !!!

I have found the file vmunix.fs in the Patch
PHKL_20126.The new network boot has the following result

Boot
: lan(10/0/12/0;0)/stand/vmunix
7540736 + 885432 +1029648 start 0x246de8
lan(10/0/12/0;0)/stand/vmunix.fs Loaded

NOTICE: nfs3_link() File system was registered at index 4
NOTICE: autofs_link() File system was registered at index 6

Finally I have a kernel panic message.

How can I have the following message?

Starting NFS diskless client ....

Must I really go back to 10.20 ?????????

Hi,

The vmunix.fs you found is the one for 10.20.
So it won't work with an 11.0 kernel.


The error message means it doens't find the file symtab ( usually on /stand/dlkm) .
You may try to put the symtab generated with your kernel on your tftpdir


But the subject is interesting.....
