swverify \*

You may have a patching problem.

Please verify that PHKL_18453 is installed and has only been installed once.

OS backup is best done with make_tape_recovery to tape or make_net_recovery to an nfs share on an Ignite server.

Hello.

It full describe of my problem:

-------------------------------------------

mk_kernel fails to create /stand/build/vmunix_test

PROBLEM

When trying to create a new kernel manually on HP-UX 11.00 the mk_kernel command fails to create vmunix_test in the /stand/build directory.
No errors are reported. The exit code of mk_kernel is zero and it completes very fast and returns to a prompt:

# cd /stand/build
# /usr/lbin/sysadm/system_prep -v -s system
NOTE: The template file has been extracted from "/stand/vmunix"
It has been placed in "system" where it will be used
to build a new kernel.
# /usr/sbin/mk_kernel -s /stand/build/system #

Usually the output looks like this:

# /usr/sbin/mk_kernel -s /stand/build/system Generating module: krm...
/usr/bin/mkdir -p /stand/build
Compiling conf.c...
Loading the kernel...
Generating kernel symbol table...
#

None of the above messages from mk_kernel are being reported.
Why does mk_kernel fail ?

CONFIGURATION

HP-UX 11.X

RESOLUTION

The mk_kernel command calls config. This is the command which fails in the mk_kernel script:

# sh -x mk_kernel -s /stand/build/system ...
+ config -m /usr/conf/master.d /stand/build/system cmd_result=0 [[ 0 -ne
+ 0 ]] [[ -n ]] [[ -n ]] exit 0

The config command would usually report its progress on the command line:
Generating module: krm...
Compiling conf.c...
Loading the kernel...
Generating kernel symbol table...

but none of the above messages are reported. config calls the make command in turn (see man config(1M)):

# type make
make is a tracked alias for /usr/bin/make # ll /usr/bin/make
lr-xr-xr-t 1 root sys 17 Jun 26 2001 /usr/bin/make
-> /usr/ccs/bin/make

It turned out that /usr/ccs/bin/make was a zero size file. All files in the /usr/ccs/bin directory were zero size.

These files need to be restored from backup in order for mk_kernel to succeed.

--------------------------------------------

If somebody can help me and can send me needed backup that will be very good :-)

BR,

Only re-installation of HP-UX or restore failed files from backup copies can help. It official answer of HP support.
