The kernel discovery tool used by SAM failed

yyghp — Wed, 21 Apr 2004 10:26:30 GMT

When I took a look at the "Kernel Configuration" with SAM, I saw 4 options:
Configurable Parameters,
Drivers,
Dump Devices,
Subsystems
However, I couldn't get into any of them, I got an error message box when I chose one of them:

Internal error: The kernel discovery tool used by SAM failed.
Kernel changes cannot be made by SAM. The standard error output of
the command is shown below:

getkinfo: Syntax error in system file.
Incorrect swap statement(s): swap

The swap statement shown above is not valid for one of the following reasons: There are too many swap statements in the system file (at most one is allowed); there are too few parameters after the "swap" keyword (must be at least one); an invalid hard partition number is given (must be an integer between 0 and 15). Refer to the SAM logfile for more information.

getkinfo: Unable to read the kernel file "/stand/vmunix".

Why? and how to solve this problem ?
Thanks !

Look in /stand there should be a file called
vmunix. If not, restore it immediately .
If you dont have a backup try using vmunix.prev
cp vmunix.prev vmunix

Good luck

It seemed the kenel hadn't been changed since last June...
Any risk to replace vmunix with vmunix.prev ?

Thanks!

Try to check the content of /stand/system

Is ther a line with a swap entry.
(the maxswapchunks line id OK)

if so :
copy /stand/system to i.e. /tmp and remove the corrspondig line(s) using vi.

retry the sam again.

If it does not work, recover /stand/system from the copy, and ask for other help :)

I'm not sure it will help, but there's certainly no risk in using vmunix.prev. Just move the current one aside (mv /stand/vmunix /stand/vmunix.old), then rename the previous one (mv /stand/vmunix.prev /stand/vmunix). Do the same thing with the system files (mv /stand/system /stand/system.old and mv /stand/system.prev /stand/system).

Hi I would check the existence of /stand/system & /stand/vmunix. if not present I would try to create from running system_prep -v -s /stand/system and mk_kernel from the current settings .

Hi,

Try this link,

http://www2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000063248227

The itrc doc id is 2200228339.

Check the size of the files
/usr/conf/lib/libhp-ux.a
/usr/conf/lib/libstream.a
from another system and if possible take a backup of these two files on the system you are having problem and copy from another working system. Make sure the Two OS's are same 11.0/10.20 ..

Then try the kernel configuration again.

Hope this helps.

Hi Juergen,

in /stand/system, only the line "maxswapchunks" contains "swap".

hi sinhass,

-rw-r--r-- 1 root sys 1572 Jun 24 2003 system
drwxr-xr-x 2 root sys 1024 Jun 19 2003 system.d
-rw-r--r-- 1 root sys 1572 Jun 24 2003 system.prev
-rwxr-xr-x 1 root sys 26750202 Jun 24 2003 vmunix
-rwxr-xr-x 1 root sys 26753994 Jun 24 2003 vmunix.prev

system & vmunix are there...

Hi Sanjay,

same size, both.

Hi,

I feel that I would rename the system file and try to catch current configuration with system_prep command. Also I would try to build a new kernel with cutrrently running systems before doing anything.
