Hi All,

In server there are three for vmunix file in /stand file system.

How can we check which current kernel the server is using it.

To tell from which kernel booting was performed, do the following:
Using adb(1) :

o echo boot_string/S | adb /stand/vmunix /dev/kmem
Using dmesg(1M) :
If dmesg(1M) works, booting was performed from /stand/vmunix .
If dmesg(1M) does not work, run it against each kernel in /stand , until dmesg works.
When dmesg works, the kernel from which booting was performed is found. For example:

# dmesg

May 17 08:16
Magic number wrong (namelist mismatch?)
The previously mentioned example is the equivalent of:

# dmesg /dev/kmem /stand/vmunix

May 17 08:19
Magic number wrong (namelist mismatch?)

For 11.23 and 11.31:
It is much easier.
The following is a list of directories and their meanings that now exist with B.11.23:

Currently running kernel: /stand/current/
Copy of the current config prior to changes: /stand/backup/
Kernel config originally installed with OS /stand/last_install/
Link to the config to be used at the next boot: /stand/nextboot/
Automatically created after any crash dump: /stand/crashconfig/
There are also two special files in /stand:
/stand/vmunix is a hard link to /stand/current/vmunix
/stand/system is a soft link to /stand/nextboot/system

Thanks for replying to all of you,
But still i am not able to get it,

I am not able to decide from which current kernel the server is running.

Hi,

You can use the below command to know the result

dmesg | grep boot
or
dmesg | grep -i vmunix

Hi,

You can use kconfig with -S parameter.

See the man kconfig

-S
kconfig will display all settings of the currently running configuration that are not at their default value. In other words, it will execute

kcmodule -S

kctune -S

(If any additional kernel configuration data become available in future HP-UX releases, settings of them will be included as well.) Not valid in combination with any other flags.

hope this help.

When the 2 linkstamp lines are matching, then it is the booted kernel.
