Create a new kernal screen appear

[Macho_2]

I'm using sam and go to Disk and file system and under Disk Devices, I'm checking unused disk.After that,when I exit the Disk Devices menu there are Create a New Kernal screen appear and I found out there are 3 kernal parameter has been change.Then I try to cancel all the kernel parameter changes and exit the manu but still after that If I used back the Disk Devices menu under SAM,the Create a New Kernal screen appear again.
For information there are no new patches has been installed and no new driver has been attach to the server and also nobody change the kernal parameter.
What should I do ?

Hi,

It seems that some kernal paramaters have been changed/patch installation has been done but new kernal has not been created.

If you work on disk and file system in SAM, it dosent affect kernal.

Check if somone has changed the kernal parameter but has not updated the kernal...
If you are changing the kernal it is good practice to have a copy of running kernal so in case if new kernal doesnt work you can always revert back.

Cheers!!!

Can you list out what are kernel parameters ?

are you finding any error at /var/adm/syslog/syslog.log ?

Is there any file found under # /stand/build directory if so then somebody has generated the new kernel and reboot is left

Check /var/adm/sam/samlog. you canuser samlog_viewer to check samlog.

Is there any file found under # /stand/build directory if so then somebody has generated the new kernel and reboot is left

I forget to add another kernel parameter that change :-
It was nswapdev

Hi,

Posibally you have tried to add another swap. If you do so without altering this parameter then SAM will automatically prompt you to change this as without changing this your new swap will not be active. Find out from output of "kmtune -q nswapdev" wheather both planned & current value are same or not.

If both are same then posibally you need to recreate new kernel & if yoi do not want to change the new kernel then go o Kernel configuration in sam & chnage planned value of this parameter to the same as current value. After that posibally it will go away.

Another possibality is that you have added swap & Cancel kernel changes after that.

Hust a thought.
