Kernel configurable parameter remain unchanged after process new kernel

Dear ALL:

We are trying to modify some kernel parameters as given in below table but the problem is:â After modifying & process new kernel through SAM, Kernel configurable parameter remains unchangedâ . We also reboot the server but no works. I have attached a file which is an example what we have done through SAM for the below parameters.


Beside this â lanscanâ command didnâ t show any output & during taking nickel it shows some error which is attached with this mail. If you need more information, please let me know


Note: Model of this server is RP3440 & OS version B.11.11

Dear Asif

"lanscan" command output shows nothing even no error.

Re: Kernel configurable parameter remain unchanged after process new kernel


Hi Dear,

You may do the following:

SAM --> kernel configuration --> Configurable parameters --> Then we have to select any parameters (Ex: maxvgs) by clicking sapce bar --> Action --> Modify configurable parameters--> Now we have to enter the new value in "Formula / Value ---------"---> then Action --> Apply tuned parameter set (For applying new changes) ---> process new kernel (It will backup old kernel like "vmunix.prev" & "system.prev" and build the new kernel like "vmunix" & "system".
