kernel parameter

[Jun Zhang_4]

I did
kmtune -s maxdsiz=0x08000000
on my D370 running 11.00.
kmtune -q maxdiz
shows that the parameter was already changed, sam shows the same new value for both current and default. sam also said maxdsiz is of type static.
Do I still need to rebuild the kernel? Or do I still need a reboot? Or do nothing?

Hi Jun,

Yes you do need to rebuild the kernel & yes you do need to reboot.

Yes, every kernel change needs a Kernel rebuild and reboot of the server (unless there is a dynamic changable Kernel parameter).

Yes you need to reboot - unless that was already what it was set to.....

Hi you need to build the kernell and reboot which can be done with sam or manually.

On 11.00, thought there was introduction of dynamic kernel rebuild, most of the parms still need a real reboot. So yes rebuild the kernel and the reboot your server for your new maxdsiz to take effect.
