MSwift — Thu, 26 Mar 2009 20:07:05 GMT

Pleae let me know if there are any changes in commands for 11.23, i have used these for 11.0

Get the current values

kmtune -l

preparing to build

cd /stand/build
/usr/lbin/sysadm/system_prep -v -s system

Build the kernel
mk_kernel -s system

Move the old system and kernel
mv /stand/system /stand/system.prev
mv /stand/vmunix /stand/vmunix.prev
mv /stand/dlkm /stand/dklm.vmunix.prev

Move the new system file and new kernel

mv /stand/build/system /stand/system
kmupdate /stand/build/vmunix_test

reboot

Hi:

Kernel maintenance has changed drastically in 11.23. You should read:

Also to update the values i normally use

Update the tunable values using kmtune
kmtune -S /stand/build/system -s semmns+50

still possible?

Thanks

For 11.23, you should use kctune instead of kmtune. And it might be easier to do it in sam, which will check any modification.

Hi:

At 11.23, 'kmtune' has been become 'kctune'.
