Kernel Reconfiguration

Hi

How to increase the maxdsize and maxsize parameters and reconfigure the kernel. Doing this in SAM gives errors

Re: Kernel Reconfiguration

For HPUX 11.x:

Save the old kernel
# cp /stand/system /stand/system.prev
# cp /stand/vmunix /stand/vmunix.prev
# cp ?R /stand/dlkm /stand/dlkm.vmunix.prev

2.) Retrieve actual system file from kernel
# /usr/lbin/sysadm/system_prep ?s /stand/system

3.) Use kmtune to change the kernel parameter in the system file, e.g
# kmtune -q madsiz
# kmtune ?s maxdsiz=0x10000000
(this changes /stand/system and sets maxdsiz to 256MB)


4.) Build a new kernel /stand/build/vmunix_test
# mk_kernel

5.) if mk_kernel was successful, make sure the new kernel is loaded after reboot
# kmupdate

6.) Shutdown the system
# shutdown ?r 0
