Setting maxdsize with ignite-ux

[Jackie Wright]

I'd like to automatically set the maxdsize to 1.5 times the physical memory of the host machine. Is there a way to do that via ignite-ux scripts? For instance, is there a parameter or config file I can use with bootsys to set the maxdisize on host machine when I ignite it?

Yes,

If you just want to hardcode the maxdsiz value, it's easy. Create your own config file (it's better to create under the same directory where your depot config files are there) say kernel.cfg like this

sw_source "Kernel Changes" {
source_format = cmd
}
sw_sel "Others" {
sw_category = "Kernels"
sw_source = "Kernel Changes"
mod_kernel += "maxdsiz xxxxxxxx"
mod_kernel += "npty 1024"
}

Then add this entry to your /var/opt/ignite/INDEX file to the section
where you have your Golden Image/Depot information is kept.

For ex.,


cfg "HP-UX B.11.00 Default N-class" {
description "N-Class OS"
/opt/ignite/data/Rel_B.11.00/config"
"/opt/ignite/data/Rel_B.11.00/hw_patches_cfg" "/var/opt/ignite/data/Rel_B.11.00/Nclass.cfg"
"/var/opt/ignite/data/Rel_B.11.00/kernel.cfg"
"/var/opt/ignite/config.local"
}

To achive what you wanted, you probably have to write a postinstall script to check the memory of the system, then calculate the maxdsiz and then modify system file with kmtune -s, then build the kernel. You can reference this script again from the INDEX file.
