HP UX System Management Software manual Example

Example 1

In this example, if the client’s root disk is smaller than 8.5 GB and has less than 1 GB (1024 MB) of random access memory (RAM), then the primary swap partition size (_hp_pri_swap) is set to 512 MB; otherwise, it is set to 1 GB. If the disk is larger than 8.5 GB, then _hp_pri_swap is set to 1024 MB or 4096 MB, depending on the memory size.

Add the following lines to the end of the file /var/opt/ignite/config.local as this file is typically referenced in all configurations defined in the /var/opt/ignite/data/INDEX file:

#default to very minimal swap of 8500MB

#unless the disk is larger than 8.5

#and we have more than 512MB RAM

(disk[_hp_root_disk].size < 8500MB)

{

(memory < 1024Mb) {

init _hp_pri_swap=512MB } else {

init _hp_pri_swap=1024MB

}

} else {

(memory < 2048Mb) {

init _hp_pri_swap=1024MB } else {

init _hp_pri_swap=4096MB

}

}

You can also put this in a separate file, for example, /var/opt/ignite/data/Rel_B.11.11/ custom_cfg, and then add that file name to the desired cfg clause in the /var/opt/ignite/ data/INDEX file.

Additionally, you can add this to the configuration file created for automatic installations. If the _hp_pri_swap parameter is set later in the order of files searched in the cfg clause, this setting is overwritten. The configuration file parsing order and precedence is documented in instl_adm(4) and in “Using configuration files” (page 161).

CAUTION: The per-client configuration file in /var/opt/ignite/clients/client used for noninteractive installations is overwritten as part of the installation process.

Example 2

To force the installation of a patch bundle if the client matches a regular expression, such as a hardware architecture type like J6700 or J6750 PA-RISC workstations, add the following lines to the end of the /var/opt/ignite/data/Rel_B.11.11/custom_cfg configuration file:

#check for H/W model J6700 or J6750

#and add the Misc_Patches bundle if true

(hardware_model ~ "9000/785/J67[05]0") {init sw_sel "Misc_Patches" = true}

Example 3

In this example, Ignite-UX runs a previously created post-installation script and increases a tunable kernel parameter if it determines the client is a C3600, C3650, C3700, or C3750 workstation. If not, it sets a default value for the kernel parameter:

post_config_script += "/var/opt/ignite/scripts/new_C_series_special" (HARDWARE_MODEL == "9000/785/C3[67][05]0") { mod_kernel += "maxuprc 300" } else {mod_kernel += "maxuprc 100"}
