Hello Friends
I am new to HP-UX.I need some information on the HP integrity server boot process.Can somebody help me on this issue? Apart from that I have one more query. While uploading the patch how can I come to know that the patch need a reboot if the patch readme file is not available?

There is always a patch readme at itrc.com patch database.

If using swinstall, the installer will tell you if a reboot is required.

About the boot:

1) switch the server on
2) selftest will run, EFI will be loaded
3) system will read boot path and the AUTO file, if configured, system will boot from specified disk
4) system will load the OS loader, this will load the kernel, OS will be startet

This is the general process in short version.

Hi,

You can identify the patches which required reboot by the standerd icon (Monitor icon) from ITRC.

All PHKL patches required reboot.Most of the PHSS patches not required a reboot.

>how can I come to know that the patch need a reboot if the patch readme file is not available?

Inside of each patch is the README, in two places. You can use swlist to print it.
It is also there is the shar file.
You can also use swlist to check:
swlist -l product -a readme -s /tmp/PHCO_34668.depot
swlist -l fileset -a is_reboot -s $PWD/depot
