One of our systems, running HP-UX 11.00, is going to be rebooted after being up continuously for over 500 days. Prior to the reboot, it was suggested by an HP technician that we "gen the kernel" to be sure that we can create a valid bootable kernel.
I have not heard of this step, nor the commands that are involved with it. I was hoping someone would know what this is, what the command(s) are, and what it entails.
Thanks.
Solved! Go to Solution.

Re: gen the kernel before a system reboot
IF the system has been up and stable, and
IF no PHKL, or other patches requiring kernel updates have been installed,
I wouldn't really worry about it.
What is the time stamp of the /stand/vmunix file? Is it the same as, or older than, the last time the system was booted? If so, I wouldn't regen the kernel.

Re: gen the kernel before a system reboot
Never heard that one. I know of boxes, especially workstations, that stay up for 1000 days and then reboot just fine. No difference. No problem.
I would even say you got bad advice from someone how shouldn't be giving you advice, and commend you for recognizing the bad advice and double checking.
There are people on this forum with lifetimes of expertise in HP-UX, verses paid for support from Costa Rica that uses people who can hardly speak English, or people who never heard the word "HP-UX" before they got their current job.

Re: gen the kernel before a system reboot
Thanks for that vote of confidence. At this point I am going to hold off on the "gen the kernel" and reboot option.
This issue did give me an idea: Maybe there is a(re) runaway process(es) that is/are taking up swap space and causing this issue. To that end, is there a command that I can use that would show what processes are taking up the most swap space? Thanks.

Re: gen the kernel before a system reboot
To me, this sounds totally unnecessary, but reassuring. Maybe you could flip a coin.

Re: gen the kernel before a system reboot
Could you open another thread? I'm concerned that other members will miss your newest question and consider this thread closed.
Don't forget to assign 0 to 10 points and close the thread. Sometimes they get responded to years after being posted. (* yep, it does happen *)
