Emergency UNIX and Linux Support

I've got critical patching this weekend on 6 HP UX machines, back to back and the customer has requested to shutdown, and halt the machines and to bring it up at a later period. The thing is the servers are located offshore and we are just the support team. I have a special login thru a console where I can shutdown and bring up the servers.

Here's the shutdown and halt command:

Code:

shutdown -h now

What is the command to start up without actual pressing on the power on button?

Im using HP UX 11.31 here

Thanks in advance.

be kind and reply me please. I need to put up calendar notification for the guy to run commands on Sunday

Every Integrity server I've seen so far has some kind of remote management facility, most probably yours too. Just connect to the iLO card and you can power up/down the server.

If this is a cluster or there are NFS mounts you will need special instructions to shut down in a sensible manner. These instructions may or may not include a "shutdown" command.


You will need to know more about you "special login thru a console" and what piece of hardware you are connected to and how to toggle between console and server remote management. Is it an iLO (Integrated Lights-Out) or a MP (Management Processor) or a Web Console? We assume it is not just a telnet session.


The unix "shutdown" command just shuts down the Operating System and halts the processor. It does not turn the power off. Most remote power controls only control the system unit not any add-on hardware such as disc arrays.


Beware that unix "shutdown" does not shut down databases etc. unless "rc" scripts have been installed to achieve this.


If you are in a hurryand you have already closed all applications and client connection, this method answers any prompts:

Code:

cd /;/sbin/shutdown -h -y now

Hi all

Thanks for your replies. Unfortunately we don't have iLO for this particular client, just a remote console IP which can be accessed from telnet session. This box had vpar and npar which had to be turned off first then halt the system. it was a messy patching that weekend. Someone googled and found it had to be done from console itself, i think MP options.

Thanks all!

`init 5` powers off the box in Solaris.. Check it out whether it works in HP-UX as well.

See if you can find documentation on init. That should give you several levels of operation you can initiate from your login. Be careful though, you would need to use the same level of access to log in again.

u can try these

reboot
# shutdown -r -y now
or

# telinit S
# shutdown -y now # shutdown 0
