Hi,
It depend of the release of hpux. With 11.31, I suggest you to not install pp. :)
When you install the pp on older hpux, you have to reboot the systeme, so after that when you could do /sbin/powermt config and after /sbin/powermt save.
To see /sbin/powermt display dev=all or
powermt display paths.
For more info, look at powerlink.emc.com

1.Download and install latest or EMC recommended powerpath software from powerlink.emc.com.
2.Download and install naviagent software.
3. go to /etc/NAVIAGENT/agent.config file and go to line where you will find something like root@server. there you put entry like

root@
root@

4. Stop and start agent
/sbin/init.d/agent stop
/sbin/init.d/agent start

thats all

Hi,
Navisphere and naviagent is indeed if you have a clariion. If you have a symmetrix, of course you could forget navisphere.
Look at EMC PowerPath for Linux 5.1 Install and Admin Guide. You have step by step how to install and configure pp on linux with clariion or symmetrix.

First - make sure you have a good recovery tape done for your box. Just standard pre-install stuff.

You can download the tarfile from http://powerlink.emc.com
If you don't have an account, then create one. Go to Support/Download/[P] and Powerpath. I will assume you have rights to download. And will assume you want to load PowerPath version 5.1, since that's what I have on my 11.23 boxes.

Make sure you download the FULL INSTALLATION!!

OK...with tarfile on your server on a mountpoint you can:

Uncompress the tarfile.
swinstall -x autoreboot=true mount_all_filesystems=false \ -s /path/oftarfile/EMCPower.HP.x.x.tar EMCpower5.1

It will install and it will reboot the box, since it rebuilds the kernel. And of course you should make a brand new recovery tape, cause you just changed the box!

Now once your box is back up you need to register your license key:
You can run emcpreg -install (and enter it)

powermt config
powermt display dev=all
To show you how your policy is set)
I like mine set to optimal (you choose)

powermt set policy=so dev=all
powermt display dev=all
To confirm it changed
powermt save
To save your new configuration.

Run " powermt ? " to see all the different powermt commands.

Remember, when add or take away disk to run "powermt config" and a "powermt save" to update things.

It's also good to run "powermt check" to ensure that you don't have any dead links because you forgot to update things.

Hope this helps get you started.
Regards,
Rita
