Removing PowerPath Completely

MSwift — Thu, 03 Mar 2011 15:29:02 GMT

I am working on a RHEL 5.5 server to remove PowerPath completely from the system. I have unmounted all the filesystems and deactivated the VG vgchange -a n but still when i want to stop the PP it complains the devices are open. I have even removed the vg and still it complains. Not sure what i am missing. Could someone help?

Thanks

Mike.

The PowerPath documentation from EMC includes detailed instructions for removing it too. Have you followed the documented removal procedure?

The documentation is available in EMC Powerlink website (powerlink.emc.com). You will have to create an account, and may need to associate a supported EMC product serial number with your account to fully access the website.

Not really familiar with P.Path.

Heed Matti's advice and seek out the correct procedure.

Maybe stop whatever daemon or module as well?
