Hmmmm,
the "PVID" is the "physical volume ID" and is the property of a (physical or virtual) disk - it has absolutely nothing to do with networks at all. It is an identifier of the disk, quite like the UUID in Linux, by which the device is identified in the volume group.

Show the profile (from the HMC) of the new lpar. I suppose it doesn't have a virtual network adapter as resource. You need to create this on the VIOS first, then add it to the LPAR profile. only then you can start and install the system successfully. I suggest you read the IBM documentation, i.e. these articles:

Configuring a virtual Ethernet adapter
Configuring virtual Ethernet on the Virtual I/O Server
Virtual adapters

It is simply to complex to walk you through the whole process via a forum without knowing all the details of your environment because there are so many ifs and buts and althoughs involved. So, if you have some specific questions after reading up about the IBM virtualisation or if you need some general principles explained i'd be glad to help but what i think your problem is would be best solved by hiring a knowledgeable person and let this person do it for you, eventually teaching you about how it is done in the process.

To get you some further pointers on where you (presumably) stand: You have probably a SEA (shared ethernet adapter) configured on the VIOS (this is the common setup i talked of before). You need to base the virtual adapter on this. There is a HMC screen where you can do that - depending on which HMC version you use because the menus changed between the "classic" and the "enhanced" version ("enhanced" being an euphemism for "nearly unusable", but that is another story) you will find it in different panels. Honestly, i have no HMC at hand and can't you talk you through the menus off the top of my head.

Once you have this adapter defined (you need to do it for both VIOS) you need to add it to the profile of the LPAR, then start the LPAR anew. Notice that rebooting is NOT sufficient. You need to shutdown -h, then start it again.

I hope this helps.

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME

       URI::URL - Uniform Resource Locators

SYNOPSIS

	$u1 = URI::URL->new($str, $base);
	$u2 = $u1->abs;

DESCRIPTION

       This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to
       be distributed with the libwww-perl library.

       The following differences exist compared to the "URI" class interface:

       o  The URI::URL module exports the url() function as an alternate constructor interface.

       o  The constructor takes an optional $base argument.  The "URI::URL" class is a subclass of "URI::WithBase".

       o  The URI::URL->newlocal class method is the same as URI::file->new_abs.

       o  URI::URL::strict(1)

       o  $url->print_on method

       o  $url->crack method

       o  $url->full_path: same as ($uri->abs_path || "/")

       o  $url->netloc: same as $uri->authority

       o  $url->epath, $url->equery: same as $uri->path, $uri->query

       o  $url->path and $url->query pass unescaped strings.

       o  $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters)

       o  $url->params and $url->eparams methods

       o  $url->base method.  See URI::WithBase.

       o  $url->abs and $url->rel have an optional $base argument.  See URI::WithBase.

       o  $url->frag: same as $uri->fragment

       o  $url->keywords: same as $uri->query_keywords

       o  $url->localpath and friends map to $uri->file.

       o  $url->address and $url->encoded822addr: same as $uri->to for mailto URI

       o  $url->groupart method for news URI

       o  $url->article: same as $uri->message
