I think this is the answer you are looking for...

You have to get your HMC involved because the vio server and your client LPAR can only see their own slot numbers for their adapters. I don't think either can see the other server's slot number, maybe they can but I'm not sure how.

Here is how it can be done though. In this example, slot 11 on the VIO server connects to slot C9 on the client.

Get the slot number of the vscsi0 from the client side using "lsslot -c slot":
Code:
client_lpar:/:$ lsslot -c slot | grep vscsi0
U8205.E6B.0110000-V1-C9   Virtual I/O Slot  vscsi0
client_lpar:/:$

Assuming your managed system's name is "MANAGEDSYSTEM", query your HMC with the 'lshwres' command and grep out your client LPAR's hostname and slot number. From this command you'll see the client slot to VIO slot association (make sure to put the comma inside the double-quotes of the grep):
Code:
client_lpar:/:$ ssh -q hscroot@hmchostname lshwres -r virtualio -m MANAGEDSYSTEM --rsubtype scsi --level lpar | grep "lpar_name=client_lpar," | grep "slot_num=9,"
lpar_name=client_lpar,lpar_id=1,slot_num=9,state=1,is_required=0,adapter_type=client,remote_lpar_id=39,remote_lpar_name=vio1,remote_slot_num=11
client_lpar:/:$

You can verify the resulting VIO slot number information by looking at the 'lsmap -all' output on your VIO server:
Code:
vio1:/home/padmin:# lsmap -all | more
SVSA            Physloc                                      Client Partition ID
--------------- -------------------------------------------- ------------------
vhost0          U8205.E6B.0110000-V39-C11                    0x00000001

Need to replace a broken PV in a VIO VG used for client LPARs (and it won't release the old one)

I have a broken PV in a VIO VG that's used to support client LPARs using LVs. On the client LPAR, I reduced all PVs from the relevant client VG and thus deleted it. I.e. there is no client LPAR using the VIO VG. Yet when I try to reducevg the VIO VG, it complains that the LV hosted on the PV is... (2 Replies)

NAME

       rarpc - Reverse Address Resolution Protocol client

SYNOPSIS

       count] interface_name

DESCRIPTION

       the Reverse Address Resolution Protocol client, implements the client portion of the Reverse Address Resolution Protocol (see It sends RARP
       requests for the specified interface's hardware address and waits for the response from the RARP server.  can be used during boot-time ini-
       tialization to find the IP address of an interface.  To do so, set the i] variable of interface i with in

       Options are:

	      Print debugging information.

	      Use ethernet encapsulation only.

	      Use SNAP encapsulation only.

	      Transmits count requests and waits for each one to time out before
			       giving up.

	      interface_name   Identifies the interface to request information about.

       If  a  response	is  received, it prints the IP address to its standard output.	This information can be used to configure the interface as
       seen in

       If a response is not received, the client will retransmit after 2 seconds, and then after 4 seconds.   After  that,  retransmissions  occur
       every 8 seconds.

RETURN VALUE

       Exit  status  is 1 if the command fails or no RARP response is received.  Exit status is 0 and the IP address is printed to standard output
       if a response is received.

LIMITATIONS

       1. The client cannot be run at the same time a daemon is running on the same interface.

       2. The client supports only ethernet, 100VG and FDDI network interfaces.
