Figure 10 Sample communications resources.
If the IBM i client partition is to use a virtual Ethernet adapter to communicate with an external
network, additional configuration in the VIOS hosting partition must be done. An SEA must be
created in VIOS to bridge the internal virtual LAN (VLAN) to the external LAN. Use the
HMC/SDMC and the instructions in section Network virtualization to perform the SEA
configuration. Ensure that the port VLAN ID (PVID) that you choose for the client IBM i’s VE
adapter matches the PVID that VIOS has in its VE adapter.
9.1.2 End-to-end LUN device mapping
On October 2009, IBM enhanced both the HMC and VIOS to allow end-to-end device mapping
for LUNs assigned to client LPARs, such as IBM i. The new function enables administrators to
quickly identify which LUN reporting in VIOS (or, hdisk) is which DDxxx disk device in IBM i. This
in turn makes it easier to troubleshoot disk-related problems and safer to change a virtualized
disk configuration. In order to correctly perform the mapping, the HMC requires an active RMC
connection to VIOS.
To perform end-to-end LUN device mapping, use the following steps:
 Sign in to the HMC as hscroot user ID.
 Expand Systems Management.
 Expand Servers.
 Click the correct managed system (server).
 Select the correct VIOS by using the checkbox.
 Click Hardware Information  Virtual I/O Adapters  SCSI.
 You will be shown a list of drives associated with their VIOS hdisks.
 Click back on the word Servers in the left hand navigation pane of the HMC.
 Select the correct managed server by selecting its checkbox.
 In the menu below, expand Configuration and then Virtual Resources.
 Click Virtual Storage Management.
 Select the correct VIOS from the list and click Query VIOS.
 Click the Physical Volumes.
 The hdisks that VIOS sees are shown along with the partition that they are assigned to.
On the far right side of the Physical Location Code column, there is a –L#00000… This
is the LUN number associated with the hdisk. This is a hexadecimal number.
 Use the SAN interface to determine which volume has that LUN number. You may have
to convert the hex number to a decimal number (I know, it’s been a while, but you can do
it!). If the SAN is the V7000, look for the SCSI ID as the LUN #.
9.1.3 How to perform IBM i operator panel functions
If the system is HMC-managed, follow these steps:
 Sign in to the HMC with a profile with sufficient authority to manage the IBM i client
partition
 Select the partition.
 Use the open-in-context arrow to select Serviceability  Control Panel Functions and
then the desired function.
If the system is IVM-managed, follow these steps:
