Adding virtual adapters to the hosting i5/OS partition

After the IP Telephony partition is created, you need to create virtual adapters in the i5/OS partition to support virtual I/O and, optionally, a virtual console. The virtual adapters must be created in the partition profile of the i5/OS partition, and also need to be added dynamically (via Dynamic LPAR) to the running state of the i5/OS partition.

Perform the following steps to add a new virtual adapter to the i5/OS partition:

1. From the HMC, right-click the i5/OS partition and select Properties. The properties window for the logical partition will displayed (Figure 3-29).

Figure 3-29 Hosting i5/OS partition - partition profile properties

Note: As mentioned, the adapters to support virtual I/O must be added twice:

򐂰 The adapter is added to the partition profile of the i5/OS partition to ensure that the change will be permanent across IPLs of i5/OS and deactivations and reactivations of the logical partition.

򐂰 Dynamic LPAR is used to add the virtual I/O adapter to the running state of the i5/OS partition to make the adapter available for immediate use.

2. Click the Virtual I/O Adapters tab to display the virtual I/O adapters that are currently defined in the partition profile. A list of adapters will be displayed (see Figure 3-30).

3. To create the virtual SCSI Server adapter that will provide the I/O resource to the IP Telephony partition, ensure that the SCSI tab is selected and then click the Create server adapter button.

4. On the Virtual SCSI - Server Adapter Properties window (see Figure 3-31 on page 80), complete the fields as follows:

– Server slot: This is the slot number for the adapter being created. This slot number must match the slot number the virtual Client adapter that the IP Telephony partition is pointing to.

– Slot connection settings: select Only selected client partition can connect.

– Client partition: select the name of the IP Telephony partition from the pull-down list.

– Client partition slot: The slot number of the virtual SCSI Client adapter in the IP Telephony partition.

The virtual SCSI Client adapter in the IP Telephony partition needs to point to the virtual SCSI Server adapter in the hosting i5/OS partition. Likewise, the virtual SCSI Server adapter in the hosting i5/OS partition needs to point to the virtual SCSI Client adapter in the IP Telephony partition.

As an example, Figure 3-32 shows the properties of the virtual SCSI Server adapter from the hosting i5/OS partition and mappings to the properties of the virtual SCSI Client adapter in the IP Telephony partition.

5. After you complete the fields of the Virtual SCSI - Server Adapter Properties, click OK.

Back on the Logical Partition Profile Properties window, click OK.

At this point the virtual SCSI Server adapter has been added to the profile of the hosting i5/OS partition, which means that the next time the i5/SO partition is started from the HMC, the adapter will be available. To add the adapter to the i5/OS partition without a

restart of i5/OS requires that the adapter be added to the running state of the partition through the use of Dynamic LPAR.

The virtual SCSI Server adapter needs to be added twice to ensure that it is available to support virtual I/O to the IP Telephony partition without a restart of i5/OS, as well as to ensure that the adapter is available across restarts of i5/OS.

6. To add the virtual SCSI Server adapter to the hosting i5/OS partition, right-click the i5/OS partition (not the partition profile) and select Dynamic Logical Partitioning→ Virtual Adapter Resources→ Add / Remove; see Figure 3-33.

Note: Two other adapters may be added to the i5/OS partition profile. A virtual Ethernet adapter may be required to support forwarding traffic to the IP Telephony partition and a virtual Client Serial adapter may be added to support access to the IP Telephony console through the i5/OS virtual console support.

7. On the Dynamic Logical Partitioning - Virtual Adapters window (Figure 3-34), ensure that the SCSI tab is selected and then click the Create server adapter button.

8. On the Virtual SCSI - Server Adapter Properties window (Figure 3-35 on page 83), enter the following information:

– Server slot: This is the slot number for the adapter being created. This slot number must match the slot number that the virtual Client Adapter in the IP Telephony partition is pointing to.

– Slot connection settings: select Only selected client partition can connect.

– Client partition: select the name of the IP Telephony partition from the pull-down list.

– Client partition slot: The slot number of the virtual SCSI Client adapter in the IP Telephony partition.

Click OK.

Note: The information entered for the adapter should match the information defined for the virtual Server SCSI adapter in the partition profile of the hosting i5/OS partition.

9. Back on the Dynamic Logical Partition - Virtual Adapters window, click OK.

Now that the virtual SCSI Server adapter has been added to the i5/OS partition, the virtual I/O configuration diagram shown in Figure 3-36 can be updated to reflect the attachment of the two virtual SCSI adapters.
