Advanced POWER Virtualization on IBM System p5 - Previous ...

In this scenario, we attach each Virtual I/O Server with one Fibre Channel
adapter directly to a DS4200. In our case, we used this configuration only to
show the basic configuration.
When using only one Fibre Channel per Virtual I/O Server, you need an
additional switch to have a supported configuration. In this case, it is important
that the SAN zoning be configured such that the single HBA in each Virtual I/O
Server LPAR is zoned to see both storage controllers in the FAStT. If a second
HBA is used for additional redundancy, the storage administrator must ensure
that each HBA is zoned to only one of the DS4200 controllers. Rules for
attachment of FAStT storage units to AIX can be found in the Storage Manager
documentation of the Storage Manager products.
On the Virtual I/O Server, the RDAC driver is always provided, regardless of the
existence of multiple Fibre Channel adapters.
4.4.1 Setup on the HMC
Use the following steps to set up the scenario:
1. Create two Virtual I/O Server partitions and name them VIO_Server1 and
VIO_Server2, following the instructions in 3.2, “Creating a Virtual I/O Server
partition” on page 124. In step 10, select one Fibre Channel adapter in
addition to the shown physical adapter.
2. Install both Virtual I/O Servers by following the instructions in 3.3, “Virtual I/O
Server software installation” on page 142.
3. After the successful installation, you can map the world wide names of the
Fibre Channel adapters to the created LUN. Use the cfgdev command to
make the disks available on the Virtual I/O Server.
4. Create two client partitions named DB_server and APP_server following the
instructions in 3.4.3, “Creating client partitions” on page 151. Create the
server adapters when you create the client adapters using dynamic LPAR
following the plan in Table 4-3 on page 219 and Table 4-4 on page 219. Also
add one or two virtual Ethernet adapters to each client, one adapter if you
plan on using SEA Failover for network redundancy, as described in 4.3,
“Scenario 2: SEA Failover” on page 211, or two adapters if you plan on using
Network Interface Backup for network redundancy, as described in 4.5,
“Scenario 4: Network Interface Backup in the client” on page 234.
