2. Configure the SEA, as described in step 1 to 4 in 3.4.2, “Creating a Shared Ethernet Adapter” on page 149. In our example, we use the network settings shown in Table 4-5 and Table 4-6. Table 4-5 Network settings for VIO_Server1 Setting host name Value VIO_Server1 IP-address 9.3.5.110 netmask 255.255.255.0 gateway 9.3.5.41 Table 4-6 Network settings for VIO_Server2 Setting host name Value VIO_Server2 IP-address 9.3.5.112 netmask 255.255.255.0 gateway 9.3.5.41 3. Check for the attached DS4200 disks using the lsdev command with the -type flag, as shown in Example 4-8. Example 4-8 Check for the DS4200 disks $ lsdev -type disk name status description hdisk0 Available 16 Bit LVD SCSI Disk Drive hdisk1 Available 16 Bit LVD SCSI Disk Drive hdisk2 Available 16 Bit LVD SCSI Disk Drive hdisk3 Available 16 Bit LVD SCSI Disk Drive hdisk4 Available 3542 (200) Disk Array Device hdisk5 Available 3542 (200) Disk Array Device hdisk6 Available 3542 (200) Disk Array Device hdisk7 Available 3542 (200) Disk Array Device hdisk8 Available 3542 (200) Disk Array Device The output of the command lists four internal SCSI disks and five DS4200 disks. 4. You can use the fget_config command from the DS4200 to get the LUN to hdisk mappings, as shown in Example 4-9 on page 223. We will use hdisk6 and hdisk7 on VIO_Server1 for our clients. 222 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5

Example 4-10 Listing the LUN to hdisk mapping using the lsdev command $ lsdev -dev hdisk6 -vpd hdisk6 U787B.001.DNW108F-P1-C3-T1-W200500A0B8110D0F-L3000000000000 3542 (200) Disk Array Device PLATFORM SPECIFIC Name: disk Node: disk Device Type: block Chapter 4.
