other than on the hmc, it's not possible to add additional virtual scsi adapters to lpars from the Integrated Virtualization Manger (IVM) GUI

when setting up a Power HA (formerly HACMP) Cluster, it's wise to use different vhosts for different storage subsystems

therefore you need to log in to the vio-server, and add the adapter manually from command line, with the command (as padmin):

$ chhwres -r virtualio --rsubtype scsi -p lparname -o a  -s 6

 
when adding more then one adapter, choose different slots

$ chhwres -r virtualio --rsubtype scsi -p lparname -o a  -s 7

$ chhwres -r virtualio --rsubtype scsi -p lparname -o a  -s 8

 
these changes are persistent over reboots
