This is to create a Virtual SCSI Adapter on both VIO servers for the client adapters you created to connect to.

Then we need to update the configuration on the VIO servers themselves which will apply the changes you made to them.

This will complete the connection between the Client LPAR and the 2xVIO servers.

On the HMC check the first VIO server.

In the pop-up menu choose:-

Configuration

Manage Profiles(to open a new window)

Tick the Normal profile checkbox

Under Actions drop-down

choose Edit

Select Virtual Adapters

Under Actions

choose Create SCSI Adapter

Make sure that Virtual SCSI adapter Adapter is set to the Adapter ID you noted earlier (the one you set as the Server Adapter ID in the client LPAR).

Check Only selected client partition can connect

and choose your new LPAR from the drop-down list.

Client adapter ID should be the same as the Connecting Adapter you noted earlier

then hit OK

Then scroll down the list of existing connections and your new one should be listed.

Make sure the Connecting Adapter is the same value as the rest then close the pop-up window to return to the list of LPARs.

Select the pop-up menu again

choose Dynamic Logical Partitioning

Virtual Adapters (to open another new window.)

Under Actions

choose Create

SCSI Adapter

choose the same settings that you did for the Normal profile above.

Then hit OK

and close the pop-up window.

Then repeat this process for the second VIO server.

Run the following command on both VIO servers to get a list of the vhosts

The output is also displayed.

$ lsdev -virtual |grep vhost |awk {'print $1'} |while read v
do
lsmap -vadapter $v |grep $v
done
vhost0          U9119.595.83724B2-V4-C3                      0x00000001
vhost1          U9119.595.83724B2-V4-C4                      0x00000007
vhost2          U9119.595.83724B2-V4-C5                      0x00000008

Run cfgdev to discover new virtual adapter in vios server padmin console.

Run the lsdev command again to see the new vhost number for the new adapter-to-target partition map

Repeat on the second VIO server

The new vhost here is vhost18, on the HMC vio config, the new virtual scsi HBA was given the number 21, this matches the C21. The connected partition does not show up as the hex version of the partition number of the target partition as it has not yet connected.
