VmWare Esxi 4 extend datastore sanity check please.

I have two diskless hosts running ESXi 4 connected to a DS3200.

I have added another drive to the array that hosts the datastore for the
guest VMs.

I am now ready to extend the logical drive and datastore and would like
to make sure I have found all the secret steps and would appreciate
confirmation that this is next:

1) In Storage Manager 10 run a script:
set logicaldrive VMDatastore addcapacity 297GB
2) Wait on extension to the logical drive to complete.
3) In vSphere client:
a) Go to Inventory > Hosts and Clusters.
b) Select one of the hosts.
c) Configuration tab.
d) Hardware > Storage Adapters.
e) Right click on an adapter tied to the DS3200 and click Rescan.
f) Hardware > Storage.
g) Right click on the datastore and click on Properties.
h) Click on increase button.
i) Wait for completion.

Afterwards I can than assign Datastore space to new or extend existing
guest's virtual drives.

Thanks.
