You should find the following link helpful:
http://www.ovirt.org/Vdsm_Storage_Terminology
As per your other questions, you might find the following guide helpul:
http://www.ovirt.org/Quick_Start_Guide#Configure_Storage
Of not, please rephrase them as they're not clear enough and I'd rather not
guess.

New subject: [Users] [Engine-devel] Fwd: the procedure of storage-related
I'm not that familiarized with the code myself and can't tell you without looking
into it and debugging it.
What I would do is - for any command I'd like the internal flow of - start at the top
(All vds commands are listed when you type vdsClient, without the need to actually run
something).
You can then search the specific command you're interested in in the code, and see the
flow there.
You can obviously run a specific command if you have the correct setup and follow through
with the vdsm.log to see the exact flow. You can, of course, add your own debug messages
to make things clearer for you, as the vdsm log is logged to very frequently.

hi,
maybe i do not make you understand me fully. i am reading vdsm code, but it
is hard for me to understand StorageDomain,StoragePool. before stoargeD(P)
can work, engine must prepare many things.
i want to know the call flow (process) which must be done to make
storageS(P) work.
1.for example, what funcitons you should call if make a stoargeDomain
work.
poolConnectStorageServer->poolCreate->poolConnect->domainCreate->domainActivate.
thanks

The setup flow is:
1. connectStorageServer (this connects the host to storage. i.e. either performs a
'mount' or iscaiadm command)
2. createStorageDomain (only required once)
3. createStoragePool (only required once)
Once you have the pool, on all hosts you perform:
1. connectStorageServer
2. connectStoragePool
And on one (and only one) of the hosts:
1. spmStart
