Xen users - Mar 2011 - XCP - Attach to existing LUN''s on a SAN (iscsi) ?

Hi all,

I''m using a Dell MD3200i (iscsi) storage array.
>From XCP, is there a way to attach existing Lun''s from the array,
and expose
them into VM''s as block devices ? I would like to re-use existing
virtual
drivres from my SAN, so "lvmoscsi" SR''s cannot be used here.

Should I use "xe sr-create type=iscsi" directly ? And then create
manually
pbd''s, vbd''s and vdi''s ?

Regards,
Pierre

Actually, it seems I can create a "iscsi" SR (not a
"lvmoiscsi", really a
"iscsi") by using :

xe sr-create name-label="MyLunOnSAN" \
type=iscsi \
shared=true \
device-config:target=192.168.131.101 \
device-config:multihomelist=192.168.131.101:3260,192.168.133.101:3260,192.168.130.102:3260,192.168.132.101:3260,192.168.133.102:3260,192.168.132.102:3260,192.168.131.102:3260,192.168.130.101:3260
\
device-config:targetIQN=iqn.1984-05.com.dell:powervault.md3200i.12345678910
\
device-config:port=3260 \
device-config:SCSIid=36782bcb00006b1500000f5d24d8c54ab \

So I would like to create a kind of raw "SR", mapped the SCSIid of the
requested Lun.

My problem here: 
- when this SR is created, two pbd are created, which is ok
- the "multupath -ll" shows my scsid, which is also ok
- BUT a "xe vdi-list sr-uuid=<id returned by xe sr-create" returns
all the
virtual disks of the SAN (ie : all the Lun''s)! I expected only one
here, the
Lun of the virtual drive I requested with the SCSIid param.

What''s wrong with my sr-create ?

Thanks,
Pierre
