Hello,
I have the chance to work on Intel blades where I have option to confihure
shared disks between them at enclosure level.
Their controller is scsi.
How could I configure as shared storage in ovirt?
I presume neither Fc nor iscsi are possible. .. so what can i do in your
opinion?
Thanks in advance

Is this an Intel modular server, btw?
If yes - create a Fibre channel datacenter and add the storage as FC
LUNs. I can also send you a working multipath.conf for Intel Modular if
required...

Thanks in advance

Yes, it is an Intel modular server (I don't know well this platform
but I think IMS is its acronym)
The multipath working configuration would be more than appreciated ;-)
But.... does this mean there are configuration with dual scsi or is
multipath needed in every case (as I see oVirt config implies
multipath configuration anyway.)

You can contact me if you have questions regarding these server - I
use(d) this system in the company I worked before and on customer side.
The multipath working configuration would be more than appreciated
;-)

Attached is a working multipath.conf for RHEV-H 3.0.
You need a working multipath.conf file if you have redundant storage
controllers.
Find out the wwids of your devices and add them to your
blacklist_exceptions section.
# multipath -ll
mpathb (2222b00015521f5d4) dm-0 Intel,Multi-Flex
size=96G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 0:0:0:1 sdb 8:16 active ready running
mpatha (222140001553601d1) dm-1 Intel,Multi-Flex
size=20G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 0:0:0:0 sda 8:0 active ready running
Don't forget to persist /etc/multipath.conf if you're using ovirt-node!
With this config you don't need the Intel multipath drivers, btw.
Please let me know if you have further questions.
