[Users] Ims shared disks and ovirt storage
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 Gianluca

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... Regards, René
Thanks in advance Gianluca

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.

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.
