We are using a DS which has native support in multipath tools run multipath -t. If so, are these working fine for you? If the active path fails, multipath-tools has to send specific scsi command through the passive paths to requeste the controller failover of the lun. It prioritized the IO traffic so it should stay on the preferred path. Thanks in advance for any help. The big question is, will it work when you connect the v to the xenserver, and I think it will but I am not sure.

Storwize v and XenServer – Storage – Discussions
I’m ok, about your answer, but the final question is: I already checked the HCL. Have you tried the linux multipath-tools? When it’s come in? We are using a DS which has ss4700 support in multipath tools run multipath -t. At the rda we have a small pool with 2 xenservers on 6. Answered question This question has been answered. Storwize v is supported on 6. I’ve tried installing linuxrdac It prioritized the IO traffic so it should stay on the preferred path.
If working fine, is there any reason to get RDAC working again? If the active es4700 fails, multipath-tools has to send specific scsi command through the passive paths to requeste the controller failover of the lun. We have a DS When both paths to the storage are enabled, we have a very unreliable cluster.
Thanks in advance Maurizio. Does anyone know how to get around this?
Where we are stuck is trying to initialize the LUNS and set them as shareable. But in some specific conf it’s can work, with many “parrasits” in the fdisk -l but it’s works.

From what you say, ditching RDAC might be a better option. Upvote if you found this answer helpful or rrdac. Most critical hotfixes and driver updates were made.
