Description of problem:
In add external disk option, rhevm can provide an option to add the path of the scsi device on the host. Currently there is no such option.
Veritas team, can you please clarify what is expected to be implemented here? example would be great.
Is it possible for the dialogue 'Add Virtual Disk' to provide options to attach files/devices locally available on the host to the VM (corresponding to type 'lun' and 'file') ? Perhaps these files/devices can me made available on all hosts in the RHEVM cluster at the same path by the administrator.
We currently do not support this feature, and it's too lat in 3.5.0's schedule to add it.
We should consider for 3.6.0 planning.
Liron - lets try to see if we can come up with an easy workaround in the meanwhile.

Adding an actual device on the host can be done by selecting FCP.
For local files, we need some additional work.
Thank you for your response. Selecting FC disks is not useful to select Veritas DMP devices (which manages FC disks internally). Hence it would be great if along with local files, an option would be provided to add local scsi devices too.

Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
Isn't this covered by the VFIO feature?

Can you confirm the question on comment #8?

sure. No, storage passthrough is a separate feature (we have generic PCI and USB) which was not requested.
If exposing a PCI device in guest is enough then yes, one can try to use generic PCI VFIO passthrough, bypassing RHEV-M storage UI
Is the Veritas DMP device a PCI device?
DMP is not a PCI device but a pseudo block device just like a DM device and responds to SCSI commands.
Can you please try to passthough the device using VFIO in 4.0. This should work for storage devices.
