iscsi direct luns with multipath

[alma21]

Just select the iSCSI storage and the LUN in the `Add: Hard Disk` panel.

If there's a multipath device available for the LUN, it will use the multipath device. No need for you to manually select the multipath device. Just make sure that one is available if you want redundancy/failover. The iSCSI plugin will make sure that multipath devices are selected for LUNs that have them when starting the VM.

Hi,

is there something similiar for Fiber channel LUNs -> attach through the PVE storage stack to VM ... or is the local multipath device passthrough (qm set --scsi0 ....) the preferred way here ? beside complete PCI/FC HBA passthrough to VM .... or are there any plans to support virtual HBAs / NPIV in future ? thanks

fiber channel multipathing works effectively identically to iscsi; once the devices are captured by multipathd they'll just show up in /dev/mapper and you can use them as any other mapper device- so you can put a vg on it or map is as a drive redirect to a vm.

That isnt a function of PVE. Ask your HBA vendor; if they can give you a linux driver that can present as virtual devices, you'd be able to use it in pve.

--edit- on reflection, this might still be possible using a FCOE bridge. I never tried such a thing but conceptually its possible.
