I'm testing out unRaid in an esxi environment and have a problem with RDM disks.

 

I've read through most of the relevant threads and this https://lime-technology.com/forum/index.php?topic=17952.0 is what is happening but those solutions are not working. UnRaid boots up just fine and all of my disks show up in the gui. However, when I try to assign a disk it immediately flashes back to "unassigned". I've changed the adapter type from parallel to SAS (and even tried paravirtual) with no change. I also deleted the vmdk pointer files and recreated them using the -z switch, but that doesn't solve the issue. I'm at a loss.

 

Fwiw, the disks were previously assigned to a FreeNAS VM the same way and I'm trying to not do passthrough of the entire HBA. I'm also only using SSDs for this test but doubt that would matter.

 

Edit: I also read through this http://bobbyromeo.com/technology/raw-device-mapping-of-sata-storage-with-esxi-unraid/ but it's unclear why I'd need to manually fdisk the raw drives. Is that necessary for unraid to partition and mount rmd'd disks?

 

Thanks in advance for any help.

 

System info:

Esxi 6.0 u2

Supermicro X10 MB Xeon e5-2667 v4

i use RDM without any problems..

you need one more option on esxi side,

see here: https://lime-technology.com/forum/index.php?topic=51386.msg493146#msg493146

Thanks. I forgot to include that in the OP but I already have that setting. Oddly, if I add the disks as scsi but then change the disk type to sata using the web client it seems to work.
