unable to assign tiers with RDM disk - bug or feature?

Hi all,

 

I'm trying to deploy HP StoreVirtual VSA with a local RDM disk on esxi 5.5.

 

The RDM was created with "vmkfstools -z" and attached to the VSA VM to be Tier 1. I also have a vmdk on SSD for the second disk, that I would like to use as Tier 0.

 

The problem is when I try to assign Tier 1 to my RDM SATA drive, I get an error "SCSI device doesnt match (/dev/scsi/host1/bus0/target0/lun0/part2=1)" .. screenshot attached. This unhelpful message does not give a clue...

 

Why I cannot assign tiers with RDMs when I'm able to with vmdks? Any way to further troubleshoot this issue? Any help would be appreciated.

 

Thank you,

 

Andrei

Hi

If the RDM is a local storage disk  it is not enabled by default to be presented to VM guest

you must enable this feature in the ESXi managmet.

Hi,

 

thank you for your reply. As I stated in the original post, the RDM disk is created already with "vmkfstools -z" and attached to the VSA VM, so your reference to VMware KB article is unfortunately not helpful.

 

I would like to know if anyone was able to successfully tier the local RDM in HP VSA, or this feature is broken?

 

Thanks again!
