virtual flash resource management is unable to recognize non ssd drive (marked as ssd)

[lvaibhavt]

Hi All,

In my home lab I am able to do VMware vSphere Flash Read Cache (vFRC) pratical, I do not have ssd on my desktop.

In vmware workstation 11 -- I created an esxi 5.5 and added local hdd. This is a non ssd drive and I marked it as SSD.

in VC the drive is now seen as ssd however in VMware vSphere Flash resource management when I click on add capacity it is unable to see the drive (non ssd marked as ssd).

Any suggestions on how to get it going.

Thanks

Can you check any existing partition are there on the disk. If there is no data on the disk, remove all partitions , rescan and check after that

Hi Techie,

Thanks for replying --- there is no partition on the disk. It was a RAW disk formatted with vmfs.

guys any suggestion on how to go about it .....

AFAIK, the SSD should be visible as "local". Can you run the command "esxcli storage core device list -d <nna.id>  and check if the device is showing as local ssd

I believe that the disk should not have vmfs. Can you remove the vmfs and provide a normal, un-partitioned ssd disk

I agree, it should not have VMFS, is it showing as a local datastore under "Storage" for that host? If so, unmount and delete that datastore. Then try again.
