Unable to unclaim path. Some paths may be left in an unclaimed state. You will need to claim them manually using the appropriate commands or wait for periodic path claiming to reclaim them automatically.

In preparation for my vBrownbag presentation on preparing for the VCP 6: DCV, I needed to assign the SSD tag on one my virtual disks. I followed William Lam’s post about how to trick ESXi into thinking a spinning disk was an SSD, you can read that here. Upon trying to apply the new claim rule on the device, I got the error:


There was active IO on the device at the time of reclamation. I rebooted my host and now every host in the cluster sees it as an SSD.


Now on to labbing up on vFlash (though I don’t think anyone uses it).

    Thanks mate!

    Rebooting the host was what I was missing 😉
