ESXi 4.1 Upgrade Error

Posted on 2011-10-05
Last Modified: 2012-05-12
I loaded ESXi 4.1 to a USB on a server which had 3.5 loaded locally. I see the datastore of the 3.5 and added the one VM it has on it to inventory (added the VMX file to inventory). then went to start the VM and get the following error

"Module DevicePowerOn power on failed.
Unable to open the SCSI device '/vmfs/devices/genscsi/vml.020100000050060b00005f5c4a556c74726975' (scsi0:2): Could not find the file. "

Any Ideas? It does have one snapshot, but I have done this before on other servers and it loads up fine. I unplugged the USB and restarted back to the 3.5 build and the VM loads fine.

    Can you just try one quick test, and add a new VM template (with NO OS) and check if you can start the VM?

    It's appears it does not like the datastore reference

    Is the server on the HCL?

    I did some research and see the device in question (0:2) looks to be the SCSI tape device (I did not originally put this VM into service).  to stay in the maintenance window I put the server back online with 3.5. in the next maintenance window I think I will edit the configuration and take out that SCSI device (under 4.1) and then power it on, then add in the device again if it powers on Ok

    Yes it is in the HCL (Dell 2900) I will try your test as well first once I can get the server back offline in the next maintenance window

    Accepted Solution

    If it's a tape device, it may not be supported in 4.1
