The VDI is not available

[Antonio Zec]

Hi,

 

Just had a host with hardware failure and with 3 VMs still on it.

Executed this command for each VM:

 

xe vm-reset-powerstate uuid=<UUID_of_the_VM_to_recover> --force

 

All good so far, I got the VMs back to the pool.

 

Now i wanted to boot the VMs but I get "The VDI is not available".

 

I guess its because the storage is locked on the VMs?

 

Tried "solution 1" in this guide Error: "VDI Not Available" (citrix.com)

 

/opt/xensource/sm/resetvdis.py single <VDI UUID>

 

Throws an error(See below), in the guide it says that " Use the VDI UUID from the error message or refer to the previous step. "

 

Traceback (most recent call last):
  File "/opt/xensource/sm/resetvdis.py", line 167, in <module>
    reset_vdi(session, vdi_uuid, force)
  File "/opt/xensource/sm/resetvdis.py", line 103, in reset_vdi
    {"vdiUuid": vdi_uuid, "srRef": vdi_rec["SR"]})
  File "/usr/lib/python2.7/site-packages/XenAPI.py", line 254, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib/python2.7/site-packages/XenAPI.py", line 150, in xenapi_request
    result = _parse_result(getattr(self, methodname)(*full_params))
  File "/usr/lib/python2.7/site-packages/XenAPI.py", line 228, in _parse_result
    raise Failure(result['ErrorDescription'])
XenAPI.Failure: ['HOST_OFFLINE', 'OpaqueRef:<Number>']

Im a little bit lost now, any help please :) ?

If you can see the vdi's on storage I would disconnect the disks from the VM's and reattach them 

then see if the VM's will start on another host in the pool until you fix this one. It appears this

host may be in emergency mode.

Hi,

 

That did unfortunately not work,

I managed to solve it with this guide: https://www.serveroperations.net/citrix/start-a-xenserver-vm-that-throws-vdi-not-available-error-when-you-attempt-to-start
