[Xen-users] failure("Storage_access failed with: SR_BACKEND_FAILURE_47: [ ; The SR is not available

[Mike Lyon <mike.lyon@xxxxxxxxx>]

Hello,

Please excuse my complete xen ignorance but I am hoping someone will be able ot help me out here. I recently built my first Xen box using a 2, 1TB drives in a raid configuration, 2TB total.

I installed Xen, I am able to access it via XenCenter. However, I am trying to use some of that 2TB as a local datastore but for the life of me I cannot get it mounted, I keep on getting this error:

[root@xen1 dev]# xe pbd-plug uuid=6f3aa3c9-cd9e-adc6-c164-00655e6fe154

The server failed to handle your request, due to an internal error.  The given message may give details useful for debugging the problem.

message: Failure("Storage_access failed with: SR_BACKEND_FAILURE_47: [ ; The SR is not available [opterr=no such volume group: VG_XenStorage-46d633a8-2d98-03a8-3203-64e2f0e14f2b];  ]")

The steps I followed was this:

Here is exactly what I did:
