XenServer 6 – Deleting a Storage Repository From the Command Line

8-inch-floppy-disks

So before we get started deleting a Storage Repository, we need to know a few key terms.

In XenServer a Storage Repository is a storage target that contains virtual disks (VDIs) and isos.

A PBD (physical device block) is what they call the interface between a physical host and an attached SR, which is responsible for storing the device config that allows the host to interact with the storage target.

So now that we have gotten that out of the way, lets get started.

First list the SRs on a host.

#xe sr-list uuid=9a9e7903-7c0f-4f7e-f0a3-e39c54478346

Using the uuid from the you got from the command above, run the command below using the UUID, which for some reason you are calling the sr-uuid.

#xe pbd-list sr-uuid=9a9e7903-7c0f-4f7e-f0a3-e39c54478346

uuid ( RO) : a89b78ca-cb3d-0b44-5d0b-9cf2c8ad755a
host-uuid ( RO): 4a9971f7-1e59-4e02-b849-04d206ee7b2b
sr-uuid ( RO): 9a9e7903-7c0f-4f7e-f0a3-e39c54478346
device-config (MRO): device: /dev/disk/by-id/edd-int13_dev81
currently-attached ( RO): true

Now using the the UUID output of from the command above, unplug the pdb.

#xe pbd-unplug uuid=a89b78ca-cb3d-0b44-5d0b-9cf2c8ad755a

Then destroy it….boom.

#xe pbd-destroy uuid=a89b78ca-cb3d-0b44-5d0b-9cf2c8ad755a

Now tell Xenserver to “forget” the SR.

#xe sr-forget uuid=9a9e7903-7c0f-4f7e-f0a3-e39c54478346
