Forcibly Remove Storage Devices From XenCenter via CLI

HammerbroThis is my second post in focused on forcibily something from XenCenter, as apparently XenCenter has a hard time knowing when to "forget" a device or host on its own. Now while this is annoying, it can be resolved rather easily from the command line.

Now, lets take a step back and reflect for a moment on the first post in this series… you can find it here. Anyway this first post showed us how to remove the orphaned device via the Windows CLI, however I find the process of using the CLI in Windows to be painful, so this post is going to outline a similar process but via the CLI on the XenServer host itself.

Anyway in the previous post I had to force remove a host from XenCenter via the CLI, and in this post I need to remove the "Local Storage", "Removable Storage" and "DVD Drive" that were associated with the orphaned host. These are the items in red below.

By clicking on each one of the items in XenCenter I can see that they are all in a Detached State, plus i can see the UUID of each item. You will need the UUID for the next step.

Now ssh into your master node and run the following

#xe sr-list

Look for the entry with the matching UUID

uuid ( RO)                : 64e69b7d-ae97-4d42-c4d8-c260553b31d1
name-label ( RW): Local storage
name-description ( RW):
host ( RO): <not in database>
type ( RO): lvm
content-type ( RO): user

Then run the following command to remove it from XenCenter Inventory

# xe sr-forget uuid=64e69b7d-ae97-4d42-c4d8-c260553b31d1

Now rinse and repeat for any remaining orphaned items.
