When adding new storage repository on XenServer 5.5 you get the following error: Creating SR No such device Solutions Restart all the XenServer host and add the new storage repository again.

1. Find the UUID for the host you want to remove. # xe host-list 2. Remove the host. Use the UUID from step 1, in this example the UUID is xxxx-xxxx-xxxx-xxxx-xxxx # xe host-forget uuid=xxxx-xxxx-xxxx-xxxx-xxxx
