Modify the usbmount.bat script
1. Using a text editor such as Notepad, edit the usbmount.bat script according to your requirements. The following attributes must be set:
2. Set the username, password and address (IP or hostname) of your XenServer host:
SET XE_USERNAME=root
SET XE_PASSWORD=CHANGEME
SET XE_SERVER=xxx.xxx.xxx.xxx
3. Determine the universally unique identifier (UUID) of the Storage Repository that corresponds with the Removable Storage. You can determine this by running the following command from within your XenServer host console:
xe sr-list name-label=Removable\ Storage
4. Once you have the UUID of the Removable Storage, make the change to the script:
REM Removable Storage Repository UUID
SET REMOVABLE_SR_UUID=CHANGEME
5. Determine the UUID of the virtual machine (VM) you wish to attach the storage to. To do this, run:
xe vm-list
6. With the UUID of the VM, make the change to the script:
REM UUID of the VM you wish to attach the USB storage to
SET VM_UUID=CHANGEME
7. Set the device order. It is important to ensure that there is no overlap and this is done by looking at the number of devices attached to the VM. For example, if only one storage device is currently being used (example: virtual hard disk), the next device name to use will be hdb.
REM Device name/order on the VM (example: hdb, hdc, hdd…)
SET DEVICE_NAME=hdb
8. Run or Schedule the Batch Program
9. Once you have made the changes to the batch program, test it by running it from a Command Prompt window. Note that the utility requires a parameter, otherwise it exits.
10. To attach the USB storage device to the VM, run:
usbmount.bat ATTACH
11. To detach the USB storage device from the VM, run:
usbmount.bat DETACH
