Online resize virtual machine disks on Xenserver or Xen

I try to increase vitrual disk on running Xen VM.

I use command xe vdi-resize uuid=a68471c4-e4f6-4e8f-9cde-74cba33d67d1 disk-size=13GiB online=true

where a68471c4-e4f6-4e8f-9cde-74cba33d67d1 is uuid of my xen guest VM.

I try to increase disk size on running VM, but I have a error:

The SR backend does not support the operation (check the SR's allowed operations) sr: e062ce43-056b-1044-02af-00fd6c8dc028 (iSCSI virtual disk storage)

I use iSCSI virtual disk storage

What I do wrong?

I use latest Xenserver version/

Has the Xenserver online disk resize feature?

Thanks in advance!

Solution

You're not supposed to give the uuid of the VM, you should be using the uuid of the disk you're trying to resize...

xe vm-disk-list vm="myVM"

Disk 0 VBD:
uuid ( RO)             : 0b1c2c6a-280b-68fd-dd8d-fb1c42f2ab80
    vm-name-label ( RO): myVM
       userdevice ( RW): 0


Disk 0 VDI:
uuid ( RO)             : 7b8df1e0-2f0c-4176-44a7-6fa94c42c4fa
       name-label ( RW): myVM 0
    sr-name-label ( RO): Netapp
     virtual-size ( RO): 32212254720

7b8df1e0-2f0c-4176-44a7-6fa94c42c4fa is the uuid you need to give to the vdi-resize command.
