Please try:

How do I map spUUID, sdUUID and imgUUID ? 



OK, thanks.
In my case even after detaching and removing the original SD and putting the target SD (now the only attached to the DC) into maintenance, putting host into maintenance and rebooting the host, I still get these old LVs with flags ao (san visibility to the old source sd is still here... I'm going to remove when cleaned up..).

Could it depend on the fact that there was another host in the DC that I put into maintenance and then powered off (because at the moment only one host was able to see the target SD where I moved all the disks)?
So a sort of retained lock?

Anyway after restarting this host and activating it with also 2 running VMS I have this kind of LV situation related to disks.
Note that I also included vg_name and you can see 3 VGs

be0c72ca-2dbc-4e02-ab48-5491ea0c01b7 and  f7b481c8-b744-43d4-9faa-0e494a308490 are two VGs on source old storage domains from where I moved disks

c0097b1a-a387-4ffa-a62b-f9e6972197ef is VG on target new storage domain where I moved the disks

So there are on the two old VGs some "remove_me" tagged LVs... that I think corresponds to the erorrs I got during move disk operations

And if I take as reference the 6d23ec3e-79fb-47f0-85ff-08480476ea68 related LV, I get these two entries

c0097b1a-a387-4ffa-a62b-f9e6972197ef 6d23ec3e-79fb-47f0-85ff-08480476ea68 IU_8eb435f3-e8c1-4042-8180-e9f342b2e449,MD_9,PU_00000000-0000-0000-0000-000000000000            
f7b481c8-b744-43d4-9faa-0e494a308490 6d23ec3e-79fb-47f0-85ff-08480476ea68 IU__remove_me_8eb435f3-e8c1-4042-8180-e9f342b2e449,MD_14,PU_00000000-0000-0000-0000-000000000000

Of course the one with "remove_me" inside tag is what I have to remove... because it is on old source SD that now has been detached/removed.

what should it be the imgUUID value to give to vdsClient? Do I have to include IU prefix or what?

The first part of the command should be 

vdsClient -s 0 teardownImage 55c7e1ee-7246-4574-ba46-28d4582ba0e8 f7b481c8-b744-43d4-9faa-0e494a308490  ..... 

Thanks again.
