Hi all,
to remove lock I found this script:

"
/[root@ovirt-new dbutils]#  ./unlock_entity.sh  -t disk 
01f9b5f2-9e48-4c24-80e5-dca7f1d4d128//
//Caution, this operation may lead to data corruption and should be used 
with care. Please contact support prior to running this command//

//Are you sure you want to proceed? [y/n]//
//y//
//select fn_db_unlock_disk('01f9b5f2-9e48-4c24-80e5-dca7f1d4d128');//

//INSERT 0 1//
//unlock disk 01f9b5f2-9e48-4c24-80e5-dca7f1d4d128 completed successfully.//
"

/
but virtual disk is still lock.
