While checking the logs for the VM DBO_S4 (on the node: minicloud03) at
/var/parallels/DBO_S4.pvm/parallels.log, I found the following information:
--
/vdisk:7186:7195/ Error locking file
/var/parallels/DBO_S4.pvm/harddisk.hdd/harddisk.hdd [0]
05-21 11:59:21.841 F /vdisk:7186:7195/ Couldn't lock disk: 0x80021014
05-21 11:59:21.841 F /vdisk:7186:7195/ OpenDisk() returned error 0x80021014
05-21 11:59:21.842 F /ioctl:7186:7195/ descr 24 reopened to be 102399

I tried to find out the HDD atached to it:
--
[root@minicloud03 DBO_S4.pvm]# lsof 2>/dev/null | grep hdd
prl_vm_ap 7186 root 41uW REG 0,21 0
