Hello Mhmood Hamooda,To remove the persistent reservation Reserve you will need to run the following command from SMCLI: Clear virtualDiskName1 reservations The virtual disk name1 is the name that you gave that virtual disk in MDSM.  You can run the same command on all virtual disk by changing the name to allVirtualDisks.  Here is also a link to SMCLI as well just in case you don’t have it already.
