look for SMcli.exe underneath one of the Dell directories.  It should have been referenced in the manual where you found that command. 
Hello,  I am testing a MD3620i  in our environment. I had setup up some virtual disks thru MDSM. I mapped one of the virtual disk thru to two hosts Now when i try to change the mapping of the disk i am getting a error "Error 219 - The operation cannot complete because the virtual disk has a persistent reservation placed on it. Please release the reservation at the host and then retry the operation" Is there a way to release this thru the GUI ? I found a command " clear (allVirtualDisks | virtualDisk[virtualDiskName] | virtualDisks [virtualDiskName1" ... "virtualDiskNamen]) reservation " on the dell documents but i am not sure how i get access to the CLI ? when i go thru the resource CD it didnt have any CLI option to install Thank you
Need help Getting Started with CLI for MD3620i
