vSphere Storage• -L lunreset – Resets the specified LUN by clearing any reservation on the LUN and making the LUNavailable to all servers again. The reset does not affect any of the other LUNs on the device. If anotherLUN on the device is reserved, it remains reserved.• -L targetreset – Resets the entire target. The reset clears any reservations on all the LUNs associatedwith that target and makes the LUNs available to all servers again.• -L busreset – Resets all accessible targets on the bus. The reset clears any reservation on all the LUNsaccessible through the bus and makes them available to all servers again.When entering the device parameter, use the following format:/vmfs/devices/disks/disk_ID:PBreaking Device LocksThe -B option allows you to forcibly break the device lock on a particular partition.-B --breaklock deviceWhen entering the device parameter, use the following format:/vmfs/devices/disks/disk_ID:PYou can use this command when a host fails in the middle of a datastore operation, such as grow extent,add extent, or resignaturing. When you issue this command, make sure that no other host is holding thelock.268 VMware, Inc.
