This article describes how to set LUNs on a target to Read Only via Configuration Manager.
If you want to move a Storage from one VRM to another, this procedure is needed in Order to retain your video footage until the desired Retention Time is over.
All you need is the Configuration Manager on a PC in the same Network as the VRM.
If you don’t have the Configuration Manager, you can download it here.
Please be aware that setting the LUNs to Read only will decrease the Capacity of the VRM,
which might lead to a lower Minimum Retention Time then desired.
Calculate upfront, if the available Storage is enough!
