Hello Mulyadi, I am using ESX and sometimes I have to attach disks dynamically and remove them. I have caching solution installed on my machine, if I ever cache the attached disk, remove it, and attach a different disk, this newly added disk might accidentally be treated as original disk and might be cached incorrectly. Therefore, I wanted to ensure that every time a disk is attached it is named differently.
