This object records whether this virtual-context row's configuration is stored persistently across reboots, such as nonVolatile, or only transiently in memory, such as volatile, and per the description a row marked permanent need not even allow its columns to be edited. It matters because an admin troubleshooting why a virtual context configuration disappeared after a reload needs to check this value first; a volatile storage type row is expected to vanish on reboot by design, not due to a fault. Seeing volatile here on a production context that is supposed to survive reloads would point straight at a provisioning mistake rather than a hardware issue.
