This enumerated field shows whether DIMM blacklisting is actually active for this specific server's memory, as opposed to the policy-level setting that merely configures the intent. An admin comparing this instance-level field against the policy field of the same name can confirm whether the configured policy actually took effect on this particular blade, or whether it's still pending a reboot/BIOS re-negotiation. If a service profile's policy enables blacklisting but this per-server field still shows disabled, that mismatch tells the admin the setting hasn't been applied to the running hardware yet.
