+# iSCSI Cleanup Reference
+
+This file contains the standard iSCSI target cleanup sequence for Linux guests used in CDS MCP workflows.
+
+## Scope
+- Use this reference when the user asks to clean up saved iSCSI targets on a machine.
+- This is a guest-level cleanup workflow and is separate from CMC install or CDC project cleanup.
+
+## Standard Sequence
+1. Log out of all current targets:
+
+```bash
+iscsiadm --mode node --logoutall=all
+```
+
+2. List saved node records and note the target IQN values:
+
+```bash
+iscsiadm -m node
+```
+
+3. Remove each target by IQN:
+
+```bash
+iscsiadm -m node -o delete -T <iqn>
+```
+
+4. Re-list nodes and confirm the list is empty:
+
+```bash
+iscsiadm -m node
+```
+
+## Notes
+- One IQN can appear on multiple portals; deleting by IQN removes the saved node records for that target.
+- `No records found` is an acceptable result if the machine is already clean.
+- Unless the user asks otherwise, perform the logout step before deleting saved node records.
