     > **Note**: This issue also applies to UCP 3.0.x and 3.1.x.
 
+- iSCSI on Kubernetes doesn't work on SLES15
+    - Workaround: use a swarm service to deploy this change across the cluster as follows:
+  1. Install UCP and have nodes configured as swarm workers.
+  2. Perform iSCSI initiator related configuration on the nodes 
+      - Install packages: 
+        ```
+        zypper -n install open-iscsi
+        ```
+      - Modprobe the relevant kernel modules 
+        ```
+        modprobe iscsi_tcp
+        ```
+      - Start the iscsi daemon 
+        ```
+        service start iscsid
+        ```
+
+   3. Create a global  docker service that updates the dynamic library configuration path of the ucp-kubelet with relevant host paths.         For this, use the UCP client bundle to point to the UCP cluster and run the following swarm commands: 
+        ```
+        docker service create --mode=global --restart-condition none --mount   type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock mavenugo/swarm-exec:17.03.0-ce docker exec ucp-kubelet "/bin/bash" "-c" "echo /rootfs/usr/lib64 >> /etc/ld.so.conf.d/libc.conf && ldconfig"
