Verify all paths are clean; address any CRCs or similar errors. Users must ensure that the iSCSI initiator is already configured on all OpenShift Container Platform nodes by installing the iscsi-initiator-utils package and configuring their initiator name in /etc/iscsi/initiatorname. Enable CHAP: 3 CHAP will require iSCSI Initiators to be authenticated before using the iSCSI. It includes the rbd-target-api daemon which is responsible for restoring the state of LIO following a gateway reboot/outage and exporting a REST API to configure the system using tools like gwcli. 000R. iSCSI is a block level protocol, which means it's pretending to be an actual physical hard drive that you can install your own filesystem on. iSCSI. 0 today, support is provided for the versions above 3.

However, there are Kubernetes data management problems that CSI does not currently tackle. IBM Publications Center website. For example, for a job that needs an AWS EBS volume, Nomad will tell the controller plugin that it needs a volume to be "published" to the client node, and the controller will make the API calls to AWS to attach the EBS volume to the right EC2. Why use iSCSI Manager? Easily create and manage different type of LUN. External CSI Controllers is a deployment that deploys one or more pods with three containers: An external CSI attacher container translates attach and detach calls from OpenShift Container Platform to respective ControllerPublish and ControllerUnpublish calls to the CSI driver. Select iSCSI, then select Add to create a new target. CSI drivers are typically shipped as container images. 9. k8s. I've read post number 22098 where it's very well explained how to create iScsi initiator. Next step consists in creating the first LUN (which will be served by the RAID 10 in my case). 5. A container, such as CSI node plugins, can mount the named pipes depending on operations it wants to exercise on the host and invoke the APIs. To connect to the new iSCSI Target on Windows, open the iSCSI Initiator app, go to the “Discovery” tab, and click on the “Discover Portal” button.
