Enable XDC kernel mode on new storage nodes

Environment

• Product: ZCF
• Component: ZCE-X
• Affected objects: Newly added storage nodes, XDC, Ceph, and the Kylin kernel
• Version: 6.4.200.1
• Trigger condition: New storage nodes may connect to CSI-iSCSI in the future, so XDC kernel mode must be enabled during deployment.

Symptoms

• New storage nodes will connect to CSI-iSCSI in the future.
• XDC kernel mode must be enabled in advance on new primary-storage nodes that are not yet carrying workloads.
• The change applies only to new storage nodes and must not affect compute nodes.
