Cause
SIOC is not supported on VMFS datastores that are constructed from multiple LUNs. This is because only a single LUN holds the metadata for the entire datastore and that is the only LUN that is monitored for failure. If any other LUN goes down, SIOC will be unaware of this change.This can also occur if the same LUN is presented to the ESXi hosts in the cluster with different LUN IDs.
Resolution
1. Verify if the VMFS datastore where we are attempting to enable SIOC is not a multi-extent datastore.2. Avoid same LUN presentation to the ESXi hosts in the cluster with different LUN IDs.
