Is there any possible risk to a workload if I disable SIOC on an RDM LUN while the RDM LUN is in use? It was previously mistakenly enabled.
There is NO impact only that SIOC functionality will not be available which distribute IOPS across VMs in case there is IO contention based on IOPS shares set on each VM placed on DS. . Plz let me know your vSphere VC/ESXi version. We need to check if SIOC is supported with RDM. Stay tuned for some more details.
