Checking some logs I've found that my storagerm logs are full of those kind of messages. My esx hosts are all up and running. I'm running on ESX 5.5U2 on NetApp (Ontap 8.2.1) NFS datastore with SIOC enabled.
I've read that a solution is to disable/reenable SIOC and I've dont it but it seems that I'm still full of such messages:
If this message in not useful there's any way to disable it (I've checked on the advanced option and the Misc.SIOControlLogLevel is already 0 so why I get those logs?)?
This is just an example:
