ESXi NMP Device State In Doubt Errors

Hi,

Recently been receiving errors on our ESXi server under the vmkwarning.log:

WARNING: NMP: nmp_DeviceRequestFastDeviceProbe:237: NMP device state in doubt; requested fast path state update...

Anyone able to provide any insight to these errors?

Regards,

David.

"This article explains why you may see the state in doubt; requested fast path state update messages in the /var/log/vmkernel log file and what the message means."

"These messages appear as the Host Bus Adapter (HBA) driver aborts a command because the command took longer than the timeout period of 5 seconds to complete."
