local disk Device performance has deteriorated. I/O latency increased

A local disk I / O deteriorated log appears.

There is no VM on the local disk

Why does the message appear on the local disk?

If these messages are repetitive on Shared storage then it indicates a performance issue and which impacts VM.

Here as you dont have VM's and It is a local disk that should not be a problem however just check on firmware version on safer side .
