Environment: VSphere ESXi 6.7 on HP DL 380 (Single Server)

Problem: The VM’s getting hanged / frozen. Cannot Login to Windows nor issue any Power off commands. During the investigation , we found out that the VM’s were recording Event ID 129 with the Warning message “Reset to device, \Device\RaidPort0, was issued” , just before the VM becoming unresponsive.

We were referring the VMware KB https://kb.vmware.com/s/article/2063346 , and confirmed the LSI_SAS driver is updated to the latest version. But , luckily in our case , this deployment was a temporary one as we are planning to move this VM’s to a stable VSphere Cluster running on Nutanix. After few days ,moving the VM’s to the Nutanix environment , we noticed that the VM’s were functioning well with out any issues.

So for those who are having a similar issue , you need to check the underlying storage structure . As it could cause similar issues like this.

NOTE: During this unresponsive state , you could notice the Disk Latency stays at more than 20. This definitely a problem for a VM’s responsiveness.
