VSAN 6.0 - VMs freeze after host failure

Hi everyone!

We are facing a problem when a host in a VSAN cluster fails, the virtual machines simply freezes.  Linux OS normally turn filesystems to read only, Windows OS stop respond.

bellow some information about environment:

• 2 x Clusters (1 x 10 hosts / 2 x 20 hosts);
• Host: HP DL380 Gen 9;
• Storage Controller: HP Smart HBA H240ar;
• 4 x SSD Disk 400GB eMLC + 20 x SAS Disk 1.2 TB, per host;
• 2 x 10GB (LACP + MTU 9000 + Multicast) to VSAN + 2 x 10GB (LACP) to LAN, per host;
• VMware ESXi, 6.0.0, 2715440

Any help?

Thanks,

CH
