Hello!
I created a new infrastructure:
2 hosts at the moment (ESXi 6.5.0-5146846), e.g. ESXi_1 and ESXi_2;
1 VCSA with external PSC;
AllFlash vSAN 6.6, multicast mode;
NFS-storage for infrastructure VMs;
dvSwitch prepaired for vSAN stretched cluster.
vmk configurations:
vmk0 is in management VLAN, MTU 1500, only management is enabled;
vmk1 is in vSAN VLAN, MTU 9000, only vSAN is enabled;
vmk2 is in vMotion VLAN (169.254.2.0/24), MTU 1500, only vMotion is enabled.
These hosts are in the same networks as the parallel infrastructure which works normally. vdSwitch configuration was imported from parallel infrastructure (because it is the tech.refresh of "old" parallel infrastructure)
Pings pass between this hosts including "vmkping -I vmk2" command.
If I try to migrate a running VM between hosts (compute resources changing only), an error "Unable to prepare migration. Network address ESXi_2 is not valid for migration." occurs.
The error occurs both when I try to migrate a VM to host ESXi_2, or when I try to migrate from ESXi_2. If I try to migrate a powered-off VM between hosts (compute resources changing only), an error doesn't occurs, vMotion passed.
Any considerations?
