VSAN upgrade from 6.7 u1 to 6.7 u3

[ManivelR]

Hi All,

I have some packet drops issue on vSphere 6.7 u1 ESXi hosts. As this is known issue on 6.7 U1,we like to go with vSphere 6.7 u3.

As this is VSAN environment and having 6 hosts, we like to upgrade to 6.7 U3 on only one esxi host(lets say ESXi01) at this point of  time to conclude this issue.

vCenter server version is 6.7 U1

ESXi version is 6.7 U1.

As per the above matrix,we can update the ESXi host directly to 6.7U3 without updating vcenter server 6.7 U3.Is this right?

But again the best practices is given below and we can follow the procedure later starting from vcenter server upgrade to 6.7 U3(after above ESXi01 upgrade)

1) Update first vcenter server from 6.7 U1 to 6.7 U3.

2) Follow the below instructions to complete the VSAN upgrade without any issue.

Hello Raj,

"As this is VSAN environment and having 6 hosts, we like to upgrade to 6.7 U3 on only one esxi host(lets say ESXi01) at this point of  time "

As this is a vSAN cluster, you should be updating the whole cluster and not just one host.

"As per the above matrix,we can update the ESXi host directly to 6.7U3 without updating vcenter server 6.7 U3.Is this right?"

No, this is not right as you have selected the incorrect product (ESXi, not vSAN) - updating vCenter to 6.7 U3 before the hosts is required:

Sure, Hareesh's guide there is fine.
