Release date: July 26, 2018

Summaries and Symptoms

This patch updates the esx-base, vsan and vsanhealth VIBs to resolve the following issue:

• During an ESXi boot, if the commands issued over the initial device discovery fail with ASYMMETRIC ACCESS STATE CHANGE UA, the path failover might take longer because the commands are blocked within ESXi. This might lead to longer ESXi booting.

  You might see logs similar to:

• You might see the Presence sensors in the Hardware Status tab of the vSphere Web Client displaying a status Unknown. This fix filters out only the Presence sensors that are not in a valid health state.

• An ESXi host might fail with a purple diagnostic screen due to a race condition in a query by the Multicast Listener Discovery (MLD) version 1 in IPv6 environments. You might see an error message similar to:

  #PF Exception 14 in world 2098376:vmk0-rx-0 IP 0x41802e62abc1 addr 0x40

• APIs for Storage Awareness (VASA) providers might not be available due to missing namespaces such as SERIALNUM and NAA in the ScsiLunDurableName property.

The typical way to apply patches to ESXi hosts is through the VMware vSphere Update Manager. For details, see the Installing and Administering VMware vSphere Update Manager.
