VMware vSphere ESXi 6.0


Summaries and Symptoms

This patch resolves the following issue:

  • For vSAN All-Flash configurations with deduplication enabled you might see the following two vSphere Observations (VOBs) in the Events tab:
    "vSAN detected an unrecoverable medium or checksum error for component
    uuid on disk group uuid." and "vSAN detected and fixed a medium or checksum error for component uuid on disk group uuid."

    In addition, you might encounter IO read errors and in some cases severe symptoms such as inaccessible VMs, host failures, or stuck resyncs. The issue manifests itself only under highly specific operations and IO patterns.

    If you have seen the above messages, please call VMware Global Support Services immediately.

    Notwithstanding, all vSAN customers using All-Flash with deduplication enabled must upgrade to this patch release immediately.

Patch Download and Installation

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.

ESXi hosts can be updated by manually downloading the patch ZIP file from the VMware download page and installing the VIB by using the esxcli software vib command. Additionally, the system can be updated using the image profile and the esxcli software profile command. For details, see the vSphere Command-Line Interface Concepts and Examples and the vSphere Upgrade Guide.
