This important notice just came across my radar:

VMware has become aware of some ESXi 4.0 hosts experiencing a purple screen after vCenter Server is upgraded to 5.0

The Knowledgebase Team has prepared KB article: ESXi 4.0 Update 2 hosts may experience a purple screen after vCenter Server is upgraded to 5.0 (2007269) and an alert has been placed on the Support page to alert customers of this issue.

Symptoms

You may encounter an issue where:

  • You have recently upgraded your vCenter Server to version 5.0
  • You have ESXi 4.0 Update 2 hosts in the inventory of this vCenter Server
  • After the vpxa agents are upgraded, the ESXi 4.0 Update 2 hosts experience a purple screen that includes this error:NOT_IMPLEMENTED bora/vmkernel/filesystems/visorfs/visorfsObj.c:3391

Cause

This is caused by an issue in the handling of the vpxa agent upgrade.

Resolution

This issue has been resolved in 4.0 Update 3. To avoid this issue, upgrade all ESXi 4.0 Update 2 hosts to at least version ESXi 4.0 Update 3 before upgrading vCenter Server to 5.0.

    From what I’ve been able to discover so far, this does not affect any releases earlier than Update 2 so if you’re still at update 1 or earlier, you’re apparently safe from this bug.

    Jason, thanks for the heads up! We were thinking about testing out VS5 as we have a need for >2TB LUN support for a file server VM and this bug would have affected us, we’ll be upgrading to U3 before we put VS5 into the dev/test cluster =)

  3. Hey Jason,
    Thanks for the FYI! Good to know as my current client is wanting to go vCenter 5.0 with ESXi 4.1 update 1 on the server.
