vCenter5.0不兼容ESXi4u2！！！

TiGi

ESXi 4.0 Update 2 hosts may experience a purple screen after vCenter Server is upgraded to 5.0
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.

ESXi 4.0 Update 3 and later versions can be downloaded from the vmware Download Center.
