When I use Host Update Utility to do the upgrading of ESXi 3.5 to 4.0, it said:
ERROR: Unsupported boot disk
The boot device layout on the host does not support upgrade.
When I use Update Manager, it said:
Failed to import upgrade.
Error was: Upgrade release not supported by this version of VMware vCenter Update Manager.
I
searched the forum and people advise upgrading VUM to 4.0u1. But I also
read that ESXi users do not upgrade vCenter to 4.0u1. So is it possible
to upgrade VUM to 4.0u1 without upgrading vCenter 4.0 to 4.0u1? Cause I
can't find VUM ISO at all and assume it must be included together with
vCenter ISO. Any solution?
