Table 8‑1. Error and Warning Codes That Are Returned by the Installation and Upgrade
Precheck Script (Continued)
Error or Warning Description
DISTRIBUTED_VIRTUAL_SWITCH If the Cisco Virtual Ethernet Module (VEM) software is found on
the host, the test checks that the upgrade also contains the VEM
software. The test also determines whether the upgrade
supports the same version of the Cisco Virtual Supervisor
Module (VSM) as the existing version on the host. If the software
is missing or is compatible with a different version of the VSM,
the test returns a warning. The result indicates which version of
the VEM software was expected on the upgrade ISO and which
versions, if any, were found. You can use
ESXi Image Builder CLI to create a custom installation ISO that
includes the appropriate version of the VEM software.
HARDWARE_VIRTUALIZATION Warning. If the host processor doesn't have hardware
virtualization or if hardware virtualization is not turned on in the
host BIOS, host performance suffers. Enable hardware
virtualization in the host machine boot options. See your
hardware vendor's documentation.
MD5_ROOT_PASSWORD This test checks that the root password is encoded in MD5
format. If a password is not encoded in MD5 format, it might be
significant only to eight characters. In this case, any characters
after the first eight are no longer authenticated after the
upgrade, which can create a security issue. To work around this
problem, see VMware knowledge base article 1024500.
MEMORY_SIZE The host requires the specified amount of memory to upgrade.
PACKAGE_COMPLIANCE vSphere Update Manager only. This test checks the existing
software on the host against the software contained on the
upgrade ISO to determine whether the host has been
successfully upgraded. If any of the packages are missing or are
an older version than the package on the upgrade ISO, the test
returns an error and indicates which software was found on the
host and which software was found on the upgrade ISO.
PARTITION_LAYOUT You can upgrade or migrate software only if at most one VMFS
partition on the disk is being upgraded and the VMFS partition
must start after sector 1843200.
POWERPATH This test checks for installation of EMC PowerPath software,
consisting of a CIM module and a kernel module. If either of
these components is found on the host, the test checks that
matching components,such as CIM, vmkernel and module, also
exist in the upgrade. If they do not exist, the test returns a
warning that indicates which PowerPath components were
expected on the upgrade ISO and which, if any, were found.
PRECHECK_INITIALIZE This test checks that the precheck script can be run.
SANE_ESX_CONF The /etc/vmware/esx.conf file must exist on the host.
SPACE_AVAIL_ISO vSphere Update Manager only. The host disk must have enough
free space to store the contents of the installer CD or DVD.
