Manager (VUM)
Upgrading from Dell EMC customized ESXi 6.5.x host to Dell EMC customized ESXi 7.0 A01 using VUM
might fail when one of the below Converged Network Card is present in the system with FCoE or iSCSI
enabled. Upon invoking upgrade, the system fails to boot and reports the following error message during the
reboot cycle post upgrade:
Fatal error: 15 (Not found)
Following are the impacted NIC:
• Qlogic 51xxx series cards
• Qlogic 41xxx series cards
• Emulex OneConnect OCM14xxx Series of cards
Note: This specific issue is resolved in Dell EMC ESXi 7.0 A02 image. For more information, see VMware

2.8 Upgrading from Dell EMC customized versions installed with stand-
alone tools & utilities
Dell EMC provides the below stand-alone tools & utilities supported for ESXi release. These utilities & tools
can be installed with ESXi.
• PERCCLI
• Dell EMC iDRAC Tools
The following are specific to stand-alone tools and utilities:
• All these packages are available at Dell support page for various ESXi releases.
• Dell EMC utilities and tools are not migrated to 64-bit user world.
• These tools and utilities are not bundled with the Dell EMC custom-ISO releases.
Use the following commands to remove PERC CLI and Dell EMC iDRAC tools VIB:
• esxcli software vib remove -n vmware-perccli
• esxcli software vib remove -n racadm
It is required to uninstall the respective VIBs from vSphere 6.x versions prior attempting to upgrade, failing to
do this and attempting to upgrade results in a failure mentioned in the following screenshot.
Below is a snapshot indicating the specific upgrade error when the standalone utility packages are installed
on 6.x branch of ESXi prior performing 7.0 upgrade.
