Headline: PCI Device address changes after an upgrade from 1.4 to 2.0 release on VIC device
Description: When a system is upgraded from UCS 1.4 and earlier releases,  the PCI device address of existing Service Profile VNICs and VHBAs in case of VIC adapters changes. This can potentially cause certain OSes such as VMware ESX and Windows to see the old VNICs and VHBAs with new PCI addresses, which could result in those interfaces being non operable unless the configuration is changed in the OS.  In the case of ESX, a workaround would be to edit the esx.conf with the new PCI address and to modify the vswitch configuration.

Headline: B230-M1: PCI bus numbers change after an upgrade from 1.4 to 2.0

Description: When the BIOS is upgraded on a B230-M1 blade from UCS 1.4 to the 2.0 release, the PCI bus enumeration will shift by one bus number. This can potentially cause certain OSes such as VMware ESX and Windows to see the old VNICs and VHBAs with new PCI addresses, which could result in those interfaces being non operable unless the configuration is changed in the OS.  In the case of ESX, a workaround would be to edit the esx.conf with the new PCI address and to modify the vswitch configuration.

CSCtr74091 (for version 2.0 and all future releases when upgrading from any 1.x UCS release)

Headline: Overlapping FCOE VLAN and Ethernet VLANs no longer allowed with UCS 2.0

Description: In 1.4 and earlier releases, overlapping ids were allowed for Ethernet VLANs and FCOE VLANs. Starting with UCS release 2.0, this is not allowed and a critical fault will be raised on upgrade if overlapping ids exist. Users should ensure that the VLAN ids are not overlapping before attempting the upgrade.
