Table Of Affected Software And Replacement Solution
UCS version 2.0(1m)
List of Affected Platform(s) for above software:
Cisco Unified Computing System (UCS)
Reason for Advisory:
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.
Headline: The show mac address-table aging-time vlan x command or running an SNMP agent querying this SNMP object causes an unexpected reboot.
Description: When a system is running UCS version 2.0(1m), the Fabric Interconnect may crash and reboot if either the NX-OS CLI ‘show mac address-table aging-time vlan x’ is issued, or the dot1dBridge MIB object (OID - 126.96.36.199.188.8.131.52.2) is being queried by SNMP.
In order to increase availability, Cisco recommends that you upgrade affected images with the suggested replacement software images. Cisco will discontinue manufacturing shipment of affected images. Any pending order will be substituted by the replacement software images.
PLEASE BE AWARE THAT FAILURE TO USE TO USE THE UPGRADE PROCESS MAY RESULT IN DOWNTIME.
The terms and conditions that governed your rights and obligations and those of Cisco, with respect to the deferred software will apply to the replacement software.
