Bug ID
Description

Table 3 Open Caveats

Bug ID
Description

CSCuj20256

Cisco - OEM - USER_MODE_HEALTH_MONITOR (0x9e) BSOD with Ethernet and FC traffic on VMs.

CSCul57107

Environments that have storage fabric errors (in a SAN or array) that result in the array sending sustained LOGO messages and that are using the Cisco VIC adapter might experience errors and loss of connectivity to the storage that requires a manual reset of the vHBA in UCS.

Customers using Red Hat Enterprise Linux version 5.8 or an earlier version should be aware that a libfc bug exists in distributions. The details of this bug are available in the Red Hat Bugzilla 884740.

Known Limitations and Behaviors

The following limitations were introduced with support of ARFS in Cisco UCS Manager release 2.2(2c):

  • Supported only on UCS-VIC-M82-8P and UCSB-MLOM-40G-01.
  • Supports 64 flow classifier entries per vNIC.
  • Supports approximately 992 flow classifier entries per adaptor (approximately 15 vNICs with ARFS enabled).

The following limitations were introduced with support of AIC in Linux ENIC driver in Cisco UCS Manager release 2.2(2c):

  • Does not provide any advantage when the link utilization is greater than 80%.
  • When enabled, this feature disables static coalescing.

The following limitations were introduced with support of NetQueue in Cisco UCS Manager release 2.2(2c):

  • VMware recommends no more than 8 NetQueues per port for standard or jumbo (9000) frame configurations.

When enabling NetQueue on vNICs, Cisco recommends using the default VMware adapter policy.

Enabling too many NetQueues on too many vNICs can result in the host exceeding limits for netPKtheap and msix interrupts.

  • NetQueue should be enabled only for vNICs configured to use MSI-X interrupts.
  • VMware recommends disabling NetQueue for 1G NICs.
