Release Notes for Cisco UCS Manager, Release 2. Firmware Upgrade Checks the VIF/Interface Status After Fabric Interconnect Reboot—During firmware upgrade, to ensure proper functioning of all services on the fabric interconnect, it is essential to ensure that port configurations and services that go down when the fabric interconnect reboots are re- established after the fabric interconnect comes back up. Cisco UCS Manager displays any service that is not re- established after the last reboot of a fabric interconnect. NIC Redundancy Pair— Supports two v. NICs/v. HBAs that are being configured with a common set of parameters through the v. NIC/v. HBA template pair. This prevents the configuration between two v. This document describes system requirements, new features, resolved caveats, known caveats and workarounds for Cisco UCS Manager software Release 2.2. NICs/v. HBAs from going out of sync. Multiple v. NIC/v. HBA pairs can be created from the same v. NIC/v. HBA template pair. Ability to perform UCS Manager initial configuration without console connectivity based on DHCP lease availability. Preserving the following properties during backup or import operations: User- defined labels for Chassis, FEX, Rack Servers, IOMs and Blade Servers. Assigned IDs for Chassis, FEX and Rack Servers Locator LED support for server hard- disks—You can now identify where a specific disk is inserted in a blade or rack server using the local locator LED. When you add new servers or adapters to an existing Cisco UCS system with a Cisco UCS Manager release that does not support these servers and adapters, discovery of the system may fail. In case of such a failure, the FSM will display an error message that the server or adapter is not supported on the current UCS firmware version. To resolve this issue, do one of the following: Update the Capability Catalog to the latest compatible release. Upgrade the Cisco UCS Manager infrastructure firmware to the version required by the new hardware. Provision to Reset Peer I/O Modules to Factory Defaults—Sometimes, I/O module upgrades can result in failures or I/O modules can become unreachable from Cisco UCS Manager due to memory leaks. You can now reboot an I/O module that is unreachable through its peer I/O module. Resetting the I/O module restores the I/O module to factory default settings, deletes all cache files and temporary files, but retains the size- limited OBFL file. NIC template CDN Source—Enables you to select the Consistent Naming Device (CDN) Source as the v. NIC Name, which in turn can either be customized or derived from the v. NIC instance. NVMe PCIe SSD Inventory—Cisco UCS Manager discovers, identifies, and displays the inventory of Non- Volatile Memory Express (NVMe) Peripheral Component Interconnect Express (PCIe) SSD storage devices. You can view the health of the storage devices in the server. NVMe with PCIe SSD storage devices reduce latency, increase input/output operations per second (IOPS), and lower power consumption compared to SAS or SATA SSDs. PCH SSD Controller Definition—Cisco UCS Manager Platform Controller Hub (PCH) Solid State Drive (SSD) Controller Definition provides a local storage configuration in storage profiles where you can configure all the disks in a single RAID or in a JBOD disk array. Host Firmware Package Enhancement—You can now exclude firmware of specific components from a host firmware package either when creating a new host firmware package or when modifying an existing host firmware package. For example, if you do not want to upgrade RAID controller firmware through the host firmware package, you can exclude RAID controller firmware from the list of firmware package components. Local disk firmware is excluded from the host firmware package by default. Installed Firmware Tab Enhancement—The Installed Firmware tab now displays all the firmware available on the blade server, including SAS controller firmware, Flex. Flash controller firmware, and Disk firmware. Provision to suppress VIF down alert—When a blade server that is associated with a service profile is shut down, the VIF down alert F0. F0. 47. 9 are automatically suppressed. EFI Shell as a Boot Device—You can create a boot policy with an EFI Shell as the boot device. Booting from an EFI Shell prevents loss of data and provides more options to script, debug, and control various booting scenarios. EFI Shell is supported as a boot device only in the Uefi boot mode. Multicast Hardware Hash—In a port channel, by default, ingress multicast traffic on any port in the fabric interconnect (FI) selects a particular link between the IOM and the fabric interconnect to egress the traffic. To reduce potential issues with the bandwidth, and to provide effective load balancing of the ingress multicast traffic, hardware hashing is used for multicast traffic. When multicast hardware hashing is enabled, all links between the IOM and the fabric interconnect in a port channel can be used for multicast traffic. Reset All Memory Errors—Provides the ability to clear all the errors from the UCS Manager. CPLD Update of the UCSB- MRAID1. G Storage Controller—Starting with Cisco UCS Manager Release 2. CPLD component update. The CPLD update for the UCSB- MRAID1. G storage controller can be triggered by doing one of the following: Re- acknowledging the server—If the server did not go through a deep- assoc after upgrading to the Cisco UCS Manager 2. Updating the associated HFP with a supported B bundle—If the server was associated after upgrading to the Cisco UCS Manager 2. VM- FEX Support—Support for ESX VM- FEX added. The support matrix in the Hardware and Software Interoperability Matrix for this release provides more details. SHA- 2 Certificate Support—Support for SHA- 2 certificate added.
