Cisco UCS Manager and Cisco UCS C-Series Release Compatibility Matrix for C-Series Rack-Mount Servers

Cisco UCS C-Series Rack-Mount Servers are managed by built-in standalone software— Cisco Integrated Management Controller (Cisco IMC). However, when a C-Series Rack-Mount Server is integrated with Cisco UCS Manager, the Cisco IMC does not manage the server anymore.

Each Cisco UCS Manager release incorporates its corresponding C-Series Standalone release. For example, Cisco UCS Manager Release 4.2(1) is integrated with C-Series Standalone Release 4.2(1) for the M6 servers, Release 4.1(1) for the M4 and M5 servers, Release 4.0(2) for all the M4 and M5 servers. Hence, it supports all the M6, M5 and M4 servers supported by C-Series Standalone releases.

The following table lists the Cisco UCS Manager and C-Series software standalone releases for C-Series Rack-Mount Servers:

If Cisco UCS Manager upgrade to release 4.2(1l) fails with Unable to open downloaded image error message, refer Open Caveats for Release 4.2(1l) for a workaround.

Upgrade Limitation

In general, capability catalog can be upgraded within the same major release version. For example, Cisco UCS 3.2(2) release can use a capability catalog with the same major release version like 3.2(1) and cannot use a capability catalog with the release version 3.0(1). However, the Capability Catalog upgrade from 4.2(1) to 4.2(2) can lead to upgrade failure. Cisco UCS release 4.2(1) release version can be used only with 4.2(1) release version of capability catalog.

UCS Manager Health and Pre-Upgrade Check Tool

The UCS Manager Health and Pre-Upgrade Check Tool provides automated health and pre-upgrade checks that are designed to ensure your clusters are healthy before you upgrade. It is imperative that this healthcheck is not just performed, but that you take corrective action on any cluster that is found to be unhealthy. Correct all issues reported by the UCS Manager health check before continuing.

CSCwk62264

Cisco UCS Manager includes Third-party Software that is affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) IDs:

  • CVE-2024-6387—A race condition has been identified in the sshd service related to its signal handler. If a client fails to authenticate within the LoginGraceTime period (default is 120 seconds, previously 600 seconds in older OpenSSH versions), the sshd SIGALRM handler is triggered asynchronously. This handler, however, invokes several functions that are not safe to call from within a signal handler, such as syslog().

The affected third-party software component has been upgraded to a version that includes fixes for the vulnerability. Future versions of the product(s) will not be affected by this vulnerability.

CSCwi59915

Cisco UCS Manager includes Third-party Software that is affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) IDs:

  • CVE-2023-48795—The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks, such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, also known as Terrapin attack.

    This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and use of sequence numbers. For example, when there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC), the bypass occurs in chacha20-poly1305@openssh.com, (and if CBC is used, then the -etm@openssh.com MAC algorithms).

The affected third-party software component has been upgraded to a version that includes fixes for the vulnerability. Future versions of the product(s) will not be affected by this vulnerability.

However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).

Currently, Cisco UCS Manager does not support a speed configuration of 40G for FCoE ports and sets the speed as auto.

Therefore, with a 40G transceiver, FCoE uplink port and Port channel go into Admin State down state. Cisco UCS Manager is unable to match the speed configuration with the upstream switch speed of 40G.

Ensure that the speed is set as Auto and Auto Negotiation is set to ON on the upstream switch side.

Cisco UCS 6300 series FI migration to Cisco UCS 6536 FI connected to UCS-IOM-2304 may take longer than expected (up to 90 minutes).

This issue occurs when passive copper cables are used to connect to Cisco UCS 6536 FI on ports 1 to 8.

Connect the UCS-IOM-2304 to ports 9 to 36 on the Cisco UCS 6536 FI.

Or, use AOC cables or fiber cables.

CSCwd90187

In a setup equipped with Cisco UCS 6536 FI, port goes to Link not connected status when QSFP-100G-DR/FR-S is replaced with QSFP-100G-CUxM under the following conditions:

  • 100G interface

  • interface is configured with FEC Auto

  • interface was using QSFP-100G-FR, QSFP-100G-DR transceivers

  • interface now uses QSFP-100G-CUxM, where CUxM refers to CU1M, CU2M, and so on.

There are two workarounds for this issue:

  • Perform the following steps:

    1. Insert an optic or AOC transceiver that do not have FEC capability. For example, QSFP-100G-SR or QSFP-100G-AOC3M on the interface.

    2. Remove the transceiver in step 1.

    3. Re-insert passive copper cable.

    OR

  • Reboot the FI.

  • CSCwd32544—Cisco Nexus 2348UPQ connected to Cisco UCS 6500 FI series with 40G CU cable does not get discovered in Cisco UCS Manager after configuring the FI ports as server port.

    Workaround—Disable Auto Negotiation for the FI ports.

  • CSCwd48246—Cisco UCS-IOM-2304 or UCS-IOM-2304V2 IOMs may get stuck at identity state when connected to Cisco UCS-FI-6332.

    Workaround—Perform one of the following:

    • Shut and no-shut fabric port

    • Reconfigure fabric port

    • Reset IOM

Release 4.2(2e)

There are no known limitations in release 4.2(2e).

Release 4.2(2d)

  • CSCwb01457—Cisco UCS B200 M5 servers running releases 4.1 or 4.2 and booting from iPXE display Parity Error.

    Workaround—

    • Roll back to release 4.0(4g).

      OR

    • Disable PCIe RAS from BIOS policy.

Release 4.2(2c)

  • CSCwa97427—Cisco UCS Manager release 4.0(4) and earlier have a limit on the size of an image that can be installed in BMC flash. This limit may cause a Cisco UCS B-Series M5 blade server to lose all management capabilities after upgrading from a Cisco UCS release 4.0(4m) or earlier to release 4.2(2c). To stop this issue from occurring, Cisco UCS Manager checks this condition and blocks the upgrade.

    Workaround—While upgrading any Cisco UCS M5 B-Series server from 4.0(4m) or an earlier release, perform a two-step upgrade.

    1. First upgrade the server to any 4.1 release. Cisco recommends latest 4.1(3) patch.

    2. Once the server is running the 4.1 release, upgrade to 4.2(2) release.

  • CSCwc99180—Cisco UCS Manager may block an upgrade process when you try to upgrade B-bundle to release 4.2(2c) without first upgrading the infrastructure A-bundle to 4.2(2c).

    Workaround—Upgrade infrastructure A-bundle to 4.2(2c) first and then upgrade B-bundle.

Release 4.2(2a)

  • CSCwa36214—If you downgrade an Intel® X710 card running version 1.826.0 using Cisco UCS Manager running version 4.2(2a), the adapter downgrades without any error, but the adapter does not get listed in the inventory in the next host reset operation and goes into the recovery mode. In another host reset, the adapter goes into unusable state.

    Workaround—If you wish to downgrade Intel® X710 card from version 1.826.0 to any lower version, it is recommended to perform outside from the Cisco UCS Manager scope to avoid damaging the card. For example, you can downgrade through HSU tool.

  • CSCvz71583 —Support of Precision Time Protocol (PTP) can be enabled only with one vNIC per Cisco UCS VIC 15428 adapter.

  • CSCwb64913—In a setup equipped with Cisco UCS 6400 series FI, when a board controller or BIOS is in the process of activating for any Cisco UCS server, and if at the same time a vLAN configuration or any other non-distruptive change is taking place through a service profile association, then that server reboots even if user-ack for the maintenance policy is set.

    Workaround—Clear pending FlexFlash and board controller activation by resetting the FlexFlash controller:

    • Equipment > Chassis Number > Servers > Server Number > Inventory > Storage > Reset FlexFlash Controller

      OR

    • Clear the pending faults and activating state for the board controller and then apply the service profile association based non-distruptive change.

  • CSCvy34349—In a setup equipped with Cisco B200 M6 servers and Cisco Boot Optimized M.2 RAID Controller, if VMD/Intel VROC is enabled, then BIOS may not display the RAID controller during POST.

    Workaround—Disable VMD/Intel VROC.

Release 4.2(1)

  • Serial over LAN (SoL) configuration does not work on Cisco UCS M6 servers when serial port A is selected as console redirection in BIOS policy

    CSCvy05529—The Serial over LAN (SoL) policy set for Cisco UCS M6 platforms, does not work when serial port A is set as console redirection in the BIOS policy.

    Cisco UCS M6 platforms support only COM 0 for serial redirection. The serial redirection token has to be configured with COM 0 in the BIOS policy for the SoL configuration to work on M6 platforms.

  • OCP Support for DWM on UCS Manager—Dual Wire Management (DWM) is not supported on Cisco UCS C225 M6 Server and Cisco UCS C245 M6 Server. Only Direct Attach and Single Wire Management are supported.

  • CSCwe64267—Cisco UCS Manager does not support firmware upgrade for Intel® X710 card series if the infrastructure A bundle is in any 4.2(1) release and the server C bundle is in any 4.2(2) or later release.

    Workaround—Upgrade Cisco UCS Manager to 4.2(2) or higher release.
