Do not upgrade individual components (only BIOS or only Cisco IMC), since this could lead to unexpected behavior. If you choose to upgrade BIOS, and the Cisco IMC individually and not from the HUU ISO, make sure to upgrade both Cisco IMC, and BIOS to the same container release. If the BIOS and the Cisco IMC versions are from different container releases, it could result in unexpected behavior. Cisco recommends that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS, and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together. 6 Notes for Cisco UCS C-Series Software, 3.1(3)

17 Open Caveats in 3.1(3) CSCvi53766 On the S3260 M5 and S3260 M4 servers, Time Zone configuration page on the Cisco IMC web UI displays a blank screen. Hence you cannot configure time zone using the Cisco IMC web UI. Use CLI to set the time zone. Table 13: BIOS CSCvg61868 CSCvg97305 "DMAR: VT-d detected invalid descriptor: low=<nnn>, high=<nnn>" message appers during the Linux kernel loading and initialization phase. This happens with a single CPU sample, with IO cards like NVMe or PCIe cards on PCIe port 1A or 1B. Uncorrectable memory error injection using Intel ITP probe & CScript always reports error on CPU1 A1 DIMM with Silver CPU Note This issue occurs only with the Silver CPU 4114 CPUs, the other CPUs work as expected. Temporary workaround is to disable VT-d direct IO token from BIOS setup, or Cisco IMC Web UI or CLI. If your setup is running operating system with virtualization support, we recommend you to replace the CPU pair. Ignore the SEL reported during runtime. Cold reboot the host and wait for the POST to complete, check the failed DIMM SEL message or identify the failed DIMM in memory inventory in the setup or Cisco IMC web UI or CLI. CSCvg65199 Option ROM for the NVMe SSDs populated in the front slots: 7,8 and 23 will not be loaded. Hence cannot be seen listed in the Advance page of the setup. None.

Disable the UEFI secure boot using the Cisco IMC web UI and reboot the HUU. 3.1(1d) Known Behaviors The following section lists known behaviors. Known Behaviors in 3.1(3) 3.1(3c) The following is the known behavior in 3.1(3c): Table 21: BMC CSCvj64919 Upgrading Cisco IMC to version 3.1(3c) sets the default fan policy to low power profile. If you want to change the fan policy to a different power policy, you must manually change it. 3.1(3b) You can set the fan policy using one of the following methods: Using the Cisco IMC web UI - Compute -> Power Policies -> Configure Fan Policy. Using the CLI - Scope chassis -> Scope fan-policy- set Fan policy The following are the known behaviors in : 20 Notes for Cisco UCS C-Series Software, 3.1(3)

21 Known Behaviors in Table 22: BIOS CSCve90425 The Cisco IMC Processor Inventory screen of the Cisco UCS C-series M5 servers displays user configured number of cores instead of total available cores. None. CSCvd79734 The values of effective memory and redundant memory (in the mirroring mode) are incorrect on the Cisco IMC Web UI. None. 3.1(1d) Table 23: External Controllers CSCve75610 On LSA (LSI Storage Authority) installed on RHEL 7.3, SBMezz controller IDs are mapped incorrectly as: Controller ID0 - SBMezz2, Controller ID1 - SBMezz1. However, Cisco IMC web UI and CLI display the IDs correctly. None. Table 24: Utilities CSCvc25435 HDD firmware activation fails after an HDD firmware update is done and the firmware displays the older HDD firmware version. This happens when you choose south bridge as RSTE (which is the AHCI mode) in the BIOS Advance settings. Use LSISWRAID mode while performing the HDD firmware update. Known Behaviors in The following are the known behaviors in : Notes for Cisco UCS C-Series Software, 3.1(3) 21

22 Known Behaviors in Table 25: BMC CSCvf93319 After upgrading to version 3.1(2) from 3.1(1), Flexutil controller status displays the following message: "Invalid partition, reset required" Reset the card configuration. Table 26: BIOS CSCvf64564 On the C220 M5 or C240 M5 servers, BIOS password authentication fails after upgrading the server firmware from version 3.1(1) to 3.1(2), and you cannot enter the BIOS Setup screen. Boot the system BIOS to Setup while system is at version 3.1(1), go to the Security page and clear the system password. Now upgrade the server to version 3.1(2) and enter the BIOS setup to set the password of your choice. Table 27: External Controllers CSCva82566 When you place a vnic on the Intel X520 network adapter with user defined MAC, association succeeds but the Web UI and CLI does not display the vnic path. None. 22 Notes for Cisco UCS C-Series Software, 3.1(3)

23 Known Behaviors in 3.1(1d) CSCvf47015 NVMe U.2 and HHHL drives are supported only on the following specific slots in the single CMOD configuration: None. For SFF (U.2) NVMe supported only in slot 1 and slot 17 For HHHL NVMe supported only in slots 1,2,5,8,9 and 10. For the use of NVMe devices, the above slots are supported in a single CMOD configuration. However, if you plug the NVMe devices in the other supported slots that work on the dual CMOD configuration, the NVMe devices are displayed under the Storage Management tab and can be managed. But these devices are not accessible in the BIOS as well as Inventory and cannot be used at the OS level. CSCvf29989 The performance of sn200 is low on the HDDEXT1_SLOT2 and HDDEXT3_slot2 slots, the performance is as expected on the others slots. There is a 17-19% performance drop on the above two slots on random or sequential read. However, on the others slots there only a 2-3% drop which meets standards. None. Known Behaviors in 3.1(1d) The following are the known behaviors in 3.1(1d): Table 28: BMC CSCve82042 Flexflash Virtual Drives disconnects from the host when you perform multiple flexflash resets. This happens due to the controller not being able to detect the installed SD cards. Reset the controller again and reconnect the VD to the host. 3.1(1d) Notes for Cisco UCS C-Series Software, 3.1(3) 23

24 Recommended Best Practices CSCvd00773 When the platform or CPU domain power limit is set to an absolute minimum power value (characterized minimum value) and the correction time to 1 second, sometimes it may take more than 1 second (correction time) to limit power to the set value. No workaround. 3.1(1d) CSCvf48086 When power cap limit for a platform domain is set close to a minimum power limit value, following critical SEL messages may appear during system boot: Node Manager: Thermal Status Sensor for CPU 1, PROCHOT asserted Node Manager: Thermal Status Sensor for CPU 2, PROCHOT asserted These messages get de-asserted during the boot process. These messages are seen as the system tries to retain the power consumption during system boot within the configured power cap value. Configure a higher power cap value. 3.1(1d) Table 29: BIOS CSCvd52950 The SEL "System Software event: Post sensor, Unrecoverable Video Controller Failure [0xFF09] was asserted." is logged and there is no display on the Offboard VGA console. This happens when you have an offboard VGA card that does not have UEFI oprom support and the server is in the UEFI boot mode (default mode). Clear the CMOS to reset the VGA priority to use onboard VGA as the primary video console. 3.1(1d) Recommended Best Practices Upgrading BIOS and Cisco IMC Firmware Cisco provides the Cisco Host Upgrade Utility to assist you in upgrading the BIOS, Cisco IMC, CMC LOM, LSI storage controller, and Cisco UCS Virtual Interface Cards firmware to compatible levels.
