Overview of the Server Models

The Cisco UCS C22 M3 Rack Server is a low cost UCS server designed for both performance and density over a wide range of business workloads, including enterprise web/file/print server and HPC. The enterprise-class Cisco UCS C22 M3 server extends the capabilities of the Cisco UCS portfolio in a 1RU form factor with the addition of the Intel Xeon E5-2400 product family. In addition, the Cisco UCS C22 M3 server offers up to two Intel® Xeon® processor E5-2400 processors, 12 DIMM slots, 8 disk drives, and two 1 Gigabit Ethernet LAN-on-motherboard (LOM) ports.

The Cisco UCS C24 M3 Rack Server is designed for both performance and expandability over a wide range of storage-intensive infrastructure workloads, from big data to collaboration. The enterprise-class Cisco UCS C24 M3 server further extends the capabilities of the Cisco UCS portfolio in a 2RU form factor with the addition of the Intel® Xeon® processor Intel Xeon E5-2400 product family. The Cisco UCS C24 M3 offers up to two Intel® Xeon® E5-2400 processors, 12 DIMM slots, 24 disk drives, and two 1 Gigabit Ethernet LAN-on-motherboard (LOM) ports.

The Cisco UCS C22 M3 and the Cisco UCS C24 M3 interfaces with Cisco UCS using the Cisco UCS P81E Virtual Interface Card (VIC). The Cisco UCS P81E VIC is a virtualization-optimized Fibre Channel over Ethernet (FCoE) PCI Express (PCIe) 2.0 x8 10-Gbps adapter designed for use with Cisco UCS C-Series servers. The VIC is a dual-port 10 Gigabit Ethernet PCIe adapter that can support up to 18 PCIe standards-compliant virtual interfaces, which can be dynamically configured so that both their interface types-network interface card (NIC) or host bus adapter (HBA) and identity (MAC address and worldwide name (WWN))-are established using just-in-time provisioning. In addition, the Cisco UCS P81E can support network interface virtualization and Cisco® Data Center Virtual Machine Fabric Extender (VM-FEX) technology.

Known Behaviors

This section lists the known behaviors in Release 1.4(5e):

CIMC

Symptom    During high or medium Serial Over LAN (SOL) traffic, the Intelligent Platform Management Interface (IPMI) LAN interfaces becomes unresponsive.

Workaround   Do not use IPMI queries during high SOL traffic.

Symptom    The Boot Loader version displays extra characters after the CIMC version.

Workaround   This is a new feature and displays the U-Boot version.

Symptom    The system hangs at preboot disk detection screen if only SAS drives are present and the system has no SKUROM.

Workaround   Remove SAS drives and replace with SATA drives and reboot system.

Symptom    When KVM is launched, a "Login Failed" error displays and KVM closes.

Workaround   Wait for 2-3 minutes and relaunch KVM.

Symptom    The Network mode cannot be set to cisco_card mode even though the option is available.

Workaround   Install the Cisco UCS P81E card to move into the cisco_card network mode.

Symptom    In Power Restore Policy, a delay value displays when the delay type is set to random.

Workaround   Ignore the displayed value.

Symptom    When you create a image of file or folder size bigger than 4 GB using vMedia Create image feature, the following message displays:

Create Image Failed.  An error occurred in the Image library.

Workaround   Use files or folders with smaller sizes.

Symptom    If you try to use vMedia to map both an .img file and a physical USB stick (pen/thumb drive) simultaneously, the following message (or a similar one) displays:

Either Virtual media is detached or virtual media redirection for the selected virtual 
disk drive is already is in use by another user

Workaround   Map one drive at a time.

Symptom    KVM and vMedia do not work with mismatched IE and JRE executables.

Workaround   Ensure JRE matches the IE version.

Symptom    The mouse does not work or track in the LSI Web BIOS tool.

Workaround   Use one of the following workarounds:

Set the mouse to relative motion, no acceleration. When running the WebBIOS as a legacy OptionROM, absolute mouse positioning is not supported, and no acceleration gives the best behavior of the two relative positioning modes.

Move the cursor to single cursor mode by using KVM windows > Tools > single cursor. The single cursor mode eliminates the discrepancy between the local cursor movement and the remote cursor movement.

Symptom    BIOS update fails if KVM is launched while BIOS is uploading.

Workaround   Use one of the following workarounds:

Launch the KVM in another browser or session.

Do not launch the KVM if the BIOS upload is in the Uploading stage.

Symptom    When you launch KVM in IE, the following message displays:

Internet Explorer was not able to open this Internet site. The requested site is either 
unavailable or cannot be found.

Workaround   Perform the following steps:


Step 1 In the IE, select Tools > Internet Options.

The Internet Options dialog will pop up.

Step 2 Click the Advanced tab.

Step 3 Uncheck the Do not save encrypted pages to disk option.

Step 4 Click OK.


Symptom    If you disable both SSH and HTTP, connectivity to CIMC is lost.

Workaround   If disabled, reset CIMC to factory default using the F8 utility during POST.

Symptom    CIMC Web GUI does not display after the certificate import process and the browser displays the following message:

Error :
Invalid Server Certificate
A request failed because the server's certificate was invalid.

Workaround   During the certificate import process, provide different values for the Subject Information and Issuer Information fields.

Symptom    In IE, when network mode is changed to cisco_card mode, a "Unable to parse xml" message displays.

Workaround   Use one of the following workarounds:

Update IE browser version to version 8.0.6001.18702 and above.

Use other browser clients like Firefox, Chrome etc.

LSI

Symptom    The server hangs during BIOS POST in the LSI SWRAID drive scan due to mismatch in configuration and you need to hard reset the server and follow the workaround to recover.

Workaround   The system should be switched off and all the drives should be removed except one. Switch on the systems and enter Cntrl+M during LSI SWRAID OPROM during BIOS POST and hot-plug each drive to resolve this issue.

Symptom    The 9220-8i card in LSI Web BIOS shows the Drive enclosure information incorrectly as UCS-C200 instead of C22 for 1U systems and C24 for 2U systems.

Workaround   None.

Open Caveats

This section lists the open caveats for Release 1.4(5e):

CIMC

Symptom    piddump shows generic PID for LSI 9265 card without Battery Backup Unit (BBU) and Broadcom 5709 Dual Port Ethernet Adapter card. The following details are observed:

UCS-RAID-9265 instead of UCS-RAID-9265-NB

N2XX-ABPCI01 instead of N2XX-ABPCI01-M3

Workaround   None. CIMC cannot detect the absence of BBU in LSI and Broadcom firmware revision details.(CSCua38415)

Symptom    The PXUx_VOUT reading displays 1V with a 450W power supply but the actual reading is about 11V.

Workaround   None. (CSCua06141)

Symptom    CIMC recognizes only the SuperCap and all other information like the charge and charging state is not available.

Workaround   None. (CSCtz92792)

Symptom    The CIMC Web GUI displays the battery status as "unknown" when LSI 9265CV-8i with supercap battery is used.

Workaround   Use MegaCLI or LSI Web BIOS to read the battery status. (CSCty64241)

Symptom    The HDD presence cannot be viewed through SNMP.

Workaround   Use either alternate interfaces or do SNMP query again for the HDD inventory after the action. (CSCty60975)

Symptom    The Web GUI and CLI are not consistent in displaying the PSU redundancy status in Cisco C22.

Workaround   None. (CSCty57554)

Symptom    CIMC Web GUI does not reflect the "Reconstruction" virtual disk state after expanding the virtual disk.

Workaround   Use the same interface that you used for configuring the virtual disk to view the "Reconstruction" state. The interface can either be Web GUI or MegaCLI.(CSCtx96912)

Symptom    When using two PSUs, the host does not reboot or shut down but PSU redundancy events would be seen. But, if both PSUs are faulty, the host will reboot continuously or shutdown.

Workaround   None.(CSCtx88937)

Symptom    SEL displays SPD Unknown error.

Workaround   These errors are OEM events and can be decoded through web GUI and CLI. (CSCtx82569)

Symptom    The system hangs when you type Exit in the EFI shell.

Workaround   Hard reset the server to recover from the system hang. (CSCtx64756)

Symptom    The SNMP Hard Disk Inventory starts numbering with 0 while the CIMC HDD sensor starts with 1.

Workaround   None. This symptom occurs because the SNMP Hard disk inventory matches with the storage inventory and both starts with index 0. The hard disk sensor numbering starts with 1 because it matches with the label in the SKU. You need to be aware of the difference and map it accordingly while browsing for a specific HDD detail across sensors and storage inventory. (CSCty58229)

Symptom    The connection to the Virtual Media tab gets disconnected and OS iso that was mapped over the Virtual Media tab disappears as a result of the disconnection.

Workaround   Reboot the server and restart the operating system installation. (CSCtz07699)

Symptom    Duplicate SNMP traps are obtained when you insert Fan 2,4 and 5 in Cisco C22.

Workaround   None. This issue will be fixed in the future release. (CSCua11831)

Symptom    Broadcom adaptors with PID N2XX-ABPCI03-M3 displays the PID as N2XX-ABPCI01.

Workaround   None. (CSCua14401)

Symptom    RAID 10 support on LSI Embedded MegaRAID controller having more than 2 HDD per span fails.

Workaround   None. Currently, RAID 10 only supports up to 4 disks for LSI Embedded MegaRAID, that is, 2 disks per Data Group and only 2 Data Groups per RAID 10. (CSCua06467)

Symptom    The drive Slot ID in LSI Web BIOS and LSI OPROM does not match.

Workaround   Use the slot ID in the LSI Web BIOS as this information is correct. (CSCtz83223)

Symptom    An HDD fault deassert event is logged in SEL when the Locate LED is ON

Workaround   None. This behavior is expected since the same hardware circuit is used to identify HDD fault and to turn on the HDD Locate LED. It is recommended that you turn off the Locate LED and ignore the deassert and assert event caused by the Locate LED. (CSCtz53001)

Symptom    A P1_LVC3_PWRGD event is logged in SEL.

Workaround   None. This is not a critical issue and can be ignored. (CSCua52257)

Symptom    SSH session remains active even after termination using the terminate command.

Workaround   Avoid the terminate session command and always close the SSH connection when you exit. (CSCua67529)

LSI

Symptom    When the I/O is running on two or more hard disks part of a RAID array, the Activity LED is seen blinking GREEN on the hard disks on which the I/O is running and part of the RAID array and also on the adjacent hard disk which is not part of the RAID group.

Workaround   None. You can ignore the Activity LED running on the adjacent hard disk of the RAID array as there is no actual I/O running on this hard disk. (CSCtz10983)

Symptom    The rebuild of drives fail if the RAID group contains both SAS and SATA hard disks.

Workaround   Using both SAS and SATA drives together in the RAID group is not recommended. (CSCtz63094)

Symptom    The system hangs when you type Exit in the EFI shell.

Workaround   Hard reset the server to recover from system hang. (CSCtx64756)

Symptom    The 9220-8i card in LSI Web BIOS shows the Drive Enclosure information incorrectly as UCS-C200 instead be C22 for 1U systems and C24 for 2U systems.

Workaround   None. (CSCtz83273)

BIOS

Symptom    When Broadcom 5709 Gigabit Ethernet adapter is plugged into one of the PCIE slots, the server gets stuck at the BIOS post screen during the booting process.

Workaround   Upgrade the firmware on the Broadcom 5709 Gigabit Ethernet adapter to version 5.2.7 or later.(CSCtx92042)

Symptom    Continuous beep sound is heard when the system is switched on.

Workaround   Do not switch on the CIMC and the host simultaneously. Switch on the host 3 minutes after switching on the power supply.(CSCtz11862)

Symptom    Sometimes "Unable to communicate with CIMC" or "Error in getting the CIMC IP" messages are displayed while booting the server. This results in the CIMC IP and MAC address from getting displayed.

Workaround   Restart the server. (CSCtx96999)

Symptom    When the rack server is managed by UCS Manager and it has a physical CD/DVD drive connected to it with a bootable media, Discovery and Association fails.

Workaround   Use one of the following workarounds:

Disconnect the physical CD/DVD drive

Go to BIOS setup->USB Configuration->USB ports. Disable the USB which has a physical CD/DVD drive connected to it during the discovery and association phases of the UCSM managed rack servers. (CSCty17725)

Symptom    The USB thumb drive mapped through vMedia does not get enumerated as FSx on EFI Shell on Mac vKVM client.

Workaround   Use one of the following workarounds:

Open the KVM client application from a Windows based system.

Connect the USB thumb drive to one of the physical USB ports. (CSCua73451)

Symptom    When an external graphics adapter is present on the system and VGA priority is set to Offboard VGA Primary, the KVM Video screen gets stuck with the following message:

Configuring Platform Hardware.

Workaround   None. This is an expected behavior. (CSCua93109)
