Symptom The LED sensor color is red or amber or blue (or any supported color) even though the LED state is set to OFF.
Workaround Ignore the LED color when the LED state is set to OFF.(CSCth84883)
Symptom SNMPv1 traps are sent when SNMPv2 and SNMPv3 traps are enabled.
Symptom.The Boot Loader version displays extra characters after the CIMC version.
Workaround This is a new feature and displays the U-Boot version.(CSCti49855)
Symptom The AES encryption field does not show the encryption level (128, 256, and so on) on the Web GUI and CLI.
Workaround The SNMP V3 encryption key length must be clearly indicated. The SNMP agent supports AES - 128 bit encryption by default. (CSCtr31577)
Symptom The SNMPv3 traps are not received in the Net-SNMP receiver.
Workaround None. (CSCtr83298)
Symptom The power supply serial number is unavailable in the SNMP inventory because the Power Management Bus (PMBus) has not provided the power information.
Symptom The SNMPv3 walk, with AES encryption enabled, produces a “Decryption Error” when an SNMPv3 trap is triggered by an event. An “authentication failure” error is also encountered on triggering an event with the secure hash algorithm (SHA) authentication. The SHA trap error is encountered with both “authpriv” and “authnopriv” settings. The issue is observed till the master agent is restarted by clicking Save All in the CIMC Web UI SNMP configuration page.
Workaround Use the Message-Digest algorithm 5 (MD5) authentication and DES encryption for v3 user configuration. (CSCtx11173)
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.(CSCtd05874)
Symptom The KVM screen displays a blank screen.
Workaround Use the physical monitor to change the screen resolution. The following resolutions are supported:
- 640x480 (8bpp)
- 800x600 (8bpp)
- 1024x768 (8bpp)
- 1280x1024 (8bpp)
- 640x480 (16bpp)
- 800x600 (16bpp)
- 1024x768 (16bpp)
- 640x480 (24bpp)
- 800x600 (24bpp)
- 1024x768 (24bpp)
- 640x480 (32bpp)
- 1280x1024(32bpp) (CSCtx00839)
Symptom Printing from Web GUI does work from Internet Exploder, but not Firefox.
Symptom When the LSI MegaRAID controller is used with the Cisco Flex Flash, SNMP_Inv_HDD:Disk_IDD N and RN shows 0,0,0 instead of 0,1,2 sequence.
Workaround Use the CIMC Web GUI to query the hard drive inventory.(CSCty26155)
Symptom When the LSI MegaRAID controller is used in conjunction with Cisco Flex Flash card, the SNMP_Inv_HDD:DiskPresence displays missing(11) instead of equipped(10).
Workaround Use the CIMC Web GUI to query the hard drive inventory.(CSCty26198)
Symptom Cisco UCS C220 and UCS C240 servers displays errors when the Power Restore Policy is set to restore-state and an AC power cycle is performed with the host power is ON.
Workaround Set the Power Restore Policy to On with fixed or random delay.(CSCty42040)
Symptom When mapping a removal media using Mac Client, the USB device only supports Read-Only mode.
Workaround Use Windows client or Linux 32 bit client.(CSCty32452)
Symptom After upgrading MegaRAID firmware, sometimes the storage information in the CIMC Web GUI and CLI will be empty.
Workaround Restart the CIMC to get the storage information to be populated in CIMC Web GUI and CLI.(CSCtx08443)
Symptom Occasionally, when BIOS starts, the following message is displayed:
Error on Getting CIMC IP/MAC Address.
Workaround This message can be ignored.(CSCtx27907)
Symptom Occasionally when CIMC boots, the HTTP Web UI will not start.
Workaround Restart the CIMC.(CSCtx19968)
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.
Symptom Product ID information is not displayed in Web GUI for PSUs.
Workaround None.This issue will be addressed in next software release for this platform.(CSCtu09488)
Symptom When running the KVM Viewer client on a 64 bit Linux OS, block devices such as a USB stick or floppy drive will have the read only box checked when you open the vMedia tab. Trying to uncheck the read only box will fail, and devices can only be mapped as read only.
Workaround Use a 32 bit Linux OS or Windows OS for the client system running the KVM Viewer application.(CSCty37812)
Symptom When using the KVM Viewer client application with a 64 bit Linux OS, mapping both floppy disk and removable disk at the same time will cause improper functioning of the application that is, the drive data is invalid and/or cannot be read. Even mapping only a single drive (floppy or removable disk) at a time can yield unexpected failures. For example, after mapping and unmapping a USB stick, click on the exit button of the vMedia tab and reopen the vMedia tab. Now, if you try map the device again the vMedia tab will crash and all themapped devices will be unmapped.
Note Mapping of CD-ROM drives and image files works properly, this problem is observed only when mapping physical Linux block devices such as /dev/sdX.
Workaround Perform the following steps to map physical block devices:
Step 1 Map only a single physical block device at a time (not both floppy and removable device at a time). This will usually work, but may have occasional unexpected failures. Restart the client if the vMedia tab stops functioning.
Step 2 Generate an img file of the block device contents and map this instead, this has no known issues.
Step 3 Use a 32 bit Linux OS / Windows OS / Mac OS client system to run the KVM Viewer/vMedia application.(CSCty42187)
Symptom The KVM viewer version does not display the FCS version, that is, 188.8.131.52. This means the client machine has not downloaded the new.jar file for the KVM/vMedia client and the old client is getting executed. This issue is seen when you use KVM with the old CIMC firmware and then upgraded the CIMC. To check the KVM viewer version, invoke KVM and go to Help >About KVM Viewer. The KVM Viewer version should be 184.108.40.206 for Release 1.4(4a).
Workaround To resolve this issue delete the Java temporary cached files and invoke KVM from CIMC GUI. The Java Control Panel app (javacpl.exe) is in the bin directory of the Java JRE installation.
For Windows, go to in c:\Program Files\Java\<JRE VERSION>\bin and delete the cached Cisco Virtual KVM Console application and re-launch remote presence.
For Linux, go to the Java directory, for example./usr/java/jre1.6.0_26/bin/ControlPanel.
Symptom OS installation hangs when installing from Unified Extensible Firmware Interface (UEFI) environment.
Workaround EFI OS is currently not supported.(CSCtw78721)
Symptom Patrol scrub is disabled when a channel is disabled due to a bad DIMM.
Workaround Replace the bad DIMM. (CSCtx58908)
Symptom When Option ROM run out of space, the POST error 0xA6A0 displays as a critical event.
Workaround In the BIOS setup, disable the Option ROM for adapters for which the Preboot eXecution Environment support is not required.(CSCtx68045)
Symptom The system hangs when you press Control + H. This issue is observed with both the mezzanine card and the 9266 adapter and occurs intermittently but some systems display a high fail rate.
Workaround Perform the following steps:
Step 1 Restart the host.
Step 2 Load the EFI shell and run the drvcfg -s command.
The Web BIOS gets invoked.(CSCty15505)
Symptom The Web BIOS does not respond to mouse clicks.
Workaround Press any key on the keyboard.(CSCtw53469)
Symptom When a bad DIMM (which fails memory initialization) is present in one of the DIMM slots, BIOS may map out the other DIMMs in the same channel as the bad DIMM.
Workaround Remove or replace the bad DIMM.(CSCtx85587)
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)
