5 Working with TAC
6 A problem clearly stated is a problem half solved. Charles F. Kettering Head of research GM
7 Information Gathering What to collect for the Service Request Detailed Problem description When did it start happening Is it reproducible? Logs: tech-support, OS logs, sosreports, mcelogs, LSI MegaCLI logs System Info: Software Version (CICM,BIOS,OS) Hardware (Server model, adapter types & version [enic/fnic]) Additional Info: Screenshots, topology etc
8 Analysis / Corrective Actions What corrective actions have been taken and what was the outcome? Has the system been rebooted? Has the system been upgraded? Check system supportability using the UCS HW and SW Interoperability Tool Check the UCS C - Series Field Notices for possible matches Check the Release Notes for known open caveats

18 Cisco IMC 2.0 Introduction Cisco IMC Firmware Release Naming: CIMC Cisco IMC (In adherence with Cisco branding rules) 1.X 2.X (This will be the 2.0 Release) Release will be branded Cisco IMC 2.0 Supported Platforms: C-Series 22 M3 & C-Series 24 M3 C-Series 220 M3 & C-Series 240 M3 C-Series M4 Platforms (Future) C-Series 3160
19 Cisco IMC 2.0 New Themes & Features Storage Configuration: Local storage management using XML API Advanced RAID Configuration Options via WebUI, CLI and XML API Networking: Cisco IMC IPv6 Support Dynamic DNS Issue ping from WebUI Monitoring: SNMP Phase4 (+ storage changes) Syslog Enhancements (Port) DIMM Blacklisting: Phase2 Fault Engine History Platform Event Traps (PET) removed, PEF Updated
20 Cisco IMC 2.0 New Themes & Features Security BIOS Signing (Signed Update Checking) Secure CIMC Support (Signed Update Checking) UEFI Secure Boot (Windows 2012) PSIRT fixes password hashing using standard algorithms (SHA512) General Precision Boot order control - CLI, Web UI, XML API support Import/Export Enhancements Display FW version of PCIe adapters Standardize BIOS tokens Local User Enhancements KVM Enhancements (Power Controls, Last Boot Capture, Digital Video Recorder Capability, Chat Capability) SCU - ESXi OS install and SAN based ESXi install
21
22 Raid Controller CSCuh86924 ESXi PSOD PF exception 14, LSI Raid Controller i Problem is due to marginal voltage level on an internal voltage rail. Primarily impacts ESXi 4, ESXi 5 and Red Hat 6.4. MegaCLI lsi-fwterm.log will contain one or more of the following messages: "Pmu Msg Fault!!! faultcode "Pmu Msg Fault!!! faultcode " "Pmu Msg Fault!!! faultcode B" "Controller encountered a fatal error and was reset" (multiple instances) Manufacturing New RMA
23 HDD CSCul25263 Seagate 146/300/500GB/1TB/2TB HDDs may stop responding Look for messages in the SEL logs and/or the OBFL logs. You may see a combination of the following messages: RAID / Controller Physical / Virtual Drive Shows as degraded or failed If you see any of the these messages listed in the example below then you may be hitting this issue. BMC:storage:-: SLOT-5: VD 01/1 is now DEGRADED "HDD_07_STATUS: Drive Slot sensor, Drive Fault was asserted". To verify this issue you will have to power cycle the HDD / Server If the issue clears then you have hit this issue and the workaround is temporary. Next, in the collected tech support find the following file /mnt/jffs2/storage-data
24 HDD - Continued CSCul25263 Seagate 146/300/500GB/1TB/2TB HDDs may stop responding The following is an excerpt from the storage-data file. The drive firmware needs to be upgraded. The key information is highlighted. %controller "SLOT-4" %type "RAID" %physical-drive "4" %group inquiry-data The following Seagate hard drives are affected: Seagate 146GB SAS 15K Hard Drive - ST SS - Firmware version 0002 Seagate 300GB SAS 15K Hard Drive - ST SS - Firmware version 0002 Seagate 500GB SATA 7.2K Hard Drive - ST500NM Firmware version 0001 Seagate 1TB SAS 7.2K Hard Drive - ST1000NM Firmware version 0001 Seagate 2TB SAS 7.2K Hard Drive - ST2000NM Firmware version has-error: No +vendor: SEAGATE +product-id:st ss +product-revision-level: 0002 <<======= Need Version 4 or >
25 Troubleshooting What if you still have HDD or Raid Controller Issues? For HDD issues Try reversing the LSI cable ends and check connectivity (Polarity Sensitive) Check \mnt\jffs2\fw_update and if one or more components are not up to date then use update_all Check \mnt\jffs2\storage-data for media errors and failures For Raid Controller issue Check Controller firmware and BIOS If they are not updated then check if HUU detects it and try and upgrade. Collect MegaCLi logs. In the latest code you can download the ttylogs in the same place as a show tech. In 2.0 some of the logs are included in the show tech itself.

30 Cisco IMC 2.0 Features DIMM Blacklisting Gets ECC counts from IPMI ECC sensor Makes blacklisting decisions based on IPMI sensor reading Blacklists DIMM when Uncorrectable ECC error is encountered Maps-out blacklisted DIMM in the subsequent reboot of Host by communicating the decision to BIOS Map-out means, DIMM is excluded from Host memory configuration Maintains ECC counts across reboots in the Blacklisting database Stores the Blacklisting database on DIMM SPD.
31 Cisco IMC 2.0 Features Continued HUU Low Level Firmware Update Till not low level components like FPGA, CPLD, etc. could only be updated via CIMC Cli and had to be done manually. With Eagle Peak release the Low Level Firmware will be updated along with HUU Update. Update All In this case no questions will be asked and Low Level Firmware, if require an update will be updated automatically when CIMC is activated after HUU update. Update CIMC If CIMC is selected with any other component in HUU for update the user will be prompted for Low Level Firmware update. If user selects yes then the on CIMC activation the components will be updated
32 Cisco IMC 2.0 Features Continued vkvm/vmedia Enhancements KVM and vmedia Reconnect Status Bar Host Power Control DVR and Video Player Exporting Recorded Video Server Side (BMC) Video Capture Video Scaling Mini-mode Chat
33 Troubleshooting Backup
34 Replacing a Failed Disk Do NOT replace a disk while the server is shut down! May result in an inactive or offline disk. Replace the disk while after the OS, or at very least RAID Controller option ROM has loaded. An inactive disk is when conflicting COD (configuration on disk) partitions are detected on multiple disks. As the controller does not know which is correct, it disables (makes inactive) one of the configurations. This should only happen during boot time (If the new disk was added when the Server is switched off). If the new disk is added when the Option ROM is already loaded (or the O/S is booted) then the Controller will know which of the disks is foreign (new) and will automatically start a rebuild (if required) onto it.
