Document Version Release Date Details 2 05/02/2017 Updated resolution with permanent fix, firmware version 8.7.84 (bundle 2017.03) 1 02/24/2017 Original document release The HPE Superdome X BL920s Gen9 server blades support both the 32GB PC-2133 and PC-2400 DDR4 LR DIMMS. It is currently supported to install the 32GB PC-2133 and 32GB PC-2400 LRDIMMS on the same server blade; however, they can NEVER be mixed on the same DRAM bus or in lockstep pairs on a server blade. The blade(s) with this invalid configuration will fail Power-On Self-Test (POST) and the partition(s) will not power on. This is an architectural issue that cannot be addressed in a firmware update. If 32GB PC-2133 and 32GB PC-2400 LRDIMMS are installed on the same server blade and installed in a supported configuration AND the current firmware revision is 8.5.3 or lower, DIMM speed mismatch errors will be logged and the blade(s) that have this mix, will be indicted and marked as degraded. All of the memory, if properly installed, will be available and the partition(s) will power on. Always replace the 32GB DDR4 DIMMs with a like for like DIMM. Some events that are typically seen in the Onboard Administrator (OA) Forward Progress Log (FPL) when DIMMS are mixed and in the same lockstep pair or DRAM bus are as follows: Examples of supported and unsupported 32GB PC2133 and PC2400 mixed DIMM configurations: Supported Partition powers on but blade is indicted Unsupported partition will fail to power on OA-CLI> show blade info 1 cpusocket-1/1/0: Intel Xeon E7-8800 v3 2800 MHz dimm-1/1/0/1 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/2 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/3 : empty dimm-1/1/0/4 : empty dimm-1/1/0/5 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/6 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/7 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/8 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/9 : empty dimm-1/1/0/10: empty dimm-1/1/0/11: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/12: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/13: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/14: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/15: empty dimm-1/1/0/16: empty dimm-1/1/0/17: 32GB 4Rx4 PC4-2133P-LD0 <dimm-1/1/0/18: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/13: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/14: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/15: empty dimm-1/1/1/16: empty dimm-1/1/1/17: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/18: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/19: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/20: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/21: empty dimm-1/1/1/22: empty dimm-1/1/1/23: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/24: 32GB 4Rx4 PC4-2133P-LD0 Socket 1 Memory: 512 GB OA-CLI> show blade info 1 cpusocket-1/1/0: Intel Xeon E7-8800 v3 2800 MHz dimm-1/1/0/1 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/2 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/3 : empty dimm-1/1/0/4 : empty dimm-1/1/0/5 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/6 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/7 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/8 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/9 : empty dimm-1/1/0/10: empty dimm-1/1/0/11: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/12: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/13: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/14: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/15: empty dimm-1/1/0/16: empty dimm-1/1/0/17: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/18: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/19: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/20: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/21: empty dimm-1/1/0/22: empty dimm-1/1/0/23: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/0/24: 32GB 4Rx4 PC4-2133P-LD0 Socket 0 Memory: 512 GB cpusocket-1/1/1: Intel Xeon E7-8800 v3 2800 MHz dimm-1/1/1/1 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/2 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/3 : empty dimm-1/1/1/4 : empty dimm-1/1/1/5 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/6 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/7 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/8 : 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/9 : empty dimm-1/1/1/10: empty dimm-1/1/1/11: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/12: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/13: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/14: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/15: empty dimm-1/1/1/16: empty dimm-1/1/1/17: 32GB 2Rx4 PC4-2401ZZ-LA0 dimm-1/1/1/18: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/19: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/20: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/21: empty dimm-1/1/1/22: empty dimm-1/1/1/23: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/1/1/24: 32GB 4Rx4 PC4-2133P-LD0 Socket 1 Memory: 512 GB DIMM loading rules:
Any HPE Integrity Superdome X BL920s Gen9 server blade installed in an Integrity Superdome X chassis or HPE ConvergedSystem S00 servers configured with 32GB PC4-2133 or PC4-2400 LR-DIMMS.
With firmware version 8.7.84 (bundle 2017.03), server blades with a mix of 32GB and 64GB DDR4 PC-2133 and PC-2400 DIMMs will no longer be indicted or marked as degraded. The firmware is available here: http://h20566.www2.hpe.com/hpsc/swd/public/detail?sp4ts.oid=7595549&swItemId=MTX_9b0f27233db84735b0e772f254 Note: It is still not supported to have 32GB PC-2133 and 32GB PC-2400 LRDIMMS mixed on the same DRAM bus or in lockstep pairs on a Blade . Before replacing the DIMM, installing any memory upgrades or making memory configuration changes, confirm what type of memory is installed and order compatible memory DIMMs. If a replacement DIMM is being ordered and the required DIMM speed is not available but the other speed is, order at least 6 DIMMS of the same speed and type in order to stay within the configuration rules of not mixing speeds within a lockstep pair and DRAM bus. To determine what type of DIMMS are installed in a specific slot on a server blade, use the "show blade info" command or the "df dimm Blade#" and locate the DIMM slot and type. Note: Most of the output from these two commands has been removed in the example below for 2133 DIMMS: Hawk-OA> show blade info 4 Server Blade #4 Information: Type: Server Blade Manufacturer: HP Product Name: BL920s Gen9 Part Number: A0S01A System Board Spare Part Number: A0R69-69001 Serial Number: SGxxxxxWYVY UUID: 7XXXXX-0A92-5E06-9EB6-XXXXXXXXCBCD Server Name: [Unknown] Asset Tag: [Unknown] Firmware Bundle Revision: 8.5.3 nPartition Revision: 8.5.3 Cpusocket-1/4/0: Intel Xeon E7-8800 v3 2800 MHz dimm-1/4/0/1 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/2 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/3 : empty dimm-1/4/0/4 : empty dimm-1/4/0/5 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/6 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/7 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/8 : 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/9 : empty dimm-1/4/0/10: empty dimm-1/4/0/11: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/12: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/13: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/14: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/15: empty dimm-1/4/0/16: empty dimm-1/4/0/17: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/18: 32GB 4Rx4 PC4-2133P-LD0 dimm-1/4/0/19: 32GB 4Rx4 PC4-2133P-LD0 Hawk-OA> df dimm 4 <== Blade 4 Server blade #4 DIMM SPD FRU Info: Location 1: FRU NAME: Socket 0 DIMM 1A DIMM Label: 32GB 4Rx4 PC4-2133P-LD0 JEDEC SPD Rev: 0x10 DIMM Max Speed: 1066 MHz Module Type: 0x04 (LRDIMM) SDRAM Capacity: 4096 MB SDRAM Banks: 4 SDRAM Groups: 4 SDRAM Organization: 0x18 Device Width: 4 bits Number of Ranks: 4 SDRAM Bus Width: 0x0B Primary Bus Width: 64 bits Extension Bus Width: 8 bits Module Capacity: 32768 MB Module Mfg ID: 0x80AD (Hynix Semiconductor) Mfg Part #: HMA84GL7MMR4N-TF Mfg Revision Code: 0x00 Mfg Location: 0x01 Mfg Year: 2015 Mfg Week: 43 Mfg Serial #: 0x315AF2AE Mfg Unique Serial #: 0x80AD011543315AF2AE DRAM Mfg ID: 0x80AD (Hynix Semiconductor) HPE SmartMemory: Valid Or, use the OA GUI: Enclosure information -> Device Bays -> "Select Blade" -> Information Tab: The DIMM replacement part numbers are as follows: DIMM PN DIMM Description Platform Spare PN 752372-081 32GB PC4-2133-LR BL920S Gen9 774174-001 809084-391 32GB PC4-2400-LR BL920S Gen9 867285-001 The DIMM upgrade kits for these systems are as follows: H7B38A: HP Superdome X DDR4 128GB (4x32GB) PC4-2133 Load Reduced CAS-15 Memory Kit P9H75A: HP Superdome X DDR4 128GB (4x32GB) PC4-2400 Load Reduced CAS-17 Memory Kit In order to avoid DIMM mismatch events and blade indictments, it is recommended that the different DIMM speeds, 2133 and 2400, not be mixed on a HPE Superdome X BL920s Gen9 blade until an updated version of the firmware becomes available. Ensure that like DIMMs are ordered for replacement DIMMS or when installing memory upgrades.
