7.2 Precautions for FRU Expansion


7.2 Precautions for FRU Expansion
This section describes the precautions for FRU expansion.
Before performing expansion work, see "(3) Checking the FRU status" in "8.2.2 Identifying a Fault" to confirm that there is no problem with the chassis requiring expansion.
Precautions for CMUU expansion
Caution - The CMUU weighs 10 kg (22 lb). Work must be done by two people if the chassis is mounted at the 24U or higher position of the rack. If the work is done by one person, it may result in an injury or damage to the chassis.
  1. When adding the CMUU, remove the CMU filler unit. Store the removed CMU filler unit in a safe place.
  1. Adding the CMUU also adds a root complex. Enabling the I/O bus reconfiguration function increases the I/O bandwidth. Since doing so changes the PCIe card installation rules and the device path of the I/O device, you may need to reconfigure the logical domains.
    For details, see "A.2 SPARC M12-2 Device Paths" or "A.3 SPARC M12-2S Device Paths" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
  1. To use the added CPU resources after CMUU addition, you need to assign CPU Activations. Check the number of CPU Activation keys registered with the device and the number of CPU Activations assigned to the physical partition, before using them.
  1. To add a CMUU with 64 GB DIMMs mounted, see "Notes on Memory" in the latest version of the Fujitsu SPARC M12 Product Notes.
Precautions for memory expansion
Caution - The CMUU weighs 10 kg (22 lb), and the CMUL weighs 13 kg (29 lb). Work must be done by two people if the chassis is mounted at the 24U or higher position of the rack. If the work is done by one person, it may result in an injury or damage to the chassis.
  1. In memory expansion, observe the memory installation rules.
    For details, see "2.2.1 Memory Installation Rules."
  2. To mount a 64 GB DIMM, see "Notes on Memory" in the latest version of the Fujitsu SPARC M12 Product Notes.
Precautions for HDD/SSD addition
  1. When adding the HDD/SSD, remove the filler unit from the slot in which the HDD or SSD will be mounted. Store the removed filler unit in a safe place.
Precautions for PCIe card addition
  1. When performing active addition using PCI Hot Plug, confirm that the PCIe card supports PCI Hot Plug.
    For details, see "Appendix B Cards That Support PCI Hot Plug and Dynamic Reconfiguration" in the Fujitsu SPARC M12 PCI Card Installation Guide.
  2. To perform active addition in combination with the dynamic SR-IOV function or the dynamic reconfiguration function for a PCIe endpoint, the PCIe card to be added must support the respective function.
    For details, see "Appendix C Cards/On-Board Devices That Support SR-IOV" and "Appendix D Cards/On-Board Devices That Support Assignment of PCIe End Point Devices (PCIe Cards)" in the Fujitsu SPARC M12 PCI Card Installation Guide.
  3. To add a PCIe card, remove the PCIe card filler from the PCICS. Store the removed filler in a safe place.
Precautions for SPARC M12-2S addition
  1. The SPARC M12-2S to be added to a building block configuration must have the XSCF settings information initialized. To add a SPARC M12-2S that has been used in another system, initialize the setting information before adding it.
  2. If you power on the initialized SPARC M12-2S before adding it to a building block configuration, the BB-ID of the OPNL is set in the XSCF, possibly making it unusable for expansion in the building block configuration.
  3. When adding the SPARC M12-2S to a building block configuration, assign BB-IDs in ascending order without duplication.
  4. To use the added CPU resources after SPARC M12-2S addition, you need to assign CPU Activations. Check the number of CPU Activation keys registered with the device and the number of CPU Activations assigned to the physical partition, before using them.
    For details, see "Chapter 5 CPU Activation" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
  5. To add a SPARC M12-2S with 64 GB DIMMs mounted to a building block configuration, see "Notes on Memory" in the latest version of the Fujitsu SPARC M12 Product Notes.
