4.3.2 Precautions for installation


4.3.2 Precautions for installation
Before performing installation work, see "Checking the FRU status" in "4.2.2  Identifying a failure" to confirm that there is no problem with the chassis requiring installation.
Precautions for expansion of the CPU memory unit upper
  1. When installing a CPU memory unit upper, remove the filler unit. Store the removed filler unit in a safe place because it will be needed if you subsequently remove the CPU memory unit upper. 
  2. If PCI Express cables are not connected to the CPU memory unit lower, you need to add PCI Express cables.
  3. If PCI Express cables are connected to the CPU memory unit lower, you need to add only one PCI Express cable.
  4. If the CPU memory unit upper for the 2CPU configuration of the SPARC M10-4/M10-4S is installed, the root complex is also installed. Then, by enabling the I/O bus reconfiguration function(*1), the I/O bandwidth increases, and the PCIe card installation rules(*2) change. In addition, the I/O bus reconfiguration also changes the device path of the I/O device(*3), so you may have to reconfigure the logical domains.
  5. The type of CPU memory unit varies depending on the number of CPU clocks. They cannot be mixed in the same device, but they can be mixed in a system with a building block configuration.
*1 For details, see the section describing the setpparmode command in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
*2 For details, see the Fujitsu M10/SPARC M10 Systems PCI Card Installation Guide.
*3 For details, see "A.5  SPARC M10-4 Device Paths" or "A.6  SPARC M10-4S Device Paths" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
Precautions for memory expansion
  1. Observe the memory installation rules when you expand memory. For details, see "2.2.1  Memory installation rules."
  2. When you expand memory by 64 GB, apply XCP 2090 or later.
  3. Unless memory modules of 512 GB (64 GB DIMM x 8) are mounted in the 16 DIMM slots under a CPU, memory modules of up to two different capacities can be mounted together. In this case, use the same type within each memory group.
Note - When you expand memory with a different capacity, apply XCP 2052 or later.
Precautions for internal disk expansion
  1. To expand an internal disk, remove the hard disk drive filler unit from the slot in which you will install the internal disk. Store the removed filler unit in a safe place because it will be needed if you subsequently remove the internal disk.
Precautions for PCIe card expansion
  1. Set a multipath depending on the use of the PCIe card when performing active/hot maintenance or active/cold maintenance with PHP.
  2. For active addition using PHP, confirm that the card supports PHP as described in "Appendix A  Cards That Support PCI Hot Plug and Dynamic Reconfiguration" in the Fujitsu M10/SPARC M10 Systems PCI Card Installation Guide. For active addition combined with dynamic SR-IOV and the dynamic reconfiguration function for the PCIe end point, confirm the supported card as described in "Appendix B  Cards That Support SR-IOV" and "Appendix D  Cards That Support the Dynamic Reassignment Function for the PCIe End Point Device (PCIe Card)" in the same manual.
  3. When performing PCIe card expansion, remove the PCIe card filler from the PCIe card cassette. Store the removed filler in a safe place because it will be needed if you subsequently remove the PCIe card.
