to two CPUs and with the I/O bus reconfigured
- State where the I/O bus reconfiguration function is disabled on a system with a
CPU configuration of two CPUs at initial installation
To use all the PCI slots, enable the I/O bus reconfiguration function and change
the I/O device path. However, you may need to reconfigure the logical domains
because the I/O device path changes.
Precautions for memory reduction
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.
In memory reduction, observe the memory installation rules. For details, see
■
Memory Installation
When reducing memory, you may need to reconfigure the logical domains.
■
For details, see "3.2.14 Configuring Virtual Memory" in the Fujitsu SPARC M12
and Fujitsu M10/SPARC M10 Domain Configuration Guide.
Precautions for HDD/SSD removal
When removing the HDD/SSD, mount the filler unit in the empty slot.
■
Precautions for PCIe card removal
When using the PCI Hot Plug function for active removal of a PCIe card having a
■
multipath setting, you may need to release the target PCIe card from the
multipath configuration. See the manual for the multipath software being used.
When performing active removal 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.
To perform active removal in combination with the dynamic SR-IOV function or
■
the dynamic reconfiguration function for a PCIE endpoint, confirm that the card
supports the respective function. 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 M12 PCI Card
Installation Guide.
After removing the PCIe card, install a PCIe card filler in the PCICS and then
■
mount the PCICS in the SPARC M12-2/M12-2S.
Precautions for SPARC M12-2S removal
To remove a SPARC M12-2S from a building block configuration, use a method
■
other than system-stopped/cold removal. Performing system-stopped/cold
Rules."
