*1: Physical replacement of CPU and DIMM as hardware is not possible. When replacing the CPU and the
DIMM, the SB is removed by the hot remove of SB. Or the partition is stopped.
*2: All PCI Express cards mounted in the partition must support PCI hot plug.
*3: DR function of PCI_Box is operated with DR function of IOU.
*4: DR feature is supported by only SuSE Linux Enterprise Server 12 x86_64 SP 1.
How to check the dr command package
Execute the following command, and check whether the dr command package has been installed.
# rpm –qa | grep FJSVdr-util
Example:
# rpm -qa | grep FJSVdr-util
FJSVdr-util-RHEL6-1.0.0-1.noarch
In case it has not been installed, see
Type of memory in DR
There are three types of memory related to DR operations as shown below below, depending on the
conditions of use.
- Kernel memory
It is the memory internally used by the operating system. The kernel memory cannot be disconnected
from the system by SB hot-plug operation. It is secured from the memory of the Home SB at startup
- User memory
If is a memory in which the kernel memory is not loaded, the user memory can be hot-removed from the
system by the SB hot plug operation.
- Special memory
It is a hugetlbfs special memory. hugetlbfs cannot be disconnected from the system by SB hot plug
operation. Therefore, this memory is present only on the Home SB.
Notes/Limitations of Dynamic Reconfiguration
